SbeWriteBuffer

Grow

public static byte[] Grow(byte[] buffer, int minSize)

result = SbeWriteBuffer.Grow(buffer, minSize)

Returns a buffer at least bytes long. If the existing buffer is already large enough it is returned unchanged; otherwise a new buffer is allocated by doubling capacity until it covers , capped at MaxWriteBufferSize.

buffer

Current buffer (may be null).

minSize

Minimum required size in bytes.

Returns: A buffer whose length is at least .

IsOverflow

private static bool IsOverflow(Exception ex, int currentSize, int requiredSize)

result = SbeWriteBuffer.IsOverflow(ex, currentSize, requiredSize)

Recognizes the span-overflow exceptions thrown by the SBE serializer and computes a target size to grow to. A dedicated SbeBufferTooSmallException supplies an exact size; generic span overflows fall back to doubling.

Serialize

public static int Serialize(ClientSbeSession session, Func<SbeRecordSerializer, byte[], int> serialize)

result = SbeWriteBuffer.Serialize(session, serialize)

Serializes a message into the session write buffer, growing the buffer and retrying on overflow. Returns the number of bytes written. The (possibly reallocated) buffer is available via WriteBuffer.

session

Target session whose write buffer is used.

serialize

Serialize delegate: writes into the buffer, returns written length.

Returns: Number of bytes written into the session buffer.

InitialWriteBufferSize

public const int InitialWriteBufferSize

value = SbeWriteBuffer.InitialWriteBufferSize

Default initial size of a session write buffer.

MaxWriteBufferSize

public const int MaxWriteBufferSize

value = SbeWriteBuffer.MaxWriteBufferSize

Hard upper bound for a single SBE frame. A frame that does not fit even after growing to this size is treated as a genuine error and re-thrown, rather than looping forever on reallocation.
