Constructor Detail
StringMatcher
public StringMatcher(String pattern, boolean ignoreCase, boolean ignoreWildCards)(Code)
StringMatcher constructor takes in a String object that is a simple pattern which may contain '*' for 0 and many characters and '?' for exactly one character. Literal '*' and '*' characters must be escaped in the pattern e.g. "\*" means literal "*", etc. Escaping any other character (including the escape character itself), just results in that character in the pattern. e.g. "\a" means "a" and "\\" means "\" If invoking the StringMatcher with string literals in Java, don't forget escape characters are represented by "\\".
Parameters:
  pattern - the pattern to match text against
Parameters:
  ignoreCase - if true, case is ignored
Parameters:
  ignoreWildCards - if true, wild cards and their escape sequences are ignored(everything is taken literally).




Method Detail
find
public StringMatcher.Position find(String text, int start, int end)(Code)
Find the first occurrence of the pattern between startend(exclusive).
Parameters:
  text - the String object to search in
Parameters:
  start - the starting index of the search range, inclusive
Parameters:
  end - the ending index of the search range, exclusive an StringMatcher.Position object that keeps the starting (inclusive) and ending positions (exclusive) of the first occurrence of the pattern in the specified range of the text; return null if not found or subtextis empty (start==end). A pair of zeros is returned if pattern is empty stringNote that for pattern like "*abc*" with leading and trailing stars, position of "abc"is returned. For a pattern like"*??*" in text "abcdf", (1,3) is returned



match
public boolean match(String text)(Code)
match the given text with the pattern true if matched eitherwise false
Parameters:
  text - a String object



match
public boolean match(String text, int start, int end)(Code)
Given the starting (inclusive) and the ending (exclusive) positions in the text, determine if the given substring matches with aPattern true if the specified portion of the text matches the pattern
Parameters:
  text - a String object that contains the substring to match
Parameters:
  start - marks the starting position (inclusive) of the substring
Parameters:
  end - marks the ending index (exclusive) of the substring



posIn
protected int posIn(String text, int start, int end)(Code)

Parameters:
  text - a string which contains no wildcard
Parameters:
  start - the starting index in the text for search, inclusive
Parameters:
  end - the stopping point of search, exclusive the starting index in the text of the pattern , or -1 if not found



regExpPosIn
protected int regExpPosIn(String text, int start, int end, String p)(Code)

Parameters:
  text - a simple regular expression that may only contain '?'(s)
Parameters:
  start - the starting index in the text for search, inclusive
Parameters:
  end - the stopping point of search, exclusive
Parameters:
  p - a simple regular expression that may contains '?' the starting index in the text of the pattern , or -1 if not found



regExpRegionMatches
protected boolean regExpRegionMatches(String text, int tStart, String p, int pStart, int plen)(Code)
boolean
Parameters:
  text - a String to match
Parameters:
  tStart - int that indicates the starting index of match, inclusive
Parameters:
  p - String, String, a simple regular expression that may contain '?'
Parameters:
  pStart -
Parameters:
  plen -



textPosIn
protected int textPosIn(String text, int start, int end, String p)(Code)

Parameters:
  text - the string to match
Parameters:
  start - the starting index in the text for search, inclusive
Parameters:
  end - the stopping point of search, exclusive
Parameters:
  p - a string that has no wildcard the starting index in the text of the pattern , or -1 if not found
