Output streambuf using a client buffer and an overflow allocator.
Declared in <bdlsb_overflowmemoutstreambuf.h>
class OverflowMemOutStreamBuf
: public std::streambufThis class implements the output functionality of the bsl::basic_streambuf protocol, using client-supplied memory and client-supplied allocator if additional memory is needed.

| Name | Description |
|---|---|
OverflowMemOutStreamBuf [constructor] | Create an empty stream buffer with the specified initial output buffer. |
~OverflowMemOutStreamBuf [destructor] [virtual] | Destroy this stream buffer. |
dataLength | Return the number of bytes written to this stream. |
dataLengthInInitialBuffer | Return the length of data in the initial buffer, i.e., dataLength() if there is no overflow buffer, or initialBufferSize() if there is one. |
dataLengthInOverflowBuffer | Return the length of the data in the overflow buffer, i.e., 0 if there is no overflow buffer, or dataLength() - initialBufferSize() if there is one. |
initialBuffer | Return a pointer to the non-modifiable buffer supplied at construction. |
initialBufferSize | Return the size of the buffer supplied at construction. |
overflowBuffer | Return a pointer to the non-modifiable overflow buffer if there is one, or 0 otherwise. |
overflowBufferSize | Return the size of the overflow buffer, or 0 if there is no overflow buffer. |
operator BloombergLP::bslmf::NestedTraitDeclaration<OverflowMemOutStreamBuf, UsesBslmaAllocator> | Declare that this type uses a bslma allocator. |
| Name | Description |
|---|---|
overflow [virtual] | Put c at the next put position, growing the buffer if needed. |
seekoff [virtual] | Set the put position relative to the specified base and return it. |
seekpos [virtual] | Set the put position to the specified absolute position and return it. |
sync [virtual] | Update the cached data length from the current put position. |
xsputn [virtual] | Write characters from a buffer into this stream buffer. |
