Class Long

java.lang.Object
  ewe.data.DataObject
      ewe.sys.Long

All Implemented Interfaces:

Comparable, Copyable, DataUnit, Stringable, Value

public class Long

extends DataObject

implements Value

The ewe.sys.Long class was originally used to wrap java integral values instead of the standard java wrapper objects (java.lang.Integer, java.lang.Long, java.lang.Short, etc.)

Field Summary

static int	HEX This is an option for toString().
static Long	l1
static Long	l2
static Long	l3
static int	TRUNCATE This is an option for toString().
long	value
static int	ZERO_FILL This is an option for toString().

Constructor Summary

Long()

Method Summary

int	compareTo(Object other) Compare this object with another.
void	copyFrom(Object other) Copy all appropriate data from another object.
boolean	equals(Object other) Returns if this object is considered equal to the other object.
Long	fromJavaWrapper(Object javaWrapper) Place the value in the standard java Wrapper (e.g.
void	fromString(String str)
int	hashCode() Returns a hashCode for the object.
Long	set(long value)
Long	set(Long value)
String	toString() Return a String representation of this object.
String	toString(int length, int options) Convert to a String.

copyFrom

public void copyFrom(Object other)

Description copied from interface: DataUnit

Copy all appropriate data from another object.

Specified by:

copyFrom in interface DataUnit

Overrides:

copyFrom in class DataObject

toString

public String toString()

Description copied from class: Object

Return a String representation of this object.

Specified by:

toString in interface Stringable

Overrides:

toString in class Object

Returns:

a String representing this object.

compareTo

public int compareTo(Object other)

Description copied from interface: Comparable

Compare this object with another. It should return: less than 0 if this object is considered LESS than the "other" object; greater than 0 if this object is considered GREATER than the "other" object; 0 if this object is considered EQUAL to the "other" object. (i.e. it is an implicit subtraction).

Specified by:

compareTo in interface Comparable

Overrides:

compareTo in class DataObject

toString

public String toString(int length,
                       int options)

Convert to a String.

Parameters:

length - The length of the output String.

options - Can be a combination of HEX (output in hexadecimal), ZERO_FILL (left pad to length with zeros), TRUNCATE (truncate to be no longer than the specified length).

Returns:

The value converted to a String.

fromString

public void fromString(String str)

Specified by:

fromString in interface Stringable

equals

public boolean equals(Object other)

Description copied from class: Object

Returns if this object is considered equal to the other object.

Overrides:

equals in class DataObject

hashCode

public int hashCode()

Description copied from class: Object

Returns a hashCode for the object. The general contract of hashCode is:

An object must return the same hash code for its entire existence.

If two objects are considered equal by the equals() method, they should return the same hash code. Not all Objects will do this and you should only use hashCode() from Objects which declare an overrided version of hashCode(). The only Objects which provide consistent and correct hash codes under Ewe are Object, String and Class.

Overrides:

hashCode in class Object

fromJavaWrapper

public Long fromJavaWrapper(Object javaWrapper)
                     throws IllegalArgumentException

Place the value in the standard java Wrapper (e.g. java.lang.Integer, java.lang.Long, etc) into this ewe.sys.Long.

Parameters:

javaWrapper - one of the java.lang primitive wrapper values representing an integer type.

Returns:

this ewe.sys.Long after the value has been placed in it.

Throws:

IllegalArgumentException - if the javaWrapper parameter is not an integral or boolean value.
