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.

Esta clase hereda Stream en gb.

Esta clase es instanciable.

Esta clase actúa com un array estático de sólo lectura.

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.

Inherited properties
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.
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.

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.

Inherited methods
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.
