InternalNode() [1/3]

gum::InternalNode::InternalNode

(

)

Default Constructor Creates an empty node with no variable attached.

Definition at line 41 of file internalNode.cpp.

References gum::Set< Key, Alloc >::emplace().

                             {
    GUM_CONSTRUCTOR(InternalNode);
    _nodeVar_ = nullptr;
  }

Here is the call graph for this function:

InternalNode() [2/3]

gum::InternalNode::InternalNode ( const DiscreteVariable *  v )

explicit

Class constructor.

Creates a node and attached the specified variable. Initializes the sons.

Definition at line 46 of file internalNode.cpp.

References gum::Set< Key, Alloc >::emplace().

                                                      {

  }

Here is the call graph for this function:

InternalNode() [3/3]

gum::InternalNode::InternalNode	(	const DiscreteVariable *	v,
		NodeId *	sons
	)

Constructor.

Creates a node and attached the specified variable. Also attached the given on map (and will handle it by itself especially deallocate it)

Warning

You'd better known what you're doing if you're using this one. sons must have the size of domainSize of v or the program will fail!
