NAME

TPath::TypeCheck - applies type constraint on nodes

VERSION

version 1.007

Role of an object that checks the class of a node against the class it knows it can handle.

Expects a node. Confesses if the node is of the wrong type.

node_type: If set on object construction, all nodes handled by the TPath::TypeCheck will have to be of this class or an error will be thrown. Can be used to enforce type safety. The test is only performed on certain gateway methods -- TPath::Expression::select() and TPath::Index::index() -- so little overhead is incurred.
