Package android.databinding.tool.expr

Class ListenerExpr

java.lang.Object

android.databinding.tool.expr.Expr

android.databinding.tool.expr.ListenerExpr

All Implemented Interfaces:

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

public class ListenerExpr
extends Expr

This wraps an expression, but makes it unique for a particular event listener type. This is used to differentiate listener methods. For example:

     public void onFoo(String str) {...}
     public void onFoo(int i) {...}

Method Detail

resolveType

protected android.databinding.tool.reflection.ModelClass resolveType(android.databinding.tool.reflection.ModelAnalyzer modelAnalyzer)

Specified by:

resolveType in class Expr

injectSafeUnboxing

public void injectSafeUnboxing(android.databinding.tool.reflection.ModelAnalyzer modelAnalyzer,
                               ExprModel model)

Description copied from class: Expr

Called after experiment model is sealed to avoid NPE problems caused by boxed primitives.

Specified by:

injectSafeUnboxing in class Expr

getMethod

public ModelMethod getMethod()

getTarget

public Expr getTarget()

getName

public java.lang.String getName()

isDynamic

public boolean isDynamic()

Description copied from class: Expr

Whether the result of this expression can change or not. For example, 3 + 5 can not change vs 3 + x may change. Default implementations checks children and returns true if any of them returns true

Overrides:

isDynamic in class Expr

Returns:

True if the result of this expression may change due to variables

constructDependencies

protected java.util.List<Dependency> constructDependencies()

Specified by:

constructDependencies in class Expr

computeUniqueKey

protected java.lang.String computeUniqueKey()

Specified by:

computeUniqueKey in class Expr

generateCode

public android.databinding.tool.writer.KCode generateCode()

Specified by:

generateCode in class Expr

cloneToModel

public Expr cloneToModel(ExprModel model)

Specified by:

cloneToModel in class Expr

getInvertibleError

public java.lang.String getInvertibleError()

Specified by:

getInvertibleError in class Expr

Returns:

The reason the expression wasn't invertible or null if it was invertible.

toString

public java.lang.String toString()

Overrides:

toString in class Expr
