Functionality

The methods of this class enable you to decompress texts (in X fields or XSTRINGS) compressed using GZIP portion by portion.

• CONSTRUCTOR

• SET_OUT_BUF

Makes an output buffer available

• UNGZIP_TEXT_STREAM

Transfer of text segments to be decompressed

• UNGZIP_TEXT_STREAM_END

Last transfer and completion of decompression

When the output buffer is filled, a callback method is called. This method must implement the method use_out_buf of the interface IF_ABAP_UNGZIP_TEXT_HANDLER.
