Method Detail

getVariables

public List<String> getVariables()

Parse function string to get the variables 1. Need this function at rule creation time (i.e when in BRMS) to insert the action part of the rules 2. Also need this at runtime to populate the HashMaps in the proposition which are used as tree leaf nodes in the AST.

Returns:

List of variables

getSymbols

public List<String> getSymbols()

Parse function string to get all the symbols. Need this only at rule creation time. Can't load the symbols in getVariables() because the AST removes the parenthesis and we need those. Get them from the string which has been validated in the constructor example A0*B4+(C*D)

Returns:

List of symbols
