TSLLinkCmp Class Reference

Detailed Description

Base class for link comparator objects.

When clients wish to join two tiled networks together, they must provide a comparator object which defines both a sort order (through operator()), an is Equal() method which returns true when two links are the same and a make() method. The make() method is used to construct a link from segments which cross tile boundaries.

For example:

class MyLinkCmp : public TSLLinkCmp { virtual bool operator()(const TSLLink& link1, const TSLLink& link2) const { // Do whatever is appropriate return ???; } };

Member Function Documentation

isEqual()

virtual bool TSLLinkCmp::isEqual ( const TSLLink & link1, const TSLLink & link2 ) const

pure virtual

Compares two links.

Parameters

link1,link2

The two links.

Returns

true if link1 == link2, false otherwise.

make()

virtual TSLLink TSLLinkCmp::make ( const TSLLink * linkSegments[], int N ) const

pure virtual

Create one TSLLink object from the supplied TSLLink segments.

Parameters

linkSegments	An array of pointers to TSLLink segments.
N	The number of segments.

Returns

the composite Link object.

operator()()

virtual bool TSLLinkCmp::operator() ( const TSLLink & link1, const TSLLink & link2 ) const

pure virtual

Compares two links.

Parameters

link1,link2

The two nodes.

Returns

true if link1 < link2, false otherwise.
