Constructor Detail

Method Detail

action

public void action(ActionCode actionCode, Object param)

execute

public int execute()

Invoke a java hook. The xEnv is the representation of the current execution environment ( the jni_env_t * )

Each context contains a number of byte[] buffers used for communication. The C side will contain a char * equivalent - both buffers are long-lived and recycled. This will be called at init time. A long-lived global reference to the byte[] will be stored in the C context.
