详细描述

Class that handles text/warning/error printing for all objects in the system.

成员函数说明

add_object()

int add_object

(

vrpn_BaseClass *

o

)

Adds an object to the list of watched objects (multiple registration of the same object will result in only one printing for each message from the object). Returns 0 on success and -1 on failure. YOU MUST REMOVE any objects from a vrpn_TextPrinter that you create before destroying the printer if any connection objects survive, otherwise they may call a callback function on the destroyed object.

remove_object()

void remove_object

(

vrpn_BaseClass *

o

)

Remove an object from the list of watched objects (multiple deletions of the object will not cause any error condition; deletions of unregistered objects will not cause errors).

set_min_level_to_print()

void set_min_level_to_print	(	vrpn_TEXT_SEVERITY	severity,
		vrpn_uint32	level = 0 )

Change the level of printing for the object (sets the minimum level to print). Default is Warnings and Errors of all levels.

set_ostream_to_use()

void set_ostream_to_use

(

FILE *

o

)

Change the ostream that will be used to print messages. Setting a NULL ostream results in no printing.

text_message_handler()

static int VRPN_CALLBACK text_message_handler ( void * userdata, vrpn_HANDLERPARAM p )

staticprotected

Handles the text messages that come from the connections for objects we are watching.
