ANTLRFileStream Class |
This is a char buffer stream that is loaded from a file
all at once when you construct the object. This looks very
much like an ANTLReader or ANTLRInputStream, but it's a special case
since we know the exact size of the object to load. We can avoid lots
of data copying.

SyntaxThe ANTLRFileStream type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ANTLRFileStream(String) | Initializes a new instance of the ANTLRFileStream class |
| ANTLRFileStream(String, Encoding) | Initializes a new instance of the ANTLRFileStream class |
Properties| Name | Description | |
|---|---|---|
 | CharPositionInLine | (Inherited from ANTLRStringStream.) |
| Count | (Inherited from ANTLRStringStream.) |
| 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).
(Inherited from ANTLRStringStream.) |
| Line | (Inherited from ANTLRStringStream.) |
| SourceName | (Overrides ANTLRStringStreamSourceName.) |
Methods| Name | Description | |
|---|---|---|
| Consume | (Inherited from ANTLRStringStream.) |
| 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 | (Inherited from ANTLRStringStream.) |
| Load | |
| LT | (Inherited from ANTLRStringStream.) |
| Mark | (Inherited from ANTLRStringStream.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Release | (Inherited from ANTLRStringStream.) |
| 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.
(Inherited from ANTLRStringStream.) |
| Rewind | (Inherited from ANTLRStringStream.) |
| Rewind(Int32) | (Inherited from ANTLRStringStream.) |
| Seek |
consume() ahead until p==index; can't just set p=index as we must
update line and charPositionInLine.
(Inherited from ANTLRStringStream.) |
| Substring | (Inherited from ANTLRStringStream.) |
| ToString | (Inherited from ANTLRStringStream.) |
Fields| Name | Description | |
|---|---|---|
 | data | The data being scanned (Inherited from ANTLRStringStream.) |
| fileName | |
| lastMarker | Track the last mark() call result value for use in rewind(). (Inherited from ANTLRStringStream.) |
| markDepth | tracks how deep mark() calls are nested (Inherited from ANTLRStringStream.) |
| 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().
(Inherited from ANTLRStringStream.) |
| n | How many characters are actually in the buffer (Inherited from ANTLRStringStream.) |
 | name | What is name or source of this char stream? (Inherited from ANTLRStringStream.) |
| p | 0..n-1 index into string of next char (Inherited from ANTLRStringStream.) |
