Detailed Description

template<typename BindableNode>
class openvrml::node_impl_util::bound_node_stack< BindableNode >

A stack of bindable nodes.

The node at the top of the stack is considered the active node. Binding a node makes it the active node, moving it to the top of the stack if it already exists in the stack. Unbinding a node removes it from the stack, regardless of its position in the stack. See 4.6.10 of the VRML97 specification for further details of the semantics.

template<typename BindableNode>

bool openvrml::node_impl_util::bound_node_stack< BindableNode >::bind	(	BindableNode &	n,
		double	timestamp
	)			throw ( std::bad_alloc ) [inline]

Bind a node.

Call top()->bind(false). Push n onto the top of the stack, making it the active node. Call n.bind(true).

Postcondition:

top() == &n

Parameters:

[in,out]	n	the node to bind.
[in]	timestamp	the current time.

Exceptions:

std::bad_alloc

if memory allocation fails.

template<typename BindableNode>

bool openvrml::node_impl_util::bound_node_stack< BindableNode >::unbind	(	BindableNode &	n,
		double	timestamp
	)			throw ( std::bad_alloc ) [inline]

Unbind a node.

Call n.bind(false). Remove n from the top of the stack. The next node on the stack becomes the active node. Call top()->bind(true).

Postcondition:

&n is not on the stack.

Parameters:

[in,out]	n	the node to unbind.
[in]	timestamp	the current time.

Exceptions:

std::bad_alloc

if memory allocation fails.
