Package java.util.regex

Class Summary

ASCII	Utility class that implements the standard C ctype functionality.
Matcher	An engine that performs match operations on a character sequence by interpreting a Pattern.
Pattern	A compiled representation of a regular expression.
Pattern.Add	An object added to the tree when a character class has an additional range added to it.
Pattern.All	Implements the Unicode category ALL and the dot metacharacter when in dotall mode.
Pattern.BackRef	Refers to a group in the regular expression.
Pattern.Begin	Node to anchor at the beginning of input.
Pattern.Behind	Zero width positive lookbehind.
Pattern.BitClass	Creates a bit vector for matching ASCII values.
Pattern.BnM	Attempts to match a slice in the input using the Boyer-Moore string matching algorithm.
Pattern.Both	An object added to the tree when a character class has another nested class in it.
Pattern.Bound	Handles word boundaries.
Pattern.Branch	Handles the branching of alternations.
Pattern.Caret	Node to anchor at the beginning of a line.
Pattern.Category	Node class that matches a Unicode category.
Pattern.CIBackRef
Pattern.CINotRange
Pattern.CIRange	Node class for matching characters within an explicit value range in a case insensitive manner.
Pattern.Conditional
Pattern.Ctype	Node class that matches a POSIX type.
Pattern.Curly	Handles the curly-brace style repetition with a specified minimum and maximum occurrences.
Pattern.Dollar	Node to anchor at the end of a line or the end of input based on the multiline mode.
Pattern.Dot	Node class for the dot metacharacter when dotall is not enabled.
Pattern.Dummy	Dummy node to assist in connecting branches.
Pattern.End	Node to anchor at the end of input.
Pattern.First	Searches until the next instance of its atom.
Pattern.GroupCurly	Handles the curly-brace style repetition with a specified minimum and maximum occurrences in deterministic cases.
Pattern.GroupHead	The GroupHead saves the location where the group begins in the locals and restores them when the match is done.
Pattern.GroupRef	Recursive reference to a group in the regular expression.
Pattern.GroupTail	The GroupTail handles the setting of group beginning and ending locations when groups are successfully matched.
Pattern.LastMatch	Node to match the location where the last match ended.
Pattern.LastNode
Pattern.LazyLoop	Handles the repetition count for a reluctant Curly.
Pattern.Loop	Handles the repetition count for a greedy Curly.
Pattern.Neg	Zero width negative lookahead.
Pattern.Node	Base class for all node classes.
Pattern.Not
Pattern.NotBehind	Zero width negative lookbehind.
Pattern.NotCtype
Pattern.NotRange
Pattern.NotSingle	Node class to match any character except a single char value.
Pattern.NotSingleA
Pattern.NotSingleU	Case independent unicode value.
Pattern.Pos	Zero width positive lookahead.
Pattern.Prolog	This sets up a loop to handle a recursive quantifier structure.
Pattern.Ques	The 0 or 1 quantifier.
Pattern.Range	Node class for matching characters within an explicit value range.
Pattern.Single	Node class for a single character value.
Pattern.SingleA	Case independent ASCII value.
Pattern.SingleU	Case independent unicode value.
Pattern.Slice	Node class for a case sensitive sequence of literal characters.
Pattern.SliceA	Node class for a case insensitive sequence of literal characters.
Pattern.SliceU	Node class for a case insensitive sequence of literal characters.
Pattern.Specials
Pattern.Start	Used for REs that can start anywhere within the input string.
Pattern.Sub	An object added to the tree when a character class has a range or single subtracted from it.
Pattern.TreeInfo	Used to accumulate information about a subtree of the object graph so that optimizations can be applied to the subtree.
Pattern.UnixCaret	Node to anchor at the beginning of a line when in unixdot mode.
Pattern.UnixDollar	Node to anchor at the end of a line or the end of input based on the multiline mode when in unix lines mode.
Pattern.UnixDot	Node class for the dot metacharacter when dotall is not enabled but UNIX_LINES is enabled.
