Class TREXSequencedStringChecker

  • All Implemented Interfaces:
    ExpressionVisitor
    public class TREXSequencedStringChecker
extends Object
implements ExpressionVisitor
    makes sure that there is no sequenced string. "sequenced string" is something like this. <oneOrMore> <string> abc </string> </oneOrMore> Also, TREX prohibits sequence of typed strings and elements.

    In this checker, we introduce a function "f" that takes a string and computes the string-sensitivity of the pattern.

    "f" returns 3 bits of information. One is whether it contains elements. Another is whehter it contains text. And the last is whether it contains DataExp/ValueExp.

    "f" is computed recursively through the pattern.
