equals()

template<class JClass_t >

virtual bool JLANG::JAbstractPointer< JClass_t >::equals ( const JAbstractPointer< JClass_t > &  object ) const

inlinevirtual

Equals.

The equality is evaluated by comparison of the internal pointers.

Parameters

object

abstract pointer

Returns

true if equals; else false

Definition at line 50 of file JAbstractPointer.hh.

    {
      return this->get() == object.get();
    }

get()

template<class JClass_t >

virtual JClass_t* JLANG::JAbstractPointer< JClass_t >::get ( ) const

pure virtual

Get pointer.

Returns

pointer to object

Implemented in JLANG::JPointer< JClass_t >, JLANG::JPointer< const JDAQTimeslice >, JLANG::JPointer< JChainReader< JClass_t > >, JLANG::JPointer< TObject >, JLANG::JPointer< const TFormula >, JLANG::JPointer< T >, JLANG::JPointer< JValue_t >, JLANG::JPointer< TTree >, JLANG::JMultiPointer< JTypeList< JHead_t, JTail_t > >, JLANG::JMultiPointer< JClass_t >, JLANG::JMultiPointer< JTail_t >, JLANG::JMultiPointer< JHead_t >, and JLANG::JMultiPointer< T >.

set()
