Methods


isLocalCharDBCSLeadByte

public native static boolean isLocalCharDBCSLeadByte(byte local);

Checks whether a local-codepage character is a lead byte for DBCS systems. This can only return true if the local codepage is a DBCS codepage.

Return Value:

Returns true or false.

ParameterDescription
local Local codepage character to be checked.


LocalStringToJavaString

String LocalStringToJavaString( String local )

Converts a string from a local codepage to Unicode.

Return Value:

Returns the Unicode representation of the string.

ParameterDescription
local Local codepage string to be converted.

Remarks:

Java internally uses the Unicode encoding system. Unfortunately, this means more than just using 16-bits per character in the local codepage. For example, character (149) in the Microsoft® Windows® codepage used in America (codepage 1252) is a bullet character. This is not true on the Macintosh and many Unix systems. If you try to hard-code this value in Windows, the bullet will not appear correctly on other platforms.


LocalStringToJavaString

public static char[] LocalStringToJavaString( byte B[] )

Converts a byte array from a local codepage to a Unicode-filled character array.

Return Value:

Returns the Unicode representation of the array.

ParameterDescription
B Local codepage string to be converted.


LocalStringToJavaString

public static char[] LocalStringToJavaString( char B[] )

Converts a character array from a local codepage to a Unicode-filled character array. Java internally uses the Unicode encoding system.

Return Value:

Returns the Unicode representation of the array.

ParameterDescription
B Local codepage string to be converted.


LocalStringToJavaString

public static char[] LocalStringToJavaString( byte B[], int off, int len )

Converts a segment of a byte array from a local codepage to a Unicode-filled array.

Return Value:

Returns the Unicode representation of the array.

ParameterDescription
B Local codepage string containing the segment to be converted.
off Starting point of the segment to be converted.
len Length of the segment to be converted.


LocalStringToJavaString

public static char[] LocalStringToJavaString( char B[], int off, int len )

Converts a segment of a character array from a local codepage to a Unicode-filled character array.

Return Value:

Returns the Unicode representation of the array.

ParameterDescription
B Local codepage string containing the segment to be converted.
off Starting point of the segment to be converted.
len Length of the segment to be converted.


LocalStringToJavaString

public static char LocalStringToJavaString( byte local )

Converts a byte from a local codepage to a Unicode character array.

Return Value:

Returns the Unicode representation of the array.

ParameterDescription
local Local codepage string to be converted.


JavaStringToLocalString

public static byte JavaStringToLocalString( char Uni )

Converts a Java character to a character in the local codepage.

Return Value:

Returns the local codepage character.

ParameterDescription
Uni Java character to be converted.


JavaStringToLocalString

public static byte[] JavaStringToLocalString( char C[] )

Converts a Java character array to a byte array in the local codepage.

Return Value:

Returns the local representation of the array.

ParameterDescription
C Java character string to be converted.


JavaStringToLocalString

public static byte[] JavaStringToLocalString( char C[], int off, int len )

Converts a Java character array to a byte array in the local codepage.

Return Value:

Returns the local representation of the array.

ParameterDescription
C Java character string to be converted.
off Starting point of the segment to be converted.
len Length of the segment to be converted.


getNumKeyboardLanguages

int getNumKeyboardLanguages()

Retrieves the number of active keyboard languages in the system.

Return Value:

Returns the number of active keyboard languages.


getKeyboardLanguages

int getKeyboardLanguages(int array[])

Retrieves a list of the keyboard languages currently active in the system.

Return Value:

Returns the number of active languages.

ParameterDescription
array Array to receive a list of keyboard language identifiers. Each identifier can be one of the LANG_ and SUBLANG_ field values.


getKeyboardLanguages

public static int [] getKeyboardLanguages()

Retrieves a list of the keyboard languages currently active in the system.

Return Value:

Returns an array containing the active languages.


getKeyboardLanguage

int getKeyboardLanguage()

Gets the currently active keyboard language.

Return Value:

Returns a value matching one of the LANG_ or SUBLANG_ fields.


getKeyboardLanguageName

public static String getKeyboardLanguageName(int id)

Retrieves the keyboard language name.

Return Value:

Returns the name of the language.

ParameterDescription
id Identifier of the language.


setKeyboardLanguage

boolean setKeyboardLanguage( Applet App, int idLanguage )

Sets a new active keyboard language.

Return Value:

True if the action was successful, false otherwise.

ParameterDescription
App The Applet to set the language for.
idLanguage Identifier of the language to activate. Can be one of the LANG_ and SUBLANG_ field values.
