Class AbstractInternationalString

Object
  AbstractInternationalString

All Implemented Interfaces:

CharSequence, Comparable<InternationalString>, InternationalString

Direct Known Subclasses:

GrowableInternationalString, ResourceInternationalString, SimpleInternationalString

public abstract class AbstractInternationalString
extends Object
implements InternationalString

A string that has been internationalized into several locales. This class is used as a replacement for the String type whenever an attribute needs to be internationalization capable. The default value (as returned by toString() and other CharSequence methods} is the string in the current system default.

The natural ordering is defined by the string in default locale, as returned by toString(). This string also defines the character sequence.

Since:

2.1

Method Summary

char	charAt(int index) Returns the character of the string in the default locale at the specified index.
int	compareTo(InternationalString object) Compares this string with the specified object for order.
int	length() Returns the length of the string in the default locale.
CharSequence	subSequence(int start, int end) Returns a subsequence of the string in the default locale.
String	toString() Returns this string in the default locale.
abstract String	toString(Locale locale) Returns this string in the given locale.

AbstractInternationalString

public AbstractInternationalString()

Constructs an international string.

Method Detail

length

public int length()

Returns the length of the string in the default locale. This is the length of the string returned by toString().

Specified by:

length in interface CharSequence

charAt

public char charAt(int index)
            throws IndexOutOfBoundsException

Returns the character of the string in the default locale at the specified index. This is the character of the string returned by toString().

Specified by:

charAt in interface CharSequence

Parameters:

index - The index of the character.

Returns:

The character at the specified index.

Throws:

IndexOutOfBoundsException - if the specified index is out of bounds.

subSequence

public CharSequence subSequence(int start,
                                int end)

Returns a subsequence of the string in the default locale. The subsequence is a String object starting with the character value at the specified index and ending with the character value at index end - 1.

Specified by:

subSequence in interface CharSequence

Parameters:

start - The start index, inclusive.

end - The end index, exclusive.

Returns:

The specified subsequence.

Throws:

IndexOutOfBoundsException - if start or end is out of range.

toString

public abstract String toString(Locale locale)

Returns this string in the given locale. If no string is available in the given locale, then some default locale is used. The default locale is implementation-dependent. It may or may not be the system default).

Specified by:

toString in interface InternationalString

Parameters:

locale - The desired locale for the string to be returned, or null for a string in the implementation default locale.

Returns:

The string in the given locale if available, or in the default locale otherwise.

toString

public String toString()

Returns this string in the default locale. Invoking this method is equivalent to invoking toString(Locale.getDefault()). All methods from CharSequence operate on this string. This string is also used as the criterion for natural ordering.

Specified by:

toString in interface CharSequence

Specified by:

toString in interface InternationalString

Overrides:

toString in class Object

Returns:

The string in the default locale.

compareTo

public int compareTo(InternationalString object)

Compares this string with the specified object for order. This method compare the string in the default locale, as returned by toString().

Specified by:

compareTo in interface Comparable<InternationalString>

Parameters:

object - The string to compare with this string.

Returns:

A negative number if this string is before the given string, a positive number if after, or 0 if equals.
