Package android.databinding.tool.expr

Class FieldAssignmentExpr

java.lang.Object

android.databinding.tool.expr.Expr

android.databinding.tool.expr.FieldAssignmentExpr

All Implemented Interfaces:

android.databinding.tool.expr.VersionProvider, android.databinding.tool.processing.scopes.LocationScopeProvider, android.databinding.tool.processing.scopes.ScopeProvider

public class FieldAssignmentExpr
extends Expr

This is used by inverse field access expressions to assign back to the field. For example, @={a.b} is inverted to @{code a.b = value;}
