Constructor Details

IDecisionVariableInConstraintFinder

public IDecisionVariableInConstraintFinder(Configuration config)

Single constructor for this class.
This will not start the visitation, for this the #accept(net.ssehub.easy.varModel.cst.IConstraintTreeVisitor) must be called.

Parameters:

config - The underlying configuration, from which the IDecisionVariables shall come from.

Method Details

getVariables

public Set<IDecisionVariable> getVariables()

Returns all AbstractVariable's inside the given ConstraintSyntaxTree.

Returns:

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

visitAnnotationVariable

public void visitAnnotationVariable(AttributeVariable variable)

Description copied from interface: IConstraintTreeVisitor

Visits a AttributeVariable.

Parameters:

variable - the attribute variable which should be visited

visitLet

public void visitLet(Let let)

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

Visits a container operation call (e.g. quantors, iterators).

Parameters:

call - the container operation call

visitCompoundAccess

public void visitCompoundAccess(CompoundAccess access)

Description copied from interface: IConstraintTreeVisitor

Visits a compound access node.

Parameters:

access - the compound access node

visitValue

protected void visitValue(Value value)
