Node for the BinarySearch or Decision Trees.

for the binary search tree, it basically consists of the EVENT, and pointers to the parent and daughters

in case of the Decision Tree, it specifies parent and daughters, as well as "which variable is used" in the selection of this node, including the respective cut value.
