Detailed Description

property for ZFObject type

Typedef Documentation

ZFPropertyCallbackIsValueAccessed

typedef zfbool(* ZFPropertyCallbackIsValueAccessed) (const ZFProperty *property, zfany const &ownerObj)

used to check whether the property has been accessed

usage:

const ZFProperty *propertyInfo = ...;
propertyInfo->callbackIsValueAccessed(propertyInfo, ownerObj);

ZFPropertyCallbackIsInitValue

typedef zfbool(* ZFPropertyCallbackIsInitValue) (const ZFProperty *property, zfany const &ownerObj, zfauto *outInitValue)

used to check whether the property is in init value state

usage:

const ZFProperty *propertyInfo = ...;
propertyInfo->callbackIsInitValue(propertyInfo, ownerObj, zfnull);

Note

the outInitValue can be set to access the init value (only when the checker returned false)

ZFPropertyCallbackDynamicRegisterInitValueGetter

typedef zfauto(* ZFPropertyCallbackDynamicRegisterInitValueGetter) (const ZFProperty *property)

callback to setup init value for ZFPropertyDynamicRegister

returned object must be valid to ZFTypeInfo::typeIdClass
