getMethodBase ()

Returns the method base name.

setPerlBean (VALUE)

Set the PerlBean to which this attribute belongs. VALUE is the value. On error an exception Error::Simple is thrown.

VALUE must be a (sub)class of:

PerlBean

getPerlBean ()

Returns the PerlBean to which this attribute belongs.

setShortDescription (VALUE)

Set the attribute description. VALUE is the value. On error an exception Error::Simple is thrown.

getShortDescription ()

Returns the attribute description.

getPackage ()

Returns package name.

getPackageUS ()

Returns package name with :+ replaces by C <_>.

writeDefaultValue (FILEHANDLE)
