public java.nio.FloatBuffer get()

Description copied from interface: ResourceHandle

Returns the resource from this handle. Note that this resource may only be valid between calls to ResourceHandle.acquire() and ResourceHandle.release(). Clients should preferably not store the returned object, but always access the resource by calling this method. This method may return null if the resource has not properly been acquired.

Specified by:

get in interface ResourceHandle<java.nio.FloatBuffer>

Returns:

The resource

acquire

public void acquire()

Description copied from interface: ResourceHandle

Has to be called before the resource may be obtained

Specified by:

acquire in interface ResourceHandle<java.nio.FloatBuffer>

release
