/* Object initializer; sets up gdb-side structures for command.

Use: __init__(NAME, CMDCLASS, PARMCLASS, [ENUM])
|
||
|
||
NAME is the name of the parameter. It may consist of multiple
|
||
words, in which case the final word is the name of the new command,
|
||
and earlier words must be prefix commands.
|
||
|
||
CMDCLASS is the kind of command. It should be one of the COMMAND_*
|
||
constants defined in the gdb module.
|
||
|
||
PARMCLASS is the type of the parameter. It should be one of the
|
||
PARAM_* constants defined in the gdb module.
|
||
|
||
If PARMCLASS is PARAM_ENUM, then the final argument should be a
|
||
collection of strings. These strings are the valid values for this
|
||
parameter.
|
||
|
||
The documentation for the parameter is taken from the doc string
|
||
for the python class.
