Gets or sets the category associated with this type.

The category is used primarily to group similar types (or instances of) in a user interface.

Attempting to set to a non-string value type implicitly converts the value to a string before assignment.

Setting this to undefined causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is null.

Setting this to null or to an empty string clears the attribute and sets it to null, thus ignoring any inherited value.

Gets or sets the isAdvanced attribute of this type.

Types with isAdvanced attributes set to false are typically immediately accessible to the user. An advanced type typically escapes the expected flow of utilization, yet it is sufficiently relevant to be shown in a user interface.

Setting this to a Nully value causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is false.

Inherited From: pentaho.type.Type#isProperty

Gets a value that indicates whether this type, and all of the value types of any property values, cannot be changed, from the outside.

The value of Complex#isReadOnly is false.

A Complex type is necessarily read-only if its base complex type is read-only. Otherwise, a Complex type can be marked read-only, but only upon definition and if the base complex type does not have any properties.

All of the properties of a read-only complex type are implicitly marked read-only. When the valueType of a property is an element type, it must be a read-only type. When the valueType of a property is a list type, then its element type must be read-only.

Gets or sets the label of this type.

When set to a non-Nully and non-String value, the value is first replaced by the result of calling its toString method.

When set to an empty string or a nully value, the attribute value is reset.

When reset, the attribute assumes its default value (except on the top-root type, Instance.type, in which case it has no effect).

The default value is the inherited value.

The initial value of the attribute on the top-root type is "instance".

Gets or sets the mixin types that are locally mixed into this type.

Can be set to either type identifiers, instance classes or type instances and arrays thereof.

When set to a Nully value, nothing is done.

Inherited From: pentaho.type.Type#mixins

Gets or sets the ordinal associated with this type.

The ordinal is used to disambiguate the order with which a type (or an instance of it) is shown in a user interface.

Setting this to a Nully value causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is 0.

Gets the root type of this type hierarchy.

Even though the ultimate type root of types defined in this system is Instance, the system is designed to represent multiple type hierarchies, each representing concrete, more meaningful concepts.

When deriving a type from Instance, it can be marked as the root of a type hierarchy, by specifying the isRoot keyword argument to extend.

Typically, root types are immediate subtypes of Instance. However, this is not enforced and it is up to the developer to decide at what level a practical, meaningful type root arises.

For example, Value is the root of value types. However, Property, also an immediate subtype of Instance, is not considered a root type. It is the immediate subtypes of Property (each root property within a complex type) which are considered roots. This aligns with users expectations of what an attribute named root in a property type should mean.

Gets the source module identifier of this type.

The source identifier is the module identifier of the actual AMD/RequireJS module that provides the type and may be different from the identifier when an AMD package or custom mapping is configured for the module.

Normalizes a given value specification.

Usually, "deserialization" is handled in a type's constructor. However, for proper handling of the configure operation, the Type API needs to normalize new value specifications to decide whether it can configure operations an existing instance instead of constructing a new one. This, obviously, has to be done outside of a constructor.

For example, some complex types can serialize as a single string if only its main property is specified. In such cases, this method would return a normal, object, generic specification containing the given value as the value of the main property.

This method calls the _normalizeInstanceSpec when the specified value specification is not Nully.

Creates a specification that describes this type.

If an ambient specification context, currently exists, it is used to manage the serialization process. Otherwise, one is created and set as current.

This method creates a new pentaho.type.SpecificationScope for describing this type, and any other instances and types it references, and then delegates the actual work to pentaho.type.Type#toSpecInContext.

This method returns a reference to this type that is appropriate to be the value of an inline type property that is included on a specification of an instance of this type.

When a type has an identifier, its id (or its alias) is returned.

For anonymous types, a temporary, serialization-only identifier is generated. In the first occurrence in the given scope, that identifier is returned, within a full specification of the type, obtained by calling toSpecInContext. In following occurrences, only the previously used temporary identifier is returned.
