Class ParallelBuffer is a simple I/O stream utility that intercepts output from an ostream and redirects the output as necessary for parallel I/O. This class defines a stream buffer class for an ostream class.
| enum AMP::ParallelStreamBuffer::StreamOutputType : uint8_t |
|
explicit |
Create a parallel buffer class. The object will require further initialization to set up the I/O streams and prefix string.
| type | Output type |
|
virtual |
The destructor simply deallocates any internal data buffers. It does not modify the output streams.
|
override |
Write an overflow character into the parallel buffer (called from streambuf).
|
inlineprivate |
| void AMP::ParallelStreamBuffer::reset | ( | ) |
Clear the internal buffer's memory
| void AMP::ParallelStreamBuffer::setOutputStream | ( | std::ofstream * | stream | ) |
Set the output file stream
| stream | Output stream |
| void AMP::ParallelStreamBuffer::setOutputType | ( | StreamOutputType | type | ) |
Set the output stream type
| type | Output type |
|
override |
Synchronize the parallel buffer (called from streambuf).
|
override |
Read an overflow character from the parallel buffer (called from streambuf). This is not implemented. It is needed by the MSVC++ stream implementation.
|
override |
Write the specified number of characters into the output stream (called from streambuf).
