Detailed Description

base protocol for ZFTypeId

Member Function Documentation

typeIdClass()

virtual const ZFClass * ZFTypeInfo::typeIdClass ( void ) const

pure virtual

return the proper wrapper type class if available

if available:

• if the type is ZFObject type, the object's class would be returned
• if the type is not ZFObject type, a proper ZFTypeIdWrapper would be returned

genericValueStore()

virtual zfbool ZFTypeInfo::genericValueStore ( zfauto & obj, const void * v ) const

pure virtual

advanced generic value access

note:

• this is raw access without type check, you must ensure the access is valid
• since aliased type (ZFTYPEID_ALIAS_DECLARE) share same base ZFTypeInfo, the type returned from ZFTypeInfoForName won't work and always result to crash for aliased type, it's recommended to access by creating new instance of ZFTypeId, instead of access by ZFTypeInfoForName

when access:

• for ZFObject type
  • obj: should store the ZFObject itself
  • v: must be a pointer to T_Type of ZFTypeId<T_Type>, e.g. zfauto, zfweakT<SomeZFObject>, SomeZFObject *
• for non-ZFObject type
  • obj: should store the proper ZFTypeIdWrapper
  • v: must be a pointer to T_Type of ZFTypeId<T_Type>

genericArrayNew()

virtual ZFCoreArrayBase * ZFTypeInfo::genericArrayNew ( void ) const

pure virtual

create generic array type

impl must create by ZFCoreArrayBase::refNew
