Method Details

getID

@ISProperty(name="id",
            description="This UUID is used to identify the instance uniquely.",
            readonly=true,
            mandatory=true)
UUID getID()

Returns the unique identifier (UUID) of the element.

Specified by:

getID in interface IdentifiableElement

Specified by:

getID in interface Type

Returns:

The UUID of the element.

setID

void setID(UUID uuid)

Sets the unique identifier (UUID) for the element.

Specified by:

setID in interface IdentifiableElement

Specified by:

setID in interface Type

Parameters:

uuid - The UUID to set.

getMetadata

@ISProperty(name="metadata",
            mandatory=true,
            description="Metadata associated with the instance that is automatically created/updated by the system.")
Metadata getMetadata()

Returns the metadata associated with the element.

The metadata is included in JSON serialization only if it is not null.

Specified by:

getMetadata in interface IdentifiableElement

Specified by:

getMetadata in interface Type

Returns:

The Metadata of the element, or null if none is set.

setMetadata

void setMetadata(Metadata metadata)

Sets the metadata for the element.

Specified by:

setMetadata in interface IdentifiableElement

Specified by:

setMetadata in interface Type

Parameters:

metadata - The Metadata to associate with the element.

getName

@ISProperty(name="name",
            readonly=true,
            mandatory=true)
String getName()

Returns the name of the type.

Specified by:

getName in interface Type

Returns:

The type name.

getDescription

@ISProperty(name="description",
            readonly=false,
            mandatory=true)
String getDescription()

Returns the description of the type.

Specified by:

getDescription in interface Type

Returns:

The type description.

isAbstract

@ISProperty(name="abstract",
            readonly=true,
            mandatory=true)
boolean isAbstract()

Checks if the type is abstract.

Specified by:

isAbstract in interface Type

Returns:

true if the type is abstract, false otherwise.

getExtendedTypes

@ISProperty(name="extendedTypes",
            readonly=true,
            mandatory=true)
List<String> getExtendedTypes()

Returns the types that this type extends.

A List because the order carries meaning: it is the declaration order of the direct parents -- the local precedence order C3 linearization requires -- and it must survive serialization and persistence unchanged. A Set would map to an unordered store and lose it.

Specified by:

getExtendedTypes in interface Type

Returns:

The parent type names, in declaration order.

getProperties

@ISProperty(name="properties",
            readonly=false,
            mandatory=true)
List<PropertyDefinition> getProperties()

Returns the properties defined by this type.

A List because the order carries meaning: properties are read in the order the Java class declares them, which is the intended reading order for anyone looking at the type definition. A Set would map to an unordered store and lose it.

Specified by:

getProperties in interface Type

Returns:

The PropertyDefinitions, in declaration order.
