Class FunctionTree

java.lang.Object
  org.teiid.query.function.FunctionTree

public class FunctionTree
extends java.lang.Object

Data structure used to store function signature information. There are multiple uses of this signature information so there are multiple data structures within the FunctionTree for handling each. One type of information is the function metadata required by users of this class for data driving GUIs or function selection. The other type of information is that needed to quickly find and/or invoke the functions at execution time. In general all methods are concerned with function metadata EXCEPT getFunction(java.lang.String, java.lang.Class[]) which is used to find a function for execution.
