Method Detail

visitConstantValue

public void visitConstantValue(ConstantValue value)

Description copied from interface: IConstraintTreeVisitor

Visits a constant value.

Specified by:

visitConstantValue in interface IConstraintTreeVisitor

Parameters:

value - the value which should be visited

visitParenthesis

public void visitParenthesis(Parenthesis parenthesis)

Description copied from interface: IConstraintTreeVisitor

Visits a parenthesis.

Specified by:

visitParenthesis in interface IConstraintTreeVisitor

Parameters:

parenthesis - the parenthesis which should be visited

visitComment

public void visitComment(Comment comment)

Description copied from interface: IConstraintTreeVisitor

Visits a comment.

Specified by:

visitComment in interface IConstraintTreeVisitor

Parameters:

comment - the comment node which should be visited

visitOclFeatureCall

public void visitOclFeatureCall(OCLFeatureCall call)

Description copied from interface: IConstraintTreeVisitor

Visits an OCL feature call.

Specified by:

visitOclFeatureCall in interface IConstraintTreeVisitor

Parameters:

call - the feature call which should be visited

visitMultiAndExpression

public void visitMultiAndExpression(MultiAndExpression expression)

Description copied from interface: IConstraintTreeVisitor
