Member Function Documentation

virtual const OFConditionBase* OFConditionBase::clone (   )  const [pure virtual]
 

this method returns a pointer to a OFConditionBase object containing a clone of this object.

If deletable() is true, the clone must be a deep copy allocated on the heap. If deletable() is false, the clone should be a pointer to this.

Returns:
clone of this object, either deep copy or alias.

Implemented in OFConditionConst, and OFConditionString.

Referenced by OFCondition::operator=().

virtual unsigned long OFConditionBase::codeAndModule (   )  const [pure virtual]
 

returns a combined code and module for this object.

code is lower 16 bits, module is upper 16 bits

Implemented in OFConditionConst, and OFConditionString.

Referenced by code(), module(), and operator==().

virtual OFBool OFConditionBase::deletable (   )  const [pure virtual]
 

checks if this object is deletable, e.g.

all instances of this class are allocated on the heap.

Returns:
true if deletable, false otherwise

Implemented in OFConditionConst, and OFConditionString.

Referenced by OFCondition::~OFCondition().

OFBool OFConditionBase::operator!= (  const OFConditionBase &  arg  )  const [inline]
 

comparison operator, not equal.

Compares status, code and module but not error text.

Parameters:
arg argument to compare to
Returns:
false if equal, true otherwise

Definition at line 132 of file ofcond.h.

References code(), module(), and status().

OFBool OFConditionBase::operator== (  const OFConditionBase &  arg  )  const [inline]
 

comparison operator.

Compares status, code and module but not error text.

Parameters:
arg argument to compare to
Returns:
true if equal, false otherwise

Definition at line 122 of file ofcond.h.
