Detailed Description

UserLispFunction instances are wrapped by this class.

Such a function is a closure, too, but is closed by the empty context

Member Function Documentation

virtual void LExpressionUserCFunction::DoApply (  int  paramsc, const SReference *  paramsv, IntelibContinuation &  lf )  const [virtual]

The method to do the job. Implements SExpressionFunction. Definition at line 169 of file llambda.hpp.

SString LExpressionUserCFunction::TextRepresentation (   )  const [virtual]

Text representation of the S-expression. Returns the text string which represents the given S-expression as for real Lisp (for example, (25 36 49)) Implements SExpression. Definition at line 185 of file llambda.cpp.

void SExpressionFunction::Apply (  int  paramc, const SReference *  paramv, IntelibContinuation &  cont )  const [inherited]

Definition at line 24 of file lispform.cpp. References SExpressionFunction::DoApply(), SExpressionFunction::max_param, and SExpressionFunction::min_param.

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.

virtual bool SExpression::SpecificEql (  const SExpression *   )  const [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 in SExpressionInt, SExpressionFloat, SExpressionChar, and SExpressionString. Definition at line 235 of file sexpress.hpp. Referenced by SchReference::IsEql(), and LReference::IsEql().

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.
