Constructor Detail

CombinedNumericRange

public CombinedNumericRange()

Using this constructor relies on the user subsequently calling add() to add a range

Method Detail

add

public CombinedNumericRange add(Range<java.lang.Double> range)

Add a new range to this combined range. Notice this method returns this instance, so method calls can be chained together.

Parameters:

range - the new range to add

Returns:

this instance

lower

public java.lang.Double lower()

The lower value in the range; here, the same as minimum

Returns:

the smallest value of the range

upper

public java.lang.Double upper()

The upper value in the range; here, the same as maximum()

Returns:

the largest value of the range

adjust

public void adjust(java.lang.Double lower,
                   java.lang.Double upper)

Description copied from interface: Range

Adjusts the range.

Parameters:

lower - the new smallest value of the range

upper - the new largest value of the range

maximum

public double maximum()

Lazily calculates the maximum value in the range

Returns:

The numeric value of the largest value to include in the range.

minimum

public double minimum()

Lazily calculates the minimum value in the range

Returns:

the numeric value of the smallest value to include in the range.

contains

public boolean contains(java.lang.Double x)

This range contains some point iff one or more of its subranges contain that point

Returns:

a boolean to indicate whether the supplied point lies within the range

size

public double size()

Description copied from interface: Range

Compute the size of the range
