Constructor Detail

PartialLexTreeConstraintSet

public PartialLexTreeConstraintSet()

Constructs an empty constraint set.

PartialLexTreeConstraintSet

public PartialLexTreeConstraintSet(Sexp tree)

Constructs a set of PartialLexTreeConstraint objects forming a tree structure from the specified syntactic tree. The specified tree is lexicalized using a head finder.

Parameters:

tree - the syntactic tree from which to construct a tree of constraints

Method Detail

buildConstraintSet

protected void buildConstraintSet(Sexp tree)

Builds the constraint tree from the specified unlexicalized parse tree. As a necessary side-effect, the UnlexTreeConstraintSet.root and UnlexTreeConstraintSet.leaves data members will be set/populated by this method.

Overrides:

buildConstraintSet in class UnlexTreeConstraintSet

Parameters:

tree - the tree from which to build this constraint set

main

public static void main(String[] args)

Test driver for this class.

Parameters:

args -
