Class WrappedEbcdicStringIterator

java.lang.Object
  com.ibm.etools.iseries.util.WrappedEbcdicStringIterator

All Implemented Interfaces:

IEbcdicStringIterator

public class WrappedEbcdicStringIterator
extends Object
implements IEbcdicStringIterator

This class allows you to split up a Unicode string into pieces of arbitrary lengths that are specified in EBCDIC byte lengths

Example

Take the following example where uppercase is Chinese and lower case is English aBCd in EBCDIC is [B1B2C1C2]d If we are wrapping this field on a 24x80 screen and the field begins at 75, we have room for 6 bytes on the first line. The first 5 bytes are a [B1B2 but this would not be valid without a closing shift. So we really want a (note the need to pad) and put the B1B1C1C2]d on the next line. If we would have used simple substring we would have gotten a [B1B2] and [C1C2]d which would have been wrong.

Nested Class Summary

static class	WrappedEbcdicStringIterator.WrappedEbcdicString Instance holding a string that corresponds to EBCDIC DBCS that is being truncated, one segment at a time.
static class	WrappedEbcdicStringIterator.WrappedEbcdicStringResult

Constructor Summary

WrappedEbcdicStringIterator(String unicodeString, int ccsid, boolean isPureDbcs)
Allow the given string to be split up into chunk based on EBCDIC byte lengths

Method Summary

IEbcdicString	getNextEbcdicBytes(int ebcdicByteLength) Return the String that corresponds to the next ebcdicByteLength number of EBCDIC bytes of the string iterated on by this class.
int	getRemainingLength() Return the EBCDIC byte length of the remainder

Constructor Detail

WrappedEbcdicStringIterator

public WrappedEbcdicStringIterator(String unicodeString,
                                   int ccsid,
                                   boolean isPureDbcs)

Allow the given string to be split up into chunk based on EBCDIC byte lengths

Parameters:

unicodeString - - the string to be split up

Method Detail

getNextEbcdicBytes

public IEbcdicString getNextEbcdicBytes(int ebcdicByteLength)

Return the String that corresponds to the next ebcdicByteLength number of EBCDIC bytes of the string iterated on by this class. Remove the Unicode characters that correspond the the first ebcdicByteLength number of ebcdic bytes. Return those characters.

Specified by:

getNextEbcdicBytes in interface IEbcdicStringIterator

Parameters:

ebcdicByteLength - - the desired length, in EBCDIC bytes, of the resultant string.

Returns:

getRemainingLength

public int getRemainingLength()

Return the EBCDIC byte length of the remainder

Specified by:

getRemainingLength in interface IEbcdicStringIterator

Returns:
