Compress (gb.compress)

This class allows Gambas to use compression algorithms, in order to compress files, strings in memory, and to write a compressed file using standard Stream methods.

Proprietà

Default	Returns default compression level for current compression driver.
Max	Returns the maximum compression level for the current compression driver. Of course you know, that the maximum compression means the slowest algorithm.
Min	Returns the minimum compression level for the current compression driver. Of course you know, that the minimum compression means the fastest algorithm.
Type	Before you can use any of the methods provided by this class, you have to select the compression driver to use.

Blocking	Returns or sets if the stream is blocking.
ByteOrder	Returns or sets the byte order used to read or write binary data to the stream.
EndOfFile	This property signals whether the last use of LINE INPUT reached the end of file, instead of reading a full line with an end-of-line character.
EndOfLine	Return or set the newline separator used by this stream.
Eof	Return if a stream reached its end.
Handle	Returns the system file descriptor associated with this Stream.
IsTerm	Return if a stream is associated with a terminal.
Lines	Returns a virtual object that allows you to enumerate a stream line by line.
NoShare
NullTerminatedString	Return or set if strings are null-terminated when they are serialized.
Tag	Returns or sets the tag associated with the stream.
Term	Return a virtual object that allows to manage the terminal associated with the stream.

Metodi

File	Once you have selected the compression driver, you can compress a file and place the result in another file using this method.
Open	Allows you to open a compressed file for reading. Prior to using this method, you have to select the appropiate compression driver.
String	This function returns a string compressed using the algorithm defined by the Type property.

Begin	Start to buffer data written to the stream, so that everything will be sent when the Send method is called.
Close	Closes the stream.
Drop	Drop the data that has been buffered since the last call to the Begin method.
ReadLine	Read a line of text from the stream, like the LINE INPUT instruction.
Send	Send all the data, in one shot, since the last call to Begin.
Watch	Start or stop watching the stream file descriptor for reading or writing, after it has been opened.
