~ReadCallback [destructor] [virtual] | Destroy the read callback. |
getReadBuffer [virtual] | It is possible that in some cases, getReadBuffer() may be called multiple times before readDataAvailable() is invoked. In this case, the data will be written to the buffer returned from the most recent call to readDataAvailable(). If the previous calls to readDataAvailable() returned different buffers, the ReadCallback is responsible for ensuring that they are not leaked. |
getReadBuffers [virtual] | It is possible that in some cases, getReadBuffers() may be called multiple times before readDataAvailable() is invoked. In this case, the data will be written to the buffer returned from the most recent call to readDataAvailable(). If the previous calls to readDataAvailable() returned different buffers, the ReadCallback is responsible for ensuring that they are not leaked. |
getReadMode | Return the current read mode. |
getZeroCopyFallbackBuffer [virtual] | Get a buffer to read data into when using zero-copy reads if some data cannot be read using a zero-copy page. |
isBufferMovable [virtual] | When data becomes available, isBufferMovable() will be invoked to figure out which API will be used, readBufferAvailable() or readDataAvailable(). If isBufferMovable() returns true, that means ReadCallback supports the IOBuf ownership transfer and readBufferAvailable() will be used. Otherwise, not. |
maxBufferSize [virtual] | Suggested buffer size, allocated for read operations, if callback is movable and supports folly::IOBuf |
readBufferAvailable [virtual] | readBufferAvailable() will be invoked when data has been successfully read. |
readDataAvailable [virtual] | readDataAvailable() will be invoked when data has been successfully read into the buffer(s) returned by the last call to getReadBuffer()/getReadBuffers() |
readEOF [virtual] | readEOF() will be invoked when the transport is closed. |
readErr [virtual] | readError() will be invoked if an error occurs reading from the transport. |
readZeroCopyDataAvailable [virtual] | readZeroCopyDataAvailable() will be called when data is available from a zero-copy read. |
readZeroCopyEnabled [virtual] | Return a ZeroCopyMemStore to use if the callback would like to enable zero-copy reads. Return nullptr to disable zero-copy reads. |
setReadMode | Set the read mode used to deliver data to this callback. |
