Constructor Detail

MutableByte

public MutableByte()

Constructs a new MutableByte with the default value of zero.

MutableByte

public MutableByte(byte value)

Constructs a new MutableByte with the specified value.

Parameters:

value - a value.

MutableByte

public MutableByte(Number value)

Constructs a new MutableByte with the specified value.

Parameters:

value - a value.

Throws:

NullPointerException - if the object is null

Method Detail

getValue

public Object getValue()

Gets the value as a Byte instance.

Specified by:

getValue in interface Mutable

Returns:

the value as a Byte

setValue

public void setValue(byte value)

Sets the value.

Parameters:

value - the value to set

setValue

public void setValue(Object value)

Sets the value from any Number instance.

Specified by:

setValue in interface Mutable

Parameters:

value - the value to set

Throws:

NullPointerException - if the object is null

ClassCastException - if the type is not a Number

byteValue

public byte byteValue()

Returns the value of this MutableByte as a byte.

Returns:

the numeric value represented by this object after conversion to type byte.

intValue

public int intValue()

Returns the value of this MutableByte as a int.

Returns:

the numeric value represented by this object after conversion to type int.

longValue

public long longValue()

the numeric value represented by this object after conversion to type float.

doubleValue

public double doubleValue()

Returns the value of this MutableByte as a double.

Returns:

the numeric value represented by this object after conversion to type double.

equals

public boolean equals(Object obj)

Compares this object against the specified object. The result is true if and only if the argument is not null and is a MutableByte object that contains the same byte value as this object.

Parameters:

obj - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

hashCode

public int hashCode()

Returns a suitable hashcode for this mutable.

Returns:

a suitable hashcode

compareTo

public int compareTo(Object obj)

Compares this mutable to another in ascending order.

Specified by:

compareTo in interface Comparable

Parameters:

obj - the mutable to compare to

Returns:

negative if this is less, zero if equal, positive if greater

Throws:

ClassCastException - if the argument is not a MutableByte

toString

public String toString()

Returns the String value of this mutable.

Returns:

the mutable value as a string
