Syntaxes

This class defines these predicates that act on the objects of this class. In addition, objects of this class can access the predicates defined by the base class AstNodeProperties. An object of this class is an object of AstNodeProperties class.

Predicates	Description
is(required CommaExpression &commaExpression)	Finds syntax nodes of the type CommaExpression in your C/C++ code and returns them as commaExpression. For example, in (foo(), bar()), this predicate matches the comma expression node for foo(), bar().
isa(Cpp.Node.Node node)	Checks if node is a CommaExpression. Use this relation if you want to negate the condition (for example: not Cpp.CommaExpression.isa(n)).
cast(Cpp.Node.Node node, required CommaExpression &cast)	Finds syntax nodes of the type CommaExpression from the nodes in node. Retrieval occurs if node is compatible with the CommaExpression type. Use this relation if you need further CommaExpression properties.
left(CommaExpression self, Cpp.Node.Node &child)	Matches the left side of the comma expression. For example, in foo(), bar(), this predicate matches foo().
right(CommaExpression self, Cpp.Node.Node &child)	Matches the right side of the comma expression. For example, in foo(), bar(), this predicate matches bar().
isEnclosedInCommaExpression(Cpp.Node.Node child)	Checks if child appears inside a CommaExpression.
getEnclosingCommaExpression(Cpp.Node.Node child, required CommaExpression &parent)	Finds the nearest enclosing CommaExpression ancestor of child and returns it as parent.
