Constructor Detail

CallbackArgExpr

public CallbackArgExpr(int argIndex,
                       java.lang.String name)

Method Detail

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 IdentifierExpr

Returns:

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

setClassFromCallback

public void setClassFromCallback(android.databinding.tool.reflection.ModelClass modelClass)

resolveType

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

Overrides:

resolveType in class IdentifierExpr

constructDependencies

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

Overrides:

constructDependencies in class IdentifierExpr

generateCode

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

Overrides:

generateCode in class IdentifierExpr

computeUniqueKey

protected java.lang.String computeUniqueKey()

Overrides:

computeUniqueKey in class IdentifierExpr

getInvertibleError

public java.lang.String getInvertibleError()

Overrides:

getInvertibleError in class IdentifierExpr

Returns:

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

getName

public java.lang.String getName()

Overrides:

getName in class IdentifierExpr

cloneToModel

public Expr cloneToModel(ExprModel model)

Overrides:

cloneToModel in class IdentifierExpr
