Method Detail

convertFromJavaString

public byte[] convertFromJavaString(java.lang.String sourceString)

Specified by:

convertFromJavaString in class CcsidManager

convertToJavaString

public java.lang.String convertToJavaString(byte[] sourceBytes)

Specified by:

convertToJavaString in class CcsidManager

convertToJavaString

public java.lang.String convertToJavaString(byte[] sourceBytes,
                                            int offset,
                                            int numToConvert)

Offset and numToConvert are given in terms of bytes! Not characters!

Specified by:

convertToJavaString in class CcsidManager

Parameters:

sourceBytes - An array of bytes to be converted.

offset - An offset indicating first byte to convert.

numToConvert - The number of bytes to be converted.

Returns:

A new Java String Object created after conversion.

convertFromJavaString

public void convertFromJavaString(java.lang.String sourceString,
                                  java.nio.ByteBuffer buffer)

Description copied from class: CcsidManager

Convert a Java String into bytes for a particular ccsid. The String is converted into a buffer provided by the caller.

Specified by:

convertFromJavaString in class CcsidManager

Parameters:

sourceString - A Java String to convert.

buffer - The buffer to convert the String into.

getByteLength

int getByteLength(java.lang.String str)

Description copied from class: CcsidManager

Returns the length in bytes for the String str using a particular ccsid.

Specified by:

getByteLength in class CcsidManager

Parameters:

str - The Java String from which to obtain the length.

Returns:

The length in bytes of the String str.
