ANTLRInputStream

Vacuum all input from a {@link Reader}/{@link InputStream} and then treat it like a {@code char[]} buffer. Can also pass in a {@link String} or {@code char[]} to use.

<p>If you need encoding, pass in stream/reader with correct encoding.</p>

Constructors

this this(): Undocumented in source.
this this(string input): @uml Copy data in string to a local char array
this this(char[] data, int numberOfActualCharsInArray): @uml This is the preferred constructor for strings as no data is copied
this this(File r): Undocumented in source.

Functions

LA int LA(int i): @uml @override
LT int LT(int i): Undocumented in source. Be warned that the author may not have intended to support it.
consume void consume(): @uml @override
getSourceName string getSourceName(): @uml @override
getText string getText(Interval interval): @uml @override
index int index(): @uml @override
load void load(File r, int size, int readChunkSize): Undocumented in source. Be warned that the author may not have intended to support it.
mark int mark(): @uml mark/release do nothing; we have entire buffer @override
release void release(int marker): @uml @override
reset void reset(): @uml 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.
seek void seek(int index): @uml consume() ahead until p==index; can't just set p=index as we must update line and charPositionInLine. If we seek backwards, just set p @override
size int size(): @uml @override
toString string toString(): @uml @override

Static variables

From CharStream

getText string getText(Interval interval): This method returns the text for a range of characters within this input stream. This method is guaranteed to not throw an exception if the specified {@code interval} lies entirely within a marked range. For more information about marked ranges, see {@link IntStream#mark}.
