Constructor Detail

SMFTriangleTracker

public SMFTriangleTracker(SMFTriangleTracker.ErrorReceiverType inErrors,
                          long inVertexCount,
                          long inTriangleCount)

Construct a tracker.

Parameters:

inErrors - A receiver of errors

inVertexCount - The expected number of vertices

inTriangleCount - The expected number of triangles

Method Detail

addTriangle

public void addTriangle(com.io7m.jlexing.core.LexicalPosition<java.net.URI> lexical,
                        long v0,
                        long v1,
                        long v2)

Add a triangle.

Parameters:

lexical - The triangle declaration position

v0 - The index of vertex 0

v1 - The index of vertex 1

v2 - The index of vertex 2

check

public boolean check(com.io7m.jlexing.core.LexicalPosition<java.net.URI> lexical)

Check that all invariants hold. If they do not, errors will be published to the error receiver and false returned.

Parameters:

lexical - The lexical position

Returns:

true if all invariants hold
