Detailed Description

Function object to compare two node_interfaces based on their id.

node_interface_compare provides a Strict Weak Ordering for node_interfaces and ensures that exposedField definitions appropriately encroach on the namespace of eventIn and eventOut definitions. That is, per 4.7 of the VRML97 spec: “An exposedField named ‘zzz’ can be referred to as ‘set_zzz’ and treated as an eventIn, and can be referred to as ‘zzz_changed’ and treated as an eventOut.”

node_interface_compare is the comparator used by node_interface_set.

inline

Compare two node_interfaces based on their id.

Parameters

[in]	lhs	node_interface.
[in]	rhs	node_interface.

Returns

true if lhs.id is lexicographically less than rhs.id; false otherwise.
