Constructor & Destructor Documentation

acdk::lang::dmi::DmiClient::DmiClient (  const DmiClient &  other  )  [inline, private]

acdk::lang::dmi::DmiClient::DmiClient (  int  formatFlags = TpFtAcdkType|TpFtFqName  )

virtual acdk::lang::dmi::DmiClient::~DmiClient (   )  [inline, virtual]

Member Function Documentation

virtual void acdk::lang::dmi::DmiClient::castTo (  ScriptVar &  value, const::acdk::lang::dmi::ClazzInfo *  toType )  [pure virtual]

After checked with typeDistance() use this method to do the cast. This method may changes the type of value. Parameters: value  the value to cast. On succes the type value may be changed by this method type  information of the target type, implemented by the target member/method argument Implemented in acdk::lang::dmi::AcdkDmiClient, and acdk::lang::dmi::AcdkStdWeakTypeDmiClient.

int acdk::lang::dmi::DmiClient::getCurInvokeFlags (   )  [static]

return a thread local copy of the current invokation flags See also: acdk::lang::dmi::ClazzInvokeInfo

virtual int acdk::lang::dmi::DmiClient::getScriptVarCastFlags (   )  const [pure virtual]

return the standard casting flags as a combination of ScriptVarCastFlags See also: ScriptVarCastFlags Implemented in acdk::lang::dmi::AcdkDmiClient, and acdk::lang::dmi::AcdkStdWeakTypeDmiClient.

virtual bool acdk::lang::dmi::DmiClient::provideMethodClazzInfo (   )  [inline, virtual]

return true if this object/class has ClazzInfo structures for static dispatching. true for standard ACDK objects, AAL. false for scripting clients, where matching arguments only can checked at invokation time.

void acdk::lang::dmi::DmiClient::setCurInvokeFlags (  int  flags  )  [static]

virtual int acdk::lang::dmi::DmiClient::typeDistance (  const ClazzInfo *  fromType, const ClazzInfo *  toType )  [pure virtual]

See also: int typeDistance(const ScriptVar& arg, const ClazzInfo* toType); Implemented in acdk::lang::dmi::AcdkDmiClient, and acdk::lang::dmi::AcdkStdWeakTypeDmiClient.

virtual int acdk::lang::dmi::DmiClient::typeDistance (  const ScriptVar &  arg, const ClazzInfo *  toType )  [pure virtual]

this method now returns the difference beetween the types. 0 for an exact match, -1 for incompatible types, various differences from 1 to 7 for compatible upcasts, from 257 to 263 for maybe compatible downcasts. > 300 for intepreted casts ( read int out of string convert to string) Implemented in acdk::lang::dmi::AcdkDmiClient, and acdk::lang::dmi::AcdkStdWeakTypeDmiClient.
