virtual SString SExpressionString::TextRepresentation  )  const [virtual, inherited]
 

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

Implements SExpression.

Reimplemented in SExpressionClassicAtom.

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.

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.
