All Implemented Interfaces:

Runnable, Handler

public class TclRePollHandler
extends RePollHandler

Post-process all "polled" properties with tcl code. The following server properties are used:

script

The name of the TCL script to call at each request. The interpreter is created with the following global variables. The script is "evaluted" once on startup.

• prefix The handler prefix
• server The current server instance
• logLevel The current server log level setting
• argv0 The name of the running script

The tcl procedure "process" is called with the java properties object. Any modifications to that object are done here.

debug

If set, the "script" is sourced each time.

public TclRePollHandler()

Method Detail

init

public boolean init(Server server,
                    String prefix)

Create a tcl interp, extract the properties, and run the init script

Specified by:

init in interface Handler

Overrides:

init in class RePollHandler

Parameters:

server - The HTTP server that created this Handler. Typical Handlers will use Server.props to obtain run-time configuration information.

prefix - The handlers name. The string this Handler may prepend to all of the keys that it uses to extract configuration information from Server.props. This is set (by the Server and ChainHandler) to help avoid configuration parameter namespace collisions.

Returns:

true if this Handler initialized successfully, false otherwise. If false is returned, this Handler should not be used.

fillProps

public void fillProps(Properties props,
                      HttpRequest target)
               throws IOException

Fill the properties from the input stream

Overrides:

fillProps in class RePollHandler

Throws:

IOException
