8.217. Tie::Handle
Provides skeletal methods for
handle-tying classes. Tie::Handle provides a new
method as backup in case a class has no TIEHANDLE
method. (See the perltie manpage for more
detailed information and for examples.) To write your own tied-handle
classes, use the following methods.
| TIEHANDLE |
TIEHANDLE classname, list
Constructor. This method is invoked by the command
tie *glob,
classname. Associates new glob instance
with class classname.
list represents any additional arguments
needed to complete the association.
| DESTROY |
DESTROY this
Frees storage associated with the tied handle
this. Permits class to take some action
when an instance is destroyed. Rarely needed.
| GETC |
GETC this
Gets one character from tied handle this.
PRINT this, list
Prints the values in list.
| PRINTF |
PRINTF this, format, list
Prints the values in list using
format.
| READ |
READ this, scalar, length, offset
Reads length bytes from
scalar starting at
offset.
| READLINE |
READLINE this
Reads one line from this.
| WRITE |
WRITE this, scalar, length, offset
Writes length bytes of data from
scalar starting at
offset.
