Constructor Detail

MutableDouble

public MutableDouble()

MutableDouble

public MutableDouble(double d)

Method Detail

set

public void set(double d)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Compares this object to the specified object. The result is true if and only if the argument is not null and is an MutableDouble object that contains the same double value as this object. Note that a MutableDouble isn't and can't be equal to an Double.

Overrides:

equals in class Object

Parameters:

obj - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(MutableDouble anotherMutableDouble)

Compares two MutableDouble objects numerically.

Parameters:

anotherMutableDouble - the MutableDouble to be compared.

Returns:

Tthe value 0 if this MutableDouble is equal to the argument MutableDouble; a value less than 0 if this MutableDouble is numerically less than the argument MutableDouble; and a value greater than 0 if this MutableDouble is numerically greater than the argument MutableDouble (signed comparison).

compareTo

public int compareTo(Object o)

Compares this MutableDouble object to another object. If the object is an MutableDouble, this function behaves like compareTo(MutableDouble). Otherwise, it throws a ClassCastException (as MutableDouble objects are only comparable to other MutableDouble objects).

Specified by:

compareTo in interface Comparable

Parameters:

o - the Object to be compared.

Returns:

0/-1/1

Throws:

ClassCastException - if the argument is not an MutableDouble.
