Detailed Description

The change_functor class is used to represent an abstract base class used to present object which look like callable functions which take a singe change::pointer argument.

Typically, this is used with the project_inventory_walk function to walk the changes of branch trees.

Constructor & Destructor Documentation

virtual change_functor::~change_functor

(

)

[virtual]

The destructor.

change_functor::change_functor	(	bool	include_branches,
		bool	all_changes = false
	)		[protected]

The constructor. May ony be called by a derived class.

change_functor::change_functor

(

change_functor::change_functor

(

)

[private]

The default constructor. Do not use.

Member Function Documentation

bool change_functor::all_changes

(

)

const [inline]

The all_changes method is used to determine whether or not the functor should be invoked for incomplete changes as well as completed changes and branches.

Definition at line 63 of file functor.h.

virtual time_t change_functor::earliest

(

)

[virtual]

The earliest method is used to determine the earliest time of interest to the functor.

Returns:

time_t; the default implementation returns zero.

bool change_functor::include_branches

(

)

const [inline]

The include_branches method is sued to determine whether or not the functor should also be invoked for branches, when performing a recursive descent.

Definition at line 56 of file functor.h.

virtual time_t change_functor::latest

(

)

[virtual]

The lastest method is used to determine the latest time of interest to the functor.

Returns:

time_t; the default implementation returns "now".

virtual void change_functor::operator()

(

change::pointer

cp

)

[pure virtual]

The operator() method is used to call the functor.

Parameters:

cp	The change to be operated upon.

Implemented in change_functor_inventory, change_functor_archive, change_functor_inventory_builder, change_functor_pending_printer, change_functor_attribute_list, change_functor_file_find, change_functor_inventory_list, change_functor_date_version, change_functor_versions, change_functor_debcloses, and change_functor_debchangelog.

change_functor& change_functor::operator=

(

const change_functor &

)

[protected]

The assignment operator. May ony be called by a derived class.

virtual bool change_functor::recurse_branches

(

)

[virtual]

The recurse_branches method may be used to determine whether to recurse into nested branches or not.

Returns:

bool; true if recursion is desired, false if not. The default implementation returns true.
