Public Member Functions | |
| nothing | finishClose () |
| Call when the background operation is finished to wakeup PipeOutputStream::close(). | |
| int | peek () |
| Peeks the next byte available from the input stream; returns -1 if no more data available. | |
| *binary | read (int limit) |
| Reads bytes (up to a specified limit) from the input stream; returns NOTHING if there are no more bytes in the stream. | |
| nothing | reportError (hash ex) |
| Causes all operations on both pipe streams to wake up and throw an exception. | |

STREAM-THREAD-ERROR to be thrown, unless the stream is handed off to another thread using the StreamBase::unassignThread() method in the thread that currently owns the stream, and the StreamBase::reassignThread() method in the new thread.| int Qore::PipeInputStream::peek | ( | ) |
Peeks the next byte available from the input stream; returns -1 if no more data available.
Reads bytes (up to a specified limit) from the input stream; returns NOTHING if there are no more bytes in the stream.
| INPUT-STREAM-ERROR | limit is not positive |
| nothing Qore::PipeInputStream::reportError | ( | hash | ex | ) |
Causes all operations on both pipe streams to wake up and throw an exception.
Normally used from the background thread to report an error to the main thread.
| ex | the exception, must contain strings 'err' and 'desc' |
