function fsgt_maxentr::fsgt_maxentr

(

in

o

)

Member Function Documentation

function irobj::do_get_html ( in  o )

protectedinherited

Abstract. HTML inner body.

function irobj::do_get_report ( in  o )

protectedinherited

Default report.

function irobj::extract_log ( in  o )

inherited

Parameters

o

Returns

[o, log]

function irobj::get_ancestry ( in  o, in  flag_title  )

inherited

Parameters

o
flag_title=1

function irobj::get_description ( in  o, in  flag_short  )

inherited

Returns description string

Precedence according with flag_short:

• 0: title > short > classtitle
• 1: short > title > classtitle

Parameters

flag_short=0

I am sealing this to make sure that no class will try to improvise on this function.

function irobj::get_html ( in  o, in  flag_stylesheet  )

inherited

Parameters

flag_stylesheet=1

Whether to include the stylesheet in the HTML

function irobj::get_methodname ( in  o, in  flag_short  )

inherited

This is used only to compose sequence string e.g. xxx->yyy->zzz

Parameters

flag_short=0

function irobj::get_params ( in  o, in  data  )

inherited

Calls Parameters GUI.

If flag_params, tries uip_<class>.m. If fails, tries uip_<ancestor>.m and so on

function irobj::get_report ( in  o )

inherited

Object reports are plain text. HTML would be cool but c'mon, we don't need that sophistication.

function irobj::setbatch ( in  o, in  params  )

inherited

Sets several properties of an object at once.

Parameters

o
params	Cell followint the pattern {'property1', value1, 'property2', value2, ...}
