Node * Pin::copy (   )  const [virtual]

Copies the node. Implements Node. Definition at line 27 of file streepin.cpp. References Pin().

string Pin::evaluate (  const NameSpace &  nameSpace  )  const [virtual]

Computes the value of the expression (only basic atihmetic and string operations). Implements Node. Definition at line 34 of file streepin.cpp.

virtual string Pin::getName (   )  const [inline, virtual]

Returs string representing node type or name for List. Implements Node. Definition at line 18 of file streepin.h. References CPin.

virtual SType Pin::getType (   )  const [inline, virtual]

Returns type of the node. Implements Node. Definition at line 16 of file streepin.h. References SPin, and SType.

void Pin::getVariables (  VariableList &  vlist  )  const [virtual]

Returns list of variables used in the node. Implements Node. Definition at line 31 of file streepin.cpp.

bool Pin::match (  const Node *  p, Assignment &  assign, const NameSpace &  nameSpace )  const [virtual]

Matches node p to the node. If node matches sets the assignment. Implements Node. Definition at line 11 of file streepin.cpp. References SPin.

bool Pin::matchToBegining (  const List *  p, Assignment &  assign, const NameSpace &  nameSpace )  const [virtual]

Matches the list to the begining of p. Implements Node. Definition at line 15 of file streepin.cpp.

ostream & Pin::php (  ostream &  os  )  const [virtual]

Writes node to the stream as php. Implements Node. Definition at line 7 of file streepin.cpp.

ostream & Pin::print (  ostream &  os  )  const [virtual]

Writes node to the stream. Implements Node. Definition at line 3 of file streepin.cpp.

Node * Pin::substitute (  const Assignment &  assign  )  [virtual]

Substitutes variables in the node accordingly to the given assignment. Implements Node. Definition at line 23 of file streepin.cpp.
