Method Detail

getAddress

public long getAddress()

Description copied from interface: Closure.Handle

Gets the native code address of the closure. This can be passed into a native function that takes a function pointer.

Specified by:

getAddress in interface Closure.Handle

Returns:

The native address of the closure code.

setAutoRelease

public void setAutoRelease(boolean autorelease)

Description copied from interface: Closure.Handle

Sets whether the closure memory should be released when the Handle is garbage collected or not.

Specified by:

setAutoRelease in interface Closure.Handle

Parameters:

autorelease - If true, the closure memory is automatically managed, else the closure memory must be explicitly freed.

dispose

public void dispose()

Description copied from interface: Closure.Handle

Releases the closure memory back to the operating system. Although the closure trampoline memory will normally be released when the Handle is garbage collected, this may not happen for some time, and is non-deterministic. This allows explicit control over memory reclamation.

Specified by:

dispose in interface Closure.Handle

free

public void free()

Specified by:

free in interface Closure.Handle
