Detailed Description

Abstract class that must be inherited to define a custom dataset.

Member Function Documentation

virtual long long mknn::DatasetCustom::getNumObjects ( )

pure virtual

Return the current size of the dataset.

Returns

the number of objects stored in data_pointer

virtual void* mknn::DatasetCustom::getObject ( long long  pos )

pure virtual

Returns an object in the dataset.

Parameters

pos	the position of the desired object, between 0 and num_objects-1.

Returns

the object stored in the position pos in data_pointer

virtual void mknn::DatasetCustom::pushObject ( void *  object )

pure virtual

Adds an object to a dynamic dataset.

Note that the object must be added to the dataset through Dataset::pushObject method in order to the index knows that the dataset has changed and must be updated.

Parameters

object

the new object to add at the end of data_pointer.
