Interface IMetadataValue

All Known Subinterfaces:

IComplexMetaValue, ISimpleMetaValue

public interface IMetadataValue

Holds the value of a metadata element.

This interface is not intended to be instantiated (only used as a super-interface). When the value is a Literal (isSimple() returns true), an instance of this interface may be cast to ISimpleMetaValue, and the table found at ITypedValue.getData() is used to determine the type returned from ITypedValue.getData(). When the value is a Resource (isSimple() returns false), an instance of this interface may be cast to IComplexMetaValue.

Method Summary

boolean	equals(IMetadataValue value) returns true if this IMetadataValue is equal to the passed IMetadataValue This should test the metadata ID and the value for equality.
IMetadataValueModel	getModel() Returns the model for this type of metadata value as it is defined in the context's schema.
boolean	isSimple()
void	remove() Removes this value from its IMetadata container Note: This operation is only applied to any backing data store after IContext.applyUpdates() is called.
