Functionality

The methods of this class enable you to use GZIP to compress binary data (X fields or XSTRINGS) portion by portion.

• CONSTRUCTOR

• SET_OUT_BUF

Makes an output buffer available.

• GZIP_BINARY_STREAM

Transfer of binary data to be compressed

• GZIP_BINARY_STREAM_END

Last transfer and completion of compression

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_GZIP_BINARY_HANDLER.

CLASS user_outbuf DEFINITION.
  PUBLIC SECTION.
    INTERFACES if_abap_gzip_binary_handler.
ENDCLASS.

CLASS user_outbuf IMPLEMENTATION.
