public class DeclaredReferenceExpression
extends Expression
implements HasType.TypeListener
An expression, which refers to something which is declared, e.g. a variable. For example, the expression a = b, which itself is a BinaryOperator, contains two DeclaredReferenceExpressions, one for the variable a and one for variable b , which have been previously been declared.
