public abstract class PacketReader : PacketIO, IPacketReader, IPacketIO, IDataIO, IBufferReader, IDataReader, IOffsetDataReader, IDataReferenceReader, IDisposable
The PacketReader type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PacketReader | Creates a new packet reader. |
Properties| Name | Description | |
|---|---|---|
 | BaseStream | Exposes access to the underlying stream (or null). Only returns a stream if the underlying data source is a Stream. |
| DataAvailable | Returns true if data is immediately available. (Specifically that EnsureAsync(1) won't block.) Returns true if there's any data remaining in the packet (this.Remaining > 0), or if the underlying stream has data available. Returning false does not necessarily mean that data is not available. It may be that it's not possible to detect data. |
| Endian |
Endianess for integral types.
(Inherited from PacketIO) |
| ID |
Optional ID to identify the packet (eg source/destination, packet section, etc).
(Inherited from PacketIO) |
| IsFixed |
Returns true if this is a fixed size packet. Ensure can't expand a fixed packet.
(Inherited from PacketIO) |
| Length |
Returns the current length of the packet.
(Overrides PacketIOLength) |
| Parent |
Returns the parent packet, or null.
(Inherited from PacketPosition) |
| Position |
Returns the current position in the packet.
(Overrides PacketIOPosition) |
| PositionInParent |
Returns the current position with respect to our parent packet.
(Inherited from PacketIO) |
| Remaining |
Returns the remaining data/space available in the packet. If it's a fixed-size packet, then this is definitive.
Otherwise Ensure can be used to try to extend the packet with more data/space.
(Overrides PacketIORemaining) |
| TextEncoding |
Encoding for text strings.
(Inherited from PacketIO) |
| Top |
Returns the top parent.
(Inherited from PacketIO) |
| ValidFrom | Returns the low water mark of the packet. Data prior to this mark may have been discarded and cannot be read. |
Methods| Name | Description | |
|---|---|---|
 | Advance |
Advances the current packet position. Implies Ensure(length).
(Inherited from PacketIO) |
| Close | Closes the current reader and closes access to the underlying stream. |
| Consume | Returns a new packet pointing to the next length bytes, and advances the current packet position. Implies Ensure(length). |
 | Create(ArraySegmentByte, Endian, BinaryTextEncoding, String) | Creates a fixed size PacketReader from a buffer of data. |
| Create(Byte, Endian, BinaryTextEncoding, String) | Creates a fixed size PacketReader from a buffer of data. |
| Create(PacketReaderPacketIOMethods, Endian, BinaryTextEncoding, String) | Creates a PacketReader. |
| Create(Stream, Endian, BinaryTextEncoding, String) | Creates a PacketReader from a stream of data. The underlying stream is left open when the PacketReader is closed. |
| Create(ArraySegmentByte, Int32, Int32, Endian, BinaryTextEncoding, String) | Creates a fixed size PacketReader from a buffer of data. |
| Create(Byte, Int32, Int32, Endian, BinaryTextEncoding, String) | Creates a fixed size PacketReader from a buffer of data. |
| Ensure |
Ensure that the next length bytes of data/space are available in the packet. If there isn't enough already
available, and the packet isn't fixed, then it'll attempt to read more data into or create more space in the packet.
(Inherited from PacketIO) |
| EnsureAsync | Ensure that the next length bytes of data is available in the packet. If there isn't enough already available, and the packet isn't fixed, then it'll attempt to read more data into the packet. |
| MarkPosition |
Return a position marker.
(Overrides PacketIOMarkPosition) |
| Peek | Returns a new packet pointing to the next length bytes, but does not advance the current packet position. Implies Ensure(length). |
| Prune | Declare that we'll not want to read length bytes again, allowing the packet to free memory. Advances ValidFrom by length bytes. |
Fields| Name | Description | |
|---|---|---|
 | length | The length of the packet. |
| position | The current position in the packet. |
| remaining | The number of bytes of data remaining in the packet. |
Extension Methods| Name | Description | |
|---|---|---|
 | Consume |
Returns a new data reader pointing to the next length bytes, and advances the current packet position.
