Method Detail

size

public int size()

getStart

public double getStart()

getEnd

public double getEnd()

getStep

public double getStep()

getCoordinate

public double getCoordinate(int index)

Returns the coordinates of specified ticks. For the sake of performance, invokers need to ensure the index correct.

Parameters:

index - tick index

Returns:

getNormalizedCoordinate

public double getNormalizedCoordinate(int index)

Returns the normalized tick coordinates. that means the start point is always zero, and the array lines forward. For the sake of performance, invokers need to ensure the index correct.

Parameters:

index - tick index

Returns:

clone

public java.lang.Object clone()
