method getSubExpression [line 2634]

string getSubExpression(
)

Returns the subexpression that is the immediate parent of the error portion.

For example, if the expression is 3+LN(MAX(4,)) then getInvalidPortionOfExpression() would return MAX(4,) and getSubExpression() would return LN(MAX(4,))

The returned sub expressions may not exactly match the original string supplied as the expression since space characters and paranthesis may be substituted for efficient parsing.
