Method Detail

getYCoordForTime

public int getYCoordForTime(float time)

Getter for y-coordinate for given time. Y-coordinate either exactly the wanted (if time == some event time) or lineary interpolated from nearest y-coordinates for events.

Parameters:

time -

Returns:

y-coord for given time

getLinearYCoordForTime

public int getLinearYCoordForTime(float time)

Getter for linear y-coord for given time, i.e. the ratio time/total time is equal to the ratio y-coord / greatest y-coord.

Parameters:

time -

Returns:

y-coord for given time

getLastYCoord

public int getLastYCoord()

Getter for last y-coord in this layer.

Returns:

last y-coord

getFirstYCoord

public int getFirstYCoord()

Getter for first y-coord in this layer, normaly 0.

Returns:

firs y-coord

getTimeForYCoord

public float getTimeForYCoord(int yCoord)

Getter for time for given y-coord. Time is calculated vice versa as in getYCoordForTime.

Parameters:

value -

Returns:

time

getLinearTimeForYCoord

public float getLinearTimeForYCoord(int yCoord)

Getter for linear time for given y-coord. Time is calculated similary as in getLinearYCoordForTime.

Parameters:

yCoord -

Returns:

time

setMaxStepping

public void setMaxStepping(int maxStepping)

Setter for maximum stepping. Sets also maxGap to be greater than maxStepping. Re-calculates y-coordinates.

Parameters:

maxStepping -

setMinStepping

public void setMinStepping(int minStepping)

Setter for minimum stepping. Re-calculates y-coordinates.

Parameters:

minStepping -

setMaxGap

public void setMaxGap(int maxGap)

Setter for maximum gap. Re-calculates y-coordinates.

Parameters:

maxGap -
