System Classes for Converting Character Sets and Number Formats
The system classes described below enable the conversion of text data
between different code pages and of numeric
data between different number representations.
Among other things, these classes are a (possible) replacement for the
language elements TRANSLATE ... CODE PAGE ...
and TRANSLATE ... NUMBER FORMAT ... ,
the use of which is forbidden in Unicode
programs .
Data that is not available in ABAP format (that is, text data that is
not in the system code page format, or numerical data that is not in the
byte order used on the current
application server ) can be saved
in binary form in an x field or in an xstring .
When converting to ABAP format from another format, data is read from
a byte sequence and written to an ABAP data object.
When converting from ABAP format to another format, data is read from
an ABAP data object and written as a byte sequence.
This is done using the following classes:
CL_ABAP_CONV_IN_CE
Extracts other formats to ABAP data objects (reads a binary input
stream).
CL_ABAP_CONV_OUT_CE
Exports ABAP data objects to another format (writes to a binary output
stream).
CL_ABAP_CONV_X2X_CE
Extracts data from any format and exports data to any other format
(reads from a binary input stream and writes to a binary output stream).
Note
The class CL_ABAP_CODEPAGE wraps the
methods above to make it easier to handle code pages when processing
character and byte strings.
