Receives the root of a CQL tree, creates a plan for the workflow layer, and returns the root of this plan

Specified by:

plan in interface Planner

Parameters:

root - - the CQL tree root

Returns:

the root of the plan for the workflow layer

Throws:

CQLTreeSyntaxException - - when the input tree is not in a valid state (this case is possible when a chain of proprocessors is applied sequentially, before planning)

CQLUnsupportedException
