edu.neu.ccs
Class XDouble

java.lang.Object
  edu.neu.ccs.XObject
      edu.neu.ccs.XNumber
          edu.neu.ccs.XDouble

All Implemented Interfaces:: Cloneable, Serializable, Stringable

Direct Known Subclasses:: HexXDouble

public class XDouble
extends XNumber

Object wrapper for the primitive double type that also provides Stringable capabilities.

The default value for this class is the double representation of zero.

As of 2.5.0, added methods isInfinite and isNaN in imitation of class Double, and also added methods isFinite to make the test for finiteness directly available to a caller.

Version:: 2.5.0
See Also:: Serialized Form

Field Summary

Constructor Summary
`XDouble()` Constructs a wrapper for the default `double` value.
`XDouble(double d)` Constructs a wrapper for the given `double` value.
`XDouble(String s)` Constructs a wrapper for the `double` value whose state information is encapsulated in the given `String` data.

Method Summary
`byte`	`byteValue()` Returns the value of this number as a `byte` value.
`double`	`doubleValue()` Returns the value of this number as a `double` value.
`boolean`	`equals(Object other)` Returns `true` if the wrapped object is equal to the given object, and `false` if it is not.
`float`	`floatValue()` Returns the value of this number as a `float` value.
`void`	`fromStringData(String data)` Sets the state of this object using information contained in the given `String`.
`double`	`getValue()` Returns the value wrapped by this object.
`int`	`hashCode()` Returns an `int` hash code appropriate for the wrapped object.
`int`	`intValue()` Returns the value of this number as a `int` value.
`boolean`	`isFinite()` Returns true if this XDouble is finite, that is, it is not positive or negative infinity nor is it NaN.
`static boolean`	`isFinite(double v)` Returns true if the given double is finite, that is, it is not positive or negative infinity nor is it NaN.
`boolean`	`isInfinite()` Returns true if this XDouble is either positive or negative infinity.
`static boolean`	`isInfinite(double v)` Returns true if the given double is either positive or negative infinity.
`boolean`	`isNaN()` Returns true if this XDouble is NaN, that is, "not a number".
`static boolean`	`isNaN(double v)` Returns true if the given double is NaN, that is, "not a number".
`long`	`longValue()` Returns the value of this number as a `long` value.
`static double`	`parseDouble(String s)` Parses a `double` value from a `String using the current shared parser.`
`void`	`setValue(double d)` Sets the value wrapped by this object to the given value.
`short`	`shortValue()` Returns the value of this number as a `short` value.
`static double[]`	`toPrimitiveArray(XDouble[] x)` Returns an array of primitive `double` values copied from the given array of `XDouble` objects.
`String`	`toString()` Returns a `String` representation of the wrapped value.
`String`	`toStringData()` Returns a `String` encapsulation of this object that contains information needed to set the state of this object at a later time.
`static XDouble[]`	`toXArray(double[] a)` Returns an array of `XDouble` objects initialized from the given array of `double` values.
