Method Detail

getILPConstraints

public abstract List<ILPConstraint> getILPConstraints(edu.illinois.cs.cogcomp.sl.core.IInstance x,
                                                      InferenceVariableLexManager variables)

getViolatedILPConstraints

public abstract List<ILPConstraint> getViolatedILPConstraints(edu.illinois.cs.cogcomp.sl.core.IInstance x,
                                                              edu.illinois.cs.cogcomp.sl.core.IStructure y,
                                                              InferenceVariableLexManager variables)

The subset of constraints that are violated.

Parameters:

x -

y -

Returns:

getConstraintInput

public edu.illinois.cs.cogcomp.sl.core.IInstance getConstraintInput()

The input that this constraint operates upon need not be the full input to the problem. This function returns the part of the input that is relevant to this constraint. By default, it it returns null. The only way in which it will not be null is if setConstraintInput is used to explicitly set the input.

Returns:

setConstraintInput

public void setConstraintInput(edu.illinois.cs.cogcomp.sl.core.IInstance input)

getConstraintOutput

public edu.illinois.cs.cogcomp.sl.core.IStructure getConstraintOutput(edu.illinois.cs.cogcomp.sl.core.IStructure y)

setConstraintOutputGenerator

public void setConstraintOutputGenerator(ITransformer<edu.illinois.cs.cogcomp.sl.core.IStructure,edu.illinois.cs.cogcomp.sl.core.IStructure> transformer)

isDelayedConstraint

public boolean isDelayedConstraint()
