Method Detail

reset

public abstract void reset()

clearDFA

public void clearDFA()

Clear the DFA cache used by the current instance. Since the DFA cache may be shared by multiple ATN simulators, this method may affect the performance (but not accuracy) of other parsers which are being used concurrently.

Throws:

UnsupportedOperationException - if the current instance does not support clearing the DFA.

Since:

4.3
