ListAccessor

public ListAccessor(List<P> list,
 DogLambdas.Copy<P> copier,
 Class<P> type)

Method Details

getTemp

public P getTemp(int index)

Description copied from interface: LArrayAccessor

Returns an instance of P which has the value of the element at 'index'. Note that the accessor will own the data type which is returned and can modify it on the next call.

This design is intended to be efficient when a massive array that's compressed and a very small array which is not compressed is used.

Specified by:

getTemp in interface LArrayAccessor<P>

 P dst)

Description copied from interface: LArrayAccessor
