Constructor Detail

DoubleValue

public DoubleValue(Double dblNumber)

Constructs a DoubleValue object representing a double.

Parameters:

dblNumber - the double this DoubleValue should represent

DoubleValue

public DoubleValue(double dbl)

Constructs a DoubleValue object representing a double.

Parameters:

dbl - the double this DoubleValue should represent

Method Detail

valueOf

public static DoubleValue valueOf(String s)
                           throws ValueFormatException

Returns a new DoubleValue initialized to the value represented by the specified String.

Parameters:

s - the string to be parsed.

Returns:

a newly constructed DoubleValue representing the the specified value.

Throws:

ValueFormatException - If the String does not contain a parsable double.

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

The result is true if and only if the argument is not null and is a DoubleValue object that represents the same value as this object.

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Returns zero to satisfy the Object equals/hashCode contract. This class is mutable and not meant to be used as a hash key.

Returns:

always zero

Object.hashCode()

getInternalString

                            throws ValueFormatException

Returns the internal string representation of this value without modifying the value state.

Specified by:

getInternalString in class BaseValue

Returns:

the internal string representation

Throws:

ValueFormatException - if the value can not be represented as a String or if the value is null.
