public class Boxed
extends Struct

A mechanism to wrap opaque structures registered by the type system.

Method Summary

boolean
equals(Object other)
Check if two objects refer to the same (native) object.
static Boxed
getBoxedFromHandle(Handle hndl)
Gets a Boxed instance for the given Handle.
int
hashCode()
Returns a hash code value for the object.

Method Details

equals

public boolean equals(Object other)
Check if two objects refer to the same (native) object.
Parameters:
other - the reference object with which to compare.
Returns:
true if both objects refer to the same object.

getBoxedFromHandle

public static Boxed getBoxedFromHandle(Handle hndl)
Gets a Boxed instance for the given Handle. If no Java object currently exists for the given Handle, this method will return null. You should then instantiate the required Java class using the class' handle-constructor. For example:
 // Get a Handle from somewhere (typically as a parameter to a method
 // used as a callback and invoked from the C JNI side).
 SomeGtkClass finalobj = null;
 Boxed obj = Boxed.getBoxedFromHandle(handle);
 if (obj == null) {
     finalobj = new SomeGtkClass(handle);
 } else {
     finalobj = (SomeGtkClass) obj;
 }
 
NOTE: This is for internal use only and should never need to be used in application code.

hashCode

public int hashCode()
Returns a hash code value for the object. This allows for using Boxed objects as keys in hashmaps.
Returns:
a hash code value for the object.
