Class WyalFile.Expr.VariableAccess

java.lang.Object

wybs.lang.SyntacticElement.Impl

wybs.util.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.VariableAccess

All Implemented Interfaces:

Cloneable, Comparable<wybs.lang.SyntacticItem>, WyalFile.Expr, WyalFile.Stmt, wybs.lang.SyntacticElement, wybs.lang.SyntacticItem

Enclosing interface:

WyalFile.Expr

public static class WyalFile.Expr.VariableAccess
extends wybs.util.AbstractSyntacticItem
implements WyalFile.Expr

Represents a use of some variable within an expression. For example, in x + 1 the expression x is a variable access expression. Every variable access is associated with a variable declaration that unique identifies which variable is being accessed.
