Detailed Description

Put a GEL or GELs in the WORLD's display list.

Questions:

Should this class be moved to a different header (since it is a concrete COMMAND rather than an abstract command)?

Member Function Documentation

bool COMMAND::clear (   )  [virtual, inherited]

After doit() and undoit() were called, restore things to the way they were before (may be a no-op for most derived classes). Reimplemented in UNDO_CMD, and MULTI_CMD. Definition at line 24 of file command.C. References COMMAND::_is_done, COMMAND::_is_undone, and COMMAND::is_done(). Referenced by MULTI_CMD::clear(), and UNDO_CMD::clear().

DISPLAY_CMD::DEFINE_RTTI_METHODS3 (  "DISPLAY_CMD"  , DISPLAY_CMD *  , COMMAND  , CCOMMAND *  )

COMMAND::DEFINE_RTTI_METHODS_BASE (  "COMMAND"  , CCOMMAND *  )  [inherited]

bool DISPLAY_CMD::doit (   )  [virtual]

Execute the command. Returns: true on success. If the command is already done, this is a no-op and still returns true. Reimplemented from COMMAND. Definition at line 67 of file command.C. References _gels, COMMAND::doit(), and ARRAY< T >::num().

void REFcounter::Free (   )  const [inline, inherited]

Definition at line 76 of file ref.H. References REFcounter::_mutex, REFcounter::_u, and REF_ME.

bool COMMAND::is_clear (   )  const [inline, inherited]

Neither doit() nor undoit() have been called. Definition at line 91 of file command.H. References COMMAND::_is_done, and COMMAND::_is_undone.

bool COMMAND::is_done (   )  const [inline, inherited]

doit() was called most recently. Definition at line 94 of file command.H. References COMMAND::_is_done. Referenced by COMMAND::clear().

bool COMMAND::is_undone (   )  const [inline, inherited]

undoit() was called most recently, after doit(). Definition at line 97 of file command.H. References COMMAND::_is_undone.

int REFcounter::Lock (   )  [inline, inherited]

Definition at line 105 of file ref.H. References REFcounter::_mutex, and REFcounter::_u. Referenced by REFlock::REFlock().

void REFcounter::Own (   )  const [inline, inherited]

Definition at line 59 of file ref.H. References REFcounter::_mutex, REFcounter::_u, and REF_ME.

virtual void DISPLAY_CMD::print (   )  const [inline, virtual]

Reimplemented from COMMAND. Definition at line 223 of file command.H. References _gels, and ARRAY< T >::num().

bool DISPLAY_CMD::undoit (   )  [virtual]

Undo the command. Returns: true on success. If the command is already undone, this is a no-op and still returns true. Reimplemented from COMMAND. Definition at line 76 of file command.C. References _gels, ARRAY< T >::num(), and COMMAND::undoit().

int REFcounter::Unique (   )  const [inline, inherited]

Definition at line 115 of file ref.H. References REFcounter::_mutex, and REFcounter::_u.

void REFcounter::Unlock (   )  [inline, inherited]
