Detailed Description

Collects all MolecularFragments that are close enough to another molecular fragment. This processor examines the distances between every atom of a given fragment (further referred to as the reference fragment) and all other atoms in a molecular object he is applied to. If any atom of a fragment is closer to any atom of the reference fragment, the whole fragment is collected in an array.

The reference fragment itself is also contained in this array, if it is part of the molecular object the collector is applied to.

The array only contains pointers to the fragments, the fragments are neither changed, nor removed from the molecular object.

The reference fragment may either be given by a specialized constructor (also together with the distance) or using setFragment .

The fragment array is emptied prior to each collection run.
