Field Detail

DEBUG

private static final boolean DEBUG
Debug flag

patternElementDisjunction1

private ArrayList patternElementDisjunction1
An array of arrays that represent PatternElement conjunctions during parsing of the .jape. Each conjunction is considered as being disjunct with the next. (I.e. they are or'd, in the same way as expressions around "||" in C and Java.) Set during parsing; replaced by finish().

patternElementDisjunction2

private PatternElement[][] patternElementDisjunction2
The pattern element disjunction for transduction - Java arrays.

currentConjunction

private ArrayList currentConjunction
An array of PatternElements making up a conjunction. It is a member of patternElementDisjunction. This is the one we're adding to at present. Used during parsing, not matching.
Constructor Detail

ConstraintGroup

public ConstraintGroup()
Anonymous constructor.
