Detailed Description

Classic atom.

The purpose of this class is just to represent the difference between `CAT' and `"CAT"' being read by the IntelibReader in case no real package is given. You can use it for your own purposes, too.

Note:

This class is declared here because slexer.cpp needs it, but it is no good to declare it in slexer.hpp because lexer.hpp is not intended to be included by user at all.

Definition at line 407 of file sexpress.hpp.

Member Function Documentation

virtual SString SExpressionClassicAtom::TextRepresentation (   )  const [virtual]

The representation includes double quotes. All special characters are converted to standard C string escapes Reimplemented from SExpressionString.

const char* SExpressionString::GetValue (   )  const [inherited]

Definition at line 384 of file sexpress.hpp. Referenced by SExpressionExtvarname::TextRepresentation().

virtual bool SExpressionString::SpecificEql (  const SExpression *  other  )  const [protected, virtual, inherited]

Are the two objects EQL (while not EQ). This function is overriden by those SExpressions able to be EQL while being not EQ. Warning: It is not demanded that this function return true if it's arguments are the same SExpression (that is, they're EQ). It is only called by the EQL predicate implementation when it has been checked that the operands are not the same object. Reimplemented from SExpression.

const IntelibTypeId& SExpression::TermType (   )  const [inherited]

Actual S-expression type. Definition at line 195 of file sexpress.hpp. Referenced by SReference::DynamicCastGetPtr(), SchReference::IsEql(), LReference::IsEql(), SReference::SimpleCastGetPtr(), SchReference::TextRepresentation(), and LReference::TextRepresentation().

bool SExpression::IsChangeable (   )  const [inherited]

Can it be changed during the lifetime of the object? Definition at line 198 of file sexpress.hpp. References IntelibTypeId::IsChangeable().

virtual SExpression* SExpression::Clone (   )  const [virtual, inherited]

Clone a changeable object. The method should return the pointer created with new Note: It can (and should) return null pointer for non-changeables Warning: This method will hang your program being called for a looped data structure, including looped lists, a hash table which references a list in which it is a member, etc. If you create a changeable S-expression, you MUST make sure this method duplicates your object in such a way that nothing is shared between the old and new objects, that is, changing the new object can not in any way change the old object. Reimplemented in SExpressionBacklink, SExpressionCons, SExpressionHashTable, SExpressionRawBuffer, and SExpressionVector. Definition at line 214 of file sexpress.hpp.

bool GarbageSafe::CanDie (   )  [protected, inherited]

Is it OK to delete the object now? Our children have no access to the private attribute RefCount and should never need it except when checking if the destruction is not an error. This solves the problem. Definition at line 53 of file refcount.hpp.

Member Data Documentation

IntelibTypeId SExpressionClassicAtom::TypeId [static]

Identifier for the set of all possible S-expressions. Note: It never can be the value of term_type_id because SExpression is an abstract class. SExpression::TypeId is used for unification, to identify the whole world of S-expressions. IntelibTypeId::IsSubtypeOf(SExpression::TypeId) is true for all objects of IntelibTypeId class. Guess why. Reimplemented from SExpressionString. Referenced by SExpressionClassicAtom().
