Method Detail

public String getLeftmostDerivation(int maxSteps)

protected abstract int getLeftmostDerivation(StringBuffer buf, int step)

Get derivation and return how many you did (less than requested for subtree roots.

public String getLeftmostDerivationStep(int step)

Walk parse tree and return requested number of derivation steps. If steps <= 0, return node text. If steps == 1, return derivation string at step.
