Constructor Detail

LambdaExpr

public LambdaExpr(Expr expr,
                  CallbackExprModel callbackExprModel)

Method Detail

getExpr

public Expr getExpr()

getCallbackExprModel

public CallbackExprModel getCallbackExprModel()

resolveType

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

Specified by:

resolveType in class Expr

constructDependencies

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

Specified by:

constructDependencies in class Expr

getCallbackWrapper

public CallbackWrapper getCallbackWrapper()

resolveListeners

public Expr resolveListeners(android.databinding.tool.reflection.ModelClass valueType,
                             Expr parent)

Overrides:

resolveListeners in class Expr

computeUniqueKey

protected java.lang.String computeUniqueKey()

Specified by:

computeUniqueKey in class Expr

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

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

generateCode

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

Specified by:

generateCode in class Expr

cloneToModel

Specified by:

cloneToModel in class Expr

generateConstructor

public java.lang.String generateConstructor()

markAsUsed

public void markAsUsed()

Overrides:

markAsUsed in class Expr

getInvertibleError

protected java.lang.String getInvertibleError()

Specified by:

getInvertibleError in class Expr

Returns:

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

toExecutionPath

public java.util.List<ExecutionPath> toExecutionPath(java.util.List<ExecutionPath> paths)

Overrides:

toExecutionPath in class Expr

getExecutionPath

public final ExecutionPath getExecutionPath()

getCallbackId

public int getCallbackId()

setup

public void setup(android.databinding.tool.reflection.ModelClass klass,
                  ModelMethod method,
                  int callbackId)

toString

public java.lang.String toString()

Overrides:

toString in class Expr
