Functionality

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

• CONSTRUCTOR

• SET_OUT_BUF

Makes an output buffer available.

• GZIP_BINARY_STREAM

Transfer of binary data to be decompressed

• GZIP_BINARY_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_BINARY_HANDLER.

Example

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

CLASS user_outbuf IMPLEMENTATION.
  METHOD if_abap_ungzip_binary_handler~use_out_buf.
.... handle out buffer ...
  ENDMETHOD.
ENDCLASS.

DATA: uref       TYPE REF TO user_outbuf.

CREATE OBJECT uref.

CREATE OBJECT csref
   EXPORTING  CONVERSION      = 'DEFAULT'
              OUTPUT_HANDLER  = uref.

CALL METHOD  csref->decompress_binary_stream
   EXPORTING  GZIP_IN      = ingzip1 "some zipped binary
              GZIP_IN_LEN  = -1.

CALL METHOD  csref->decompress_binary_stream_end.
   EXPORTING  GZIP_IN      = ingzip2 "some more zipped binary
              GZIP_IN_LEN  = -1.
