Method Detail

charsetTransfer

public CharSet charsetTransfer(CharSet a1,
                               CharSet a2)

Description copied from class: BinaryOperation

Transfer function for character set analysis.

Specified by:

charsetTransfer in class BinaryOperation

getPriority

public int getPriority()

Description copied from class: Operation

Returns priority of this operation. When approximating operation loops in grammars, operations with high priority are considered first.

Specified by:

getPriority in class Operation

isAssertion

public boolean isAssertion()

Description copied from class: BinaryOperation

Returns whether this operation is an assertion. By default, this returns false.

This is used when breaking operation cycles in the grammar.

Overrides:

isAssertion in class BinaryOperation

op

public Automaton op(Automaton a1,
                    Automaton a2)

Description copied from class: BinaryOperation

Binary operation on automata.

Specified by:

op in class BinaryOperation

Parameters:

a1 - first input automaton, should not be modified

a2 - second input automaton, should not be modified

Returns:

output automaton

toString

public String toString()

Description copied from class: Operation

Returns name of this operation.

Specified by:
