Method Detail

getLength

public int getLength()

Description copied from class: Instruction

This method returns the length of an Instruction. The length of an instruction is defined by [the index of the first point of the next instruction] - [the index of the first point of this instruction].

In general this will just resolve to the size of the PointList, except for ViaInstruction and FinishInstruction, which are only virtual instructions, in a sense that they don't provide a turn instruction, but only an info ("reached via point or destination").

See #1216 and #1138
