java.lang.Object oracle.jdeveloper.audit.service.ValueHandle
public class ValueHandle
A handle to a named serializable value (e.g., the value of a JavaBeans
property). A value handle supplies both a value and an serializable
representation of that value, and can be created from either a value or
a representation. The representation does not describe the type of a
value; the type must be explicitly supplied when the value is needed (see
getValue(java.lang.Class>)
).
A representation is one of three things:
Converter
; or
The implementations of the equals(java.lang.Object)
, hashCode()
, and compareTo(oracle.jdeveloper.audit.service.ValueHandle)
methods use only the name
; they ignore both
value and representation.
