Method Detail

clone

public Object clone()

Need cloning for processing of macro references. See comments on PatternElement.clone()

Overrides:

clone in class PatternElement

addConstraint

public void addConstraint(Constraint newConstraint)

Add a constraint. Ensures that only one constraint of any given annotation type and negation state exists.

isMultiType

public boolean isMultiType()

Indicates whether this constraint deals with only one type of annotation or multiple types.

finish

public void finish()

Finish: replace dynamic data structures with Java arrays; called after parsing.

Specified by:

finish in class PatternElement

toString

public String toString()

Create a string representation of the object.

Overrides:

toString in class Object

toString

public String toString(String pad)

Create a string representation of the object.

Specified by:

toString in class PatternElement

shortDesc

public String shortDesc()

Returns a short description.

getUnfinishedConstraints

public ArrayList<Constraint> getUnfinishedConstraints()

Get the current list of unfinished Constraint objects. This can only be used before the finish() method is used.

Returns:

the array list of constraint objects. Will be null after the finish() method has been used.

getConstraints

public Constraint[] getConstraints()

Get the finished Constraint objects. Can only be used after the finish() method has been used.

Returns:

an array of constraint objects. Will be null before the finish() method has been used.
