Package android.databinding.tool.expr

Class ArgListExpr

java.lang.Object

android.databinding.tool.expr.Expr

android.databinding.tool.expr.ArgListExpr

All Implemented Interfaces:

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

public class ArgListExpr
extends Expr

This is a special expression that is created when we have an adapter that has multiple parameters.

When it is detected, we create a new binding with this argument list expression and merge N bindings into a new one so that rest of the code generation logic works as expected.
