hasNext()

template<class JInput_t , class JOutput_t >

virtual bool JLANG::JConversionIterator< JInput_t, JOutput_t >::hasNext ( )

inlineoverridevirtual

Check availability of next element.

Returns

true if the iteration has more elements; else false

Implements JLANG::JObjectIterator< JOutput_t >.

Definition at line 43 of file JConversionIterator.hh.

    {
      return in.hasNext();
    }

next()

template<class JInput_t , class JOutput_t >

virtual const pointer_type & JLANG::JConversionIterator< JInput_t, JOutput_t >::next ( )

inlineoverridevirtual

Get next element.

Returns

pointer to element

Implements JLANG::JObjectIterator< JOutput_t >.

Definition at line 54 of file JConversionIterator.hh.

    {
      const JInput_t* p = in.next();
 
      if (p != NULL)
        ps.reset(new JOutput_t(*p));  // type conversion
      else
        ps.reset(NULL);
 
      return ps;
    }

skip()

virtual skip_type JLANG::JObjectIterator< JOutput_t >::skip ( const skip_type ns )

inlinevirtualinherited

Skip items.

Parameters

ns	number of items to skip

Returns

number of items skipped

Definition at line 90 of file JObjectIterator.hh.

    {
      skip_type i = 0;
 
      for ( ; i != ns && hasNext(); ++i) {
        next();
