Member Function Documentation

begin() [1/2]

auto gobj::PathDir::begin ( ) ->path_iterator

overridevirtual

Returns

iterator to the beginning of the range

Implements gobj::PathNode.

Here is the caller graph for this function:

begin() [2/2]

auto gobj::PathDir::begin ( path_iterator begin, path_iterator end )->path_iterator

overridevirtual

Traverses the linked list of PathNode s to calculate the beginning of the range of GameObjects.

One of the main functions for calculating a path. Takes the left range, and applies whatever modifier the specific PathNode represents (filter by name, filter arbitrarily, get parent, get children, etc.) then gives it's range to the right (next) range, which continues the sequence. Once the end of the linked list is reached, an iterator to the beginning of the final range is returned.

Parameters

begin	the beginning of the parents ( or left ) range
end	sentinel iterator (past the end) of the parents ( left ) range

Returns

iterator to the beginning of the final iterators range

Implements gobj::PathNode.

Here is the call graph for this function:

checkForPtr()

auto gobj::PathDir::checkForPtr ( const GameObject * ptr, const std::shared_ptr< std::vector< GameObject * > > & siblings )->GameObject *

static

helper function to find next sibling of a GameObject

Parameters

ptr	GameObject to get next sibling of
siblings	shared pointer to vector of GameObject pointers that are siblings of ptr

Returns

the next sibling, or nullptr if at end of immediate range

Here is the caller graph for this function:

end() [1/2]

auto gobj::PathDir::end ( ) ->path_iterator

overridevirtual

Returns

iterator past the end of the range

Implements gobj::PathNode.

Here is the caller graph for this function:

end() [2/2]

auto gobj::PathDir::end ( path_iterator begin, path_iterator end )->path_iterator

overridevirtual

Traverses the linked list of PathNode s to find the proper end to the range of GameObjects.

Parameters

begin	beginning of parents ( or left ) range. Doesn't need to be the actual beginning, because end doesn't depend on beginning at all
end	end of parent ( or left ) range.

Returns

iterator to the end

Implements gobj::PathNode.

Here is the call graph for this function:

getNext()

auto gobj::PathDir::getNext ( GameObject * ptr ) ->GameObject *override

overridevirtual

Used by PathNode::path_iterator to increment.

Takes in a pointer to a GameObject, and returns the pointer to the next GameObject in the range.

Parameters

ptr	to a GameObject in the range of the PathNode

Returns

to a GameObject directly after ptr in the range

Implements gobj::PathNode.
