Member Function Documentation

bool TFNode::operator<

(

const TFNode &

node

)

Less-than comparison operator.

Allows for ordering of the nodes. One node is less than another if its x coordinate is lower.

Parameters:

node

The other node to compare this one with.

Returns:

true if this node's x-coordinate is lower than the other node's, false otherwise.
