Interface CypherExpressionVisitor

All Known Implementing Classes:

VariableReplacementVisitor

public interface CypherExpressionVisitor

This class is made to provide generic visitor functionalities to traverse expression trees. The visit call is made recursive through the accept method in CypherExpression
