FILTER objects represent arbitrary functions
defined by the user.

Part of:

package cl-ppcre, class regex

Direct Superclass

regex	The REGEX base class. All other classes inherit from this one.

Slot

fn	The user-defined function. Initargs::fn; Accessors:fn; Type:(or function symbol).
len	The length of the string. Initform:0; Accessors:len; Type:fixnum.

Direct Method

compute-min-rest	Returns the minimal length of REGEX plus CURRENT-MIN-REST. This is similar to REGEX-MIN-LENGTH ex...
compute-offsets	Returns the offset the following regex would have relative to START-POS or NIL if we can't comput...
copy-regex	Implements a deep copy of a REGEX object.
create-matcher-aux	Creates a closure which takes one parameter, START-POS, and tests whether REGEX can match *STRING...
regex-length	Return the length of REGEX if it is fixed, NIL otherwise.
regex-min-length	Returns the minimal length of REGEX.

Other Method

case-mode	Utility function used by the optimizer (see GATHER-STRINGS). Returns a keyword denoting the case-...
end-string-aux	Returns the constant string (if it exists) REGEX ends with wrapped into a STR object, otherwise N...
everythingp	Returns an EVERYTHING object if REGEX is equivalent to this object, otherwise NIL. So, “(.){1}” w...
flatten	Merges adjacent sequences and alternations, i.e. it transforms #<SEQ #<STR “a”> #<SEQ #<STR “b”> ...
gather-strings	Collects adjacent strings or characters into one string provided they have the same case mode. Th...
remove-registers	Returns a deep copy of a REGEX (see COPY-REGEX) and optionally removes embedded REGISTER objects ...
start-anchored-p	Returns T if REGEX starts with a “real” start anchor, i.e. one that's not in multi-line mode, NIL...
