Constructor Detail

ConstraintStatement

public ConstraintStatement(org.antlr.runtime.Token t,
                           Script scr,
                           ConstraintsCatalog cat,
                           ErrorReporter errs)

Make a new Tree parser.

Parameters:

t - the root symbol

cat - the catalog of available constraints

errs - the errors to report

Method Detail

go

public BtrpOperand go(BtrPlaceTree parent)

Build the constraint. The constraint is built if it exists in the catalog and if the parameters are compatible with the constraint signature.

Overrides:

go in class BtrPlaceTree

Parameters:

parent - the parent of the root

Returns:

Content.empty if the constraint is successfully built. Content.ignore if an error occurred (the error is already reported)
