pentaho.data.filter.Or

The Or filter represents a boolean disjunction (an Or) filter.

This filter selects the elements that are selected by at least one of a series of other filters: operands.

In terms of set operations, the Or filter corresponds to the union of all of its operands' subsets.

_emit(event) : pentaho.lang.Event
 
Protected

Emits an unstructured event and returns it, unless it was canceled.

When this method is called, the listeners of existing registrations are notified synchronously, by priority order and then registration order, until either the event is canceled or all of the listeners have been notified.

It is safe to register or unregister to/from an event type while it is being emitted. However, changes are only taken into account in subsequent emissions.

If a listener function throws an error, the event processing is interrupted. No more registrations are processed and the error is passed to the caller.

Source: javascript/web/pentaho/lang/EventSource.js, line 261

Inherited From: pentaho.lang.EventSource#_emit

Parameters:
Name Default Value Summary
event : pentaho.lang.Event

Optional

A predicate that indicates if a given event object is in a canceled state.
errorHandler : function
 
Optional

When specified with a null value, no error handling is performed and errors thrown by listeners are thrown back to this method's caller. When unspecified or specified as undefined, defaults to a function that simply log the listener errors, and let execution continue to following listeners. The function arguments are: the error, the event, the event type and the event phase.
Returns:
Name Description
object | null

The event payload object or null, when the event is canceled.
_emitSafe(event) : pentaho.lang.Event
 
Protected

Variation of the _emit method in which errors thrown by event listeners are caught and logged.

andNot(exclude) : pentaho.data.filter.Abstract

Creates a filter that is the "difference" between this filter and a variable number of other filters.

var result = this.and(filter.negate());

var willIEverGetAResult = result.toDnf();

This implementation works first by converting both this filter and the exclude argument to DNF, assuming that these can be so converted in a reasonable time. Then, the difference is performed using an efficient algorithm.

getf(name, sloppy) : string

Gets the string representation of the value of a property.

This method reads the value of the property by calling Complex#get.

When the latter returns a Nully value, "" is returned. Otherwise, the result of the value's toString() method is returned.

For a Simple type, this corresponds to returning its formatted attribute, when it is not null. For Complex and List types, varies with the implementation.

Inherited From: pentaho.type.Complex#getf

Parameters:
Name Default Value Summary
name : string | pentaho.type.Property.Type

The property name or type object.
sloppy : boolean
 
Optional
 false

Indicates if an error is thrown if the specified property is not defined.
Returns:
Name Description
string

The string representation of the value, or "".
Throws:
Name Description
pentaho.lang.ArgumentInvalidError

getv(name, sloppy) : any | pentaho.type.Complex | pentaho.type.List | Nully

Gets the primitive value of the value of a property.

This method reads the value of the property by calling Complex#get.

When the latter does not return a Nully value, the result of the value's valueOf() method is returned.

For a Simple type, this corresponds to returning its value attribute. For Complex and List types, this corresponds to the value itself.

Returns:
Name Description
pentaho.data.filter.Abstract

A negated filter.
Implements:
off(typeOrHandle, observer)

Removes one registration given its handle, or all registrations of a given event type (or types) and observer (or listener function).

To remove an event registration, it is sufficient to call the dispose method of the registration handle returned by on, upon registration. Alternatively, as a convenience syntax, the registration handle can be passed as the single argument to this method.

It is safe to unregister from an event type while it is being emitted. However, any registrations removed during the current emission will still execute.

Specifying an event registration handle that has already been disposed of has no effect. Specifying an event type and observer (or listener function) that have no registrations has no effect.

Source: doc-js/pentaho/lang/IEventSource.jsdoc, line 131

Inherited From: pentaho.lang.EventSource#off

Parameters:
Name Default Value Summary
typeOrHandle : nonEmptyString | Array.<nonEmptyString> | pentaho.lang.IEventRegistrationHandle

The type or types of events, or an event registration handle to dispose of. When a string, it can be a comma-separated list of event types.
observer : pentaho.lang.IEventObserver | pentaho.lang.EventListener | pentaho.lang.EventListenerAsync

The event observer (or listener function). Required when typeOrHandle is not an event registration handle; ignored, otherwise.

See also:  pentaho.lang.IEventSource#on

Implements:
on(type, observer, keyArgs) : pentaho.lang.IEventRegistrationHandle

Registers an observer (or listener function) for an event(s) of a given type(s).

Optionally, a listening priority may be specified to adjust the order by which an observer is notified, relative to other listeners.

Note that if an observer is registered more than once to the same event type, a new registration is created each time and its listeners will be called once per registration.

It is safe to register for an event type while it is being emitted. However, new registrations are only taken into account in subsequent emissions.

When type represents multiple event types, the returned event registration handle is a composite registration for all of the event types.

This method is compatible with the dojo/on API.

Source: doc-js/pentaho/lang/IEventSource.jsdoc, line 90

Inherited From: pentaho.lang.EventSource#on

Parameters:
Name Default Value Summary
type : nonEmptyString | Array.<nonEmptyString>

The type or types of events. When a string, it can be a comma-separated list of event types.
observer : pentaho.lang.IEventObserver | pentaho.lang.EventListener | pentaho.lang.EventListenerAsync

The event observer (or listener function).
keyArgs : object
 
Optional

Keyword arguments.

Parameters:
Name Default Value Summary
priority : number
 
Optional
 0

The listening priority. Higher priority observers are notified of an event before any lower priority observers. The priority can be set to -Infinity or Infinity. In case two observers are assigned the same priority, the registration order determines which is notified first.
Returns:
Name Description
pentaho.lang.IEventRegistrationHandle

An event registration handle that can be used for later removal.

toDnf() : pentaho.data.filter.True | pentaho.data.filter.False | pentaho.data.filter.Or

Converts a copy of this filter into Disjunctive Normal Form and returns it.

A filter in DNF is one of:

  1. A True filter - filters everything.
  2. A False filter - filters nothing.
  3. An Or of Ands of, possibly negated, (non-degenerate) terminal filters, such as: IsEqual.

DNF is particularly useful for representing filters because, excluding its degenerate cases, it is the natural form of a filter that selects a set of rows, such as:

(country = "us" and productLine = "cars") or (country = "pt" and productLine = "jets")

Generally, DNF conversion is computationally expensive, and, for some types of filters, can not terminate in a reasonable amount of time. One such type of filter is that which results from a difference operation, such as filterA.and(filterB.negate()). Directly converting such a structured filter to DNF will usually not terminate soon enough. For such a reason, and because it is such a common operation, the Filter API provides an optimized difference operator: andNot which is able to keep computational cost low enough for practical cases, . The resulting filter can safely be converted to DNF.

The result of this operation is cached.

Source: javascript/web/pentaho/data/filter/abstract.js, line 446

Inherited From: pentaho.data.filter.Abstract#toDnf

Returns:
Name Description
pentaho.data.filter.True | pentaho.data.filter.False | pentaho.data.filter.Or

toJSON() : UJsonValue

Creates a top-level JSON specification that describes this instance.

Attributes which do not have a JSON-compatible specification are omitted. Specifically, for inline types, attributes with a function value are not supported.

This method simply calls pentaho.type.Instance#toSpec with argument keyArgs.isJson as true and exists for seamless integration with JavaScript's JSON.stringify method.

Returns:
Name Description
UJsonValue

A JSON-compatible specification.

See also:  pentaho.type.Instance#toSpec

Implements:
toSpec(keyArgs) : pentaho.type.spec.UInstance

Creates a specification that describes this value.

If an ambient specification context, currently exists, it is used to manage the serialization process. Otherwise, one is created and set as current. Then, the actual work is delegated to pentaho.type.Instance#toSpecInContext.

Source: javascript/web/pentaho/type/value.js, line 184

Inherited From: pentaho.type.Value#toSpec

Parameters:
Name Default Value Summary
keyArgs : Object
 
Optional

The keyword arguments object. Passed to every value and type serialized within this scope.

Please see the documentation of value subclasses for information on additional, supported keyword arguments.

Parameters:
Name Default Value Summary
isJson : boolean
 
Optional
 false

Generates a JSON-compatible specification. Attributes which do not have a JSON-compatible specification are omitted.
declaredType : pentaho.type.Type
 
Optional

The base type of this value's storage location. If the value does not have this exact type, its inline type property must be included in the specification. Otherwise, it can be omitted. When unspecified, the inline type property is only included if forceType is true.
forceType : boolean
 
Optional
 false

Forces inclusion of the inline type property, _, in the specification.
omitFormatted : boolean
 
Optional
 false

Omits the formatted value on Simple values' specifications.
preferPropertyArray : boolean
 
Optional
 false

Indicates that, if possible, array form is used for Complex values' specifications.

The array form of a complex value cannot be used when its type must be inlined.
includeDefaults : boolean
 
Optional
 false

When true, all of the properties of Complex values are serialized. When false, the default, only properties whose value is different from their default value are serialized.

Only applies to complex values that are serialized in object form. In array form, all of the properties of complex values are serialized independently of their value.
omitProps : Object
 
Optional

An object whose own property names with a truthy value are the names of the properties of the current complex type to omit from the serialization.

Only applies when a complex is output in object form. In array form, all properties are output whatever their value.

This argument only applies to complex values and is not passed through to the values of their properties.
Returns:
Name Description
pentaho.type.spec.UInstance

A specification of this value.
toSpecInContext(keyArgs) : any

Creates a specification that describes this instance.
