org.apache.commons.lang.math .Range

All known Subclasses:   org.apache.commons.lang.math .NumberRange,  org.apache.commons.lang.math .IntRange,  org.apache.commons.lang.math .DoubleRange,  org.apache.commons.lang.math .FloatRange,  org.apache.commons.lang.math .LongRange,
Range
abstract public class Range (Code)

Range represents a range of numbers of the same type.

Specific subclasses hold the range values as different types. Each subclass should be immutable and java.io.Serializable Serializable if possible.

Method Detail
containsDouble
public boolean containsDouble(Number value)(Code)

Tests whether the specified Number occurs within this range using double comparison..

null is handled and returns false.

This implementation forwards to the Range.containsDouble(double) method.

Parameters:

containsDouble
public boolean containsDouble(double value)(Code)

Tests whether the specified double occurs within this range using double comparison.

This implementation uses the Range.getMinimumDouble() and Range.getMaximumDouble() methods and should be good for most uses.

Parameters:

containsFloat
public boolean containsFloat(float value)(Code)

Tests whether the specified float occurs within this range using float comparison.

This implementation uses the Range.getMinimumFloat() and Range.getMaximumFloat() methods and should be good for most uses.

Parameters:
  value - the float to test true if the specified number occurs within thisrange by float comparison

containsInteger
public boolean containsInteger(Number value)(Code)

Tests whether the specified Number occurs within this range using int comparison..

null is handled and returns false.

This implementation forwards to the Range.containsInteger(int) method.

Parameters:
  value - the integer to test, may be null true if the specified number occurs within thisrange by int comparison

containsInteger
public boolean containsInteger(int value)(Code)

Tests whether the specified int occurs within this range using int comparison.

This implementation uses the Range.getMinimumInteger() and Range.getMaximumInteger() methods and should be good for most uses.

Parameters:
