Interface PositionSequenceBuilder<P extends Position>

All Known Implementing Classes:

AbstractPositionSequenceBuilder, CountingPositionSequenceBuilder, FixedSizePositionSequenceBuilder, VariableSizePositionSequenceBuilder

public interface PositionSequenceBuilder<P extends Position>

A builder for PositionSequences.

PositionSequences are built by adding points in order.

Method Summary

Modifier and Type	Method and Description
PositionSequenceBuilder<P>	add(double... coordinates) Adds a Position to the PositionSequence being built.
PositionSequenceBuilder<P>	add(P position) Adds a Position to the PositionSequence being built.
int	getNumAdded() Returns the number of positions that have already been added.
PositionSequence<P>	toPositionSequence() Returns the result of this builder.
