public interface PropertyValue

Specifies the type and current value of a property. Methods of the subclasses of type definition allow access to the data value held in the property value object.

Method Summary

TypeDefinition	getType() Returns the type definition for this property value.
Object	getValue() Returns the value of the property through a generic Java object interface.

Method Detail

getType

TypeDefinition getType()

Returns the type definition for this property value.

Methods of the returned type definition can be used to manipulate a property value. For example, for a value of AAF UInt32 type, the following methods are available on TypeDefinitionInteger:

• Number getInteger(PropertyValue)
• PropertyValue createValueFromNumber(Number)
• void setInteger(PropertyValue, Number)

Returns:

Type of this property value.

PropertyDefinition.getTypeDefinition()

getValue

Object getValue()

Returns the value of the property through a generic Java object interface. Alternative type-specific access methods are provided in each type definition.

For example, for a property value of a UInt32 type, this method returns an Integer. Values will need to be cast to appropriate types by the application. The value returned may be null, which may indicate that an optional property was not present.

Returns:

Value of this property.
