Constructor Details

DeclrationInConstraintFinder

public DeclrationInConstraintFinder(ConstraintSyntaxTree cst)

Default constructor for this class.

Parameters:

cst - A constraint where all nested AbstractVariable's should be found.

DeclrationInConstraintFinder

public DeclrationInConstraintFinder(ConstraintSyntaxTree cst,
 boolean considerReferences)

Constructor for this class to specify whether (reference) values should also be visited.

Parameters:

cst - A constraint where all nested AbstractVariable's should be found.

considerReferences - true values will also be visited to discover used declarations inside reference values, false these values will be ignored.

Method Details

getDeclarations

public Set<AbstractVariable> getDeclarations()

Returns all AbstractVariable's inside the given ConstraintSyntaxTree.

Returns:

A set of nested AbstractVariable's (This set must not be null).

visitAnnotationVariable

Description copied from interface: IConstraintTreeVisitor

Visits a let expression.

Parameters:

let - the let expression which should be visited

visitContainerOperationCall

public void visitContainerOperationCall(ContainerOperationCall call)

Description copied from interface: IConstraintTreeVisitor
