ANTLRStringStream Class

A pretty quick CharStream that pulls all data from an array directly. Every method call counts in the lexer. Java's strings aren't very good so I'm avoiding.

Copy

[SerializableAttribute]
public class ANTLRStringStream : ICharStream, 
	IIntStream

<SerializableAttribute>
Public Class ANTLRStringStream
	Implements ICharStream, IIntStream

The ANTLRStringStream type exposes the following members.

Constructors

	Name	Description
	ANTLRStringStream	Initializes a new instance of the ANTLRStringStream class
	ANTLRStringStream(String)	Copy data in string to a local char array
	ANTLRStringStream(Char, Int32)	This is the preferred constructor as no data is copied
	ANTLRStringStream(String, String)	Initializes a new instance of the ANTLRStringStream class
	ANTLRStringStream(Char, Int32, String)	Initializes a new instance of the ANTLRStringStream class

Properties

	Name	Description
	CharPositionInLine
	Count
	Index	Return the current input symbol index 0..n where n indicates the last symbol has been read. The index is the index of char to be returned from LA(1).
	Line
	SourceName

Methods

	Name	Description
	Consume
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	LA
	LT
	Mark
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Release
	Reset	Reset the stream so that it's in the same state it was when the object was created except the data array is not touched.
	Rewind
	Rewind(Int32)
	Seek	consume() ahead until p==index; can't just set p=index as we must update line and charPositionInLine.
	Substring
	ToString	(Overrides ObjectToString.)

Fields

	Name	Description
	data	The data being scanned
	lastMarker	Track the last mark() call result value for use in rewind().
	markDepth	tracks how deep mark() calls are nested
	markers	A list of CharStreamState objects that tracks the stream state values line, charPositionInLine, and p that can change as you move through the input stream. Indexed from 1..markDepth. A null is kept @ index 0. Create upon first call to mark().
	n	How many characters are actually in the buffer
	name	What is name or source of this char stream?
	p	0..n-1 index into string of next char
