Instance Method Details

#encode(data) ⇒ String?

Performs encoding of the data, returning str, or nil if the encoder fails.

Returns:

  • (String, nil)

		output.clear();
		return str;
  	} else {
		return Qnil;
  	}
}

#format_flags=(Fixnum) ⇒ nil

By default, VCDiffEncoder uses standard VCDIFF format. This function

can be used before calling encode(), to specify that interleaved format
and/or checksum format should be used.

Returns:

  • (nil)

	Data_Get_Struct(self, open_vcdiff::VCDiffEncoder, encoder);

  	encoder->SetFormatFlags(FIX2INT(arg));
  	return Qnil;
}

#target_matching=(bool) ⇒ nil

By default, VCDiffEncoder looks for matches in the dictionary and also in the previously encoded target data. This function can be used before calling encode(), to specify whether or not target matching should be enabled.

Returns:

  • (nil)
