  +--com.braju.beta.lang.CharacterVariable

All Implemented Interfaces:

Variable

public final class CharacterVariable

extends java.lang.Object

implements Variable

Wraps a char and provides methods to convert the value to and from several datatypes [JDK1.0.2 compatible].

Field Summary

static int	ALIGN_CENTER When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the center.
static int	ALIGN_LEFT When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the left.
static int	ALIGN_RIGHT When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the right.
static int	LEADING_ZEROS When converting a character to a string with a specified minimum width, this constant says that the result should be filled up width leading zero, i.e.
static int	NO_FLAGS When converting a character to a string with specified minimum width, this constant says that the default format should be used [...].
static java.lang.Class	TYPE The class of this static object [...].

Constructor Summary

CharacterVariable()

CharacterVariable(char ch)
Wraps a character into an object just like java.lang.Character does, but provides some additional methods.

Method Summary

char	charValue() Get the character.
java.lang.Object	get()
static void	main(java.lang.String[] args)
static CharacterVariable[]	newArray(int length) Creates an array of length instance of this class.
void	set(char ch) Set a new value [...].
void	set(java.lang.Object o)
static java.lang.String	toEscapeString(char value) Convert a character into a readible escape-String, e.g.
static java.lang.String	toEscapeString(char value, int minWidth, int flags) Convert a character into a readible escape-String, e.g.
java.lang.String	toString() Return the wrapped character as a String.
static java.lang.String	toString(char ch) Convert a character into a string.
static java.lang.String	toString(char ch, int minWidth, int flags) Convert a character into a string with specified minimum width and alignment according to the flags-parameter [...].
static java.lang.String	toUTFString(char value) Convert a character into a readible UTF-String, e.g.
static java.lang.String	toUTFString(char value, int minWidth, int flags) Convert a character into a readible UTF-String, e.g.

Field Detail

NO_FLAGS

public static final int NO_FLAGS

When converting a character to a string with specified minimum width, this constant says that the default format should be used [...]. See also ALIGN_LEFT, ALIGN_CENTER and ALIGN_RIGHT.

ALIGN_LEFT

public static final int ALIGN_LEFT

When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the left.

ALIGN_CENTER

public static final int ALIGN_CENTER

When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the center.

ALIGN_RIGHT

public static final int ALIGN_RIGHT

When converting a character to a string with specified minimum width, this constant says that the result should be aligned to the right.

LEADING_ZEROS

public static final int LEADING_ZEROS

When converting a character to a string with a specified minimum width, this constant says that the result should be filled up width leading zero, i.e. no spaces.

TYPE

public static final java.lang.Class TYPE

The class of this static object [...]. Provides a convenient way to check or compare the type.

Constructor Detail

CharacterVariable

public CharacterVariable()

CharacterVariable

public CharacterVariable(char ch)

Wraps a character into an object just like java.lang.Character does, but provides some additional methods.

Method Detail

newArray

public static CharacterVariable[] newArray(int length)

Creates an array of length instance of this class.

set

public void set(char ch)

Set a new value [...]. This is better than creating a new object all the time.

set

public void set(java.lang.Object o)

Specified by:

set in interface Variable

get

public java.lang.Object get()

Specified by:

get in interface Variable

charValue

public char charValue()

Get the character.

toString

public static java.lang.String toString(char ch)

Convert a character into a string.

toString

public static java.lang.String toString(char ch,
                                        int minWidth,
                                        int flags)

Convert a character into a string with specified minimum width and alignment according to the flags-parameter [...]. Provides an easy way to align a boolean to the left, the right och to the center. If flags is given the value NO_FLAGS then the result is aligned to the left. By also specifing LEADING_ZEROS you can add '0's to left of the character.

toString

public java.lang.String toString()

Return the wrapped character as a String.

Overrides:

toString in class java.lang.Object

toUTFString

public static java.lang.String toUTFString(char value)

Convert a character into a readible UTF-String, e.g. "\\u0048".

toUTFString

public static java.lang.String toUTFString(char value,
                                           int minWidth,
                                           int flags)

Convert a character into a readible UTF-String, e.g. "\\u0048", with specified minimum width and alignment according to the flags-parameter [...]. Provides an easy way to align a string to the left, the right och to the center. If flags is given the value NO_FLAGS then the string is aligned to the left.

toEscapeString

public static java.lang.String toEscapeString(char value)

Convert a character into a readible escape-String, e.g. "\\n", with specified minimum width and alignment according to the flags-parameter [...]. Only '\\n', '\\r' and '\\t' are taken care of.

toEscapeString

public static java.lang.String toEscapeString(char value,
                                              int minWidth,
                                              int flags)

Convert a character into a readible escape-String, e.g. "\\n" [...]. Only '\\n', '\\r' and '\\t' are taken care of.
