Method Detail |
---|
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)
PropertyDefinition.getTypeDefinition()
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.
