Method Detail

getName

public java.lang.String getName()

setUserDefinedType

public void setUserDefinedType(java.lang.String userDefinedType)

If this is root, its type should be set while parsing the XML document

Parameters:

userDefinedType - The type of this identifier

computeUniqueKey

protected java.lang.String computeUniqueKey()

Specified by:

computeUniqueKey in class Expr

getUserDefinedType

public java.lang.String getUserDefinedType()

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

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

constructDependencies

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

Specified by:

constructDependencies in class Expr

asPackage

protected java.lang.String asPackage()

Overrides:

asPackage in class Expr

generateCode

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

Specified by:

generateCode in class Expr

setDeclared

public void setDeclared()

isDeclared

public boolean isDeclared()

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.

generateInverse

public Expr generateInverse(ExprModel model,
                            Expr value,
                            java.lang.String bindingClassName)

Overrides:

generateInverse in class Expr

cloneToModel

public Expr cloneToModel(ExprModel model)

Specified by:

cloneToModel in class Expr

toString

public java.lang.String toString()

Overrides:

toString in class Expr
