  • match

    public static boolean match(int min,
     int max,
     java.lang.Object default_val,
     java.lang.Object obj,
     java.lang.Object[] vars,

  • match

    public static java.lang.Object[] match(int min,
     int max,
     java.lang.Object default_val,
     java.lang.Object obj)

    Succeeds if obj is a list of length [min..max].

    Parameters:

    obj - the object to match against

    Returns:

    true iff the match succeeded On success, max_length values from the elements of the list are placed in vars (starting at start_vars); if obj is shorter, missing elements are set to default_value.

  • match

    public boolean match(java.lang.Object obj,
     java.lang.Object[] vars,
     int start_vars)

    Succeeds if obj is a list of length [min_length..max_length].

    Specified by:

    match in class Pattern

    Parameters:

    obj - the object to match against

    vars - the "pattern variable" values extracted from obj go here

    start_vars - where in vars to strt putting the varCount() values

    Returns:

    null on failure, or an array of bound pattern variables: max_length values from the elements of the list are placed in the result; if obj is shorter, missing elements are set to default_value.

  • varCount

    public int varCount()

    Specified by:

    varCount in class Pattern

  • print

    public void print(Consumer out)
