Class BoundedInterval

java.lang.Object

bdv.util.BoundedInterval

public class BoundedInterval
extends Object

A interval consisting of BoundedValue minimum and maximum that can span any interval in a given range. The UI can listen to changes by adding listeners can attach to the minimum and maximum values and/or overriding the updateInterval(int, int) method.

Field Detail

minIntervalSize

protected final int minIntervalSize

minimum interval size. max - min >= minIntervalSize.

Constructor Detail

BoundedInterval

public BoundedInterval(int rangeMin,
                       int rangeMax,
                       int initialMin,
                       int initialMax,
                       int minIntervalSize)

Parameters:

rangeMin - lower bound of the allowed range. the interval minimum cannot be lower than this.

rangeMax - upper bound of the allowed range. the interval maximum cannot be lower than this.

initialMin - initial interval minimum.

initialMax - initial interval maximum.

minIntervalSize - interval is forced to have this size at least, i.e., max - min >= minIntervalSize.

Method Detail

updateInterval

protected void updateInterval(int min,
                              int max)

This is called when the min or max values change. The default implementation does nothing but derived classes can use it to trigger UI updates, etc.

Parameters:

min - the new minimum of the interval

max - the new maximum of the interval

getMinBoundedValue

public BoundedValue getMinBoundedValue()

Get the current minimum of the interval.

Returns:

the current minimum of the interval.

getMaxBoundedValue

public BoundedValue getMaxBoundedValue()

Get the current maximum of the interval.

Returns:

the current maximum of the interval.

getRangeMin

public int getRangeMin()

Get the current minimum of the allowed range. (The interval ( getMinBoundedValue(), getMaxBoundedValue()) is be a non-empty interval within the allowed range.)

Returns:

the current minimum of the allowed range.

getRangeMax

public int getRangeMax()

Get the current maximum of the allowed range. (The interval ( getMinBoundedValue(), getMaxBoundedValue()) is be a non-empty interval within the allowed range.)

Returns:

the current maximum of the allowed range.

setRange

public void setRange(int min,
                     int max)

Set the allowed range. The interval (getMinBoundedValue(), getMaxBoundedValue()) is enforced to be a non-empty interval within the allowed range.

Parameters:

min - minimum of the allowed range.

max - maximum of the allowed range.
