sexpress.hpp File Reference

Detailed Description

The basic S-expression types and methods.

The most notable things defined in this file are probably the SReference class which is the main interface to the S-expression model provided by InteLib; the SExpression abstract class which is the common ancestor of all the S-expressions; and the classes SExpressionInt, SExpressionFloat, SExpressionString, SExpressionLabel and SExpressionCons, which represent basic atomic S-expression types as well as the Cons (from which all lists are built).

const unsigned int intelib_simple_string_limit = sizeof(char*)

"Simple" string max. length Strings of this many chars are stored inside the SExpressionString object, without creating dynamic strings Definition at line 101 of file sexpress.hpp.

SReference* PTheEmptyList

Empty List. This global pointer points to the SExpression object used as the empty list representation. If only the sexpress/ part of the library is used, the pointer remains 0 (NULL), that is, unbound reference is used to mark the end of a list. The lisp/ part of the library changes this pointer during initialization so that it points to the symbol NIL Definition at line 381 of file sexpress.cpp. Referenced by IntelibX::AddStack(), SExpressionDoubleList::AddToBegin(), SQueue::Append(), Charp2LispNumber(), SExpressionBacklink::DisconnectBack(), LExpressionLambda::DoApply(), SchExpressionLambda::DoApply(), LExpressionContext::GetAllSymbols(), SchExpressionContext::GetAllSymbols(), SDoubleListRange::GetFirst(), SDoubleListRange::GetLast(), SBacklinkRef::InsertAfter(), SDoubleListRange::LeftEndMover::JumpToLast(), SDoubleListRange::RightEndMover::JumpToLast(), LSymbolNIL::LSymbolNIL(), SDoubleListRange::LeftEndMover::operator SBacklinkRef(), SDoubleListRange::RightEndMover::operator SBacklinkRef(), SBacklinkRef::operator,(), SDoubleListRange::LeftEndMover::operator--(), SDoubleListRange::RightEndMover::operator--(), LListConstructor::operator^(), LFunctionConstructor::operator^(), SchListConstructor::operator^(), SListConstructor::operator^(), LListConstructor::operator|(), SchListConstructor::operator|(), SListConstructor::operator|(), LReference::operator~(), LListConstructor::operator~(), SchListConstructor::operator~(), SchReference::operator~(), SExpressionBacklink::Prev(), SBacklinkRef::Remove(), SExpressionBacklink::RemoveNext(), SBacklinkRef::SBacklinkRef(), SchLabelEmptyList::SchLabelEmptyList(), SDoubleListRange::SDoubleListRange(), SQueue::SQueue(), IntelibContinuation::Step(), and SDoubleListRange::WhatsAfter().
