Base class for encapsulating system dependent stream capable objects
| ~Stream () | ~Stream | 
[virtual]
Destructor, terminates the stream
| inline int  error () | error | 
[const]
Get the error code of the last operation on this stream
Returns: Error code generated by the last operation on this stream
| bool  terminate () | terminate | 
[pure virtual]
Closes the stream
Returns: True if the stream was (already) closed, false if an error occured
| bool  canRetry () | canRetry | 
[const virtual]
Check if the last error code indicates a retryable condition
Returns: True if error was temporary and operation should be retried
| bool  valid () | valid | 
[const pure virtual]
Check if this stream is valid
Returns: True if the stream is valid, false if it's invalid or closed
| bool  setBlocking (bool block = true) | setBlocking | 
[virtual]
Set the blocking or non-blocking operation mode of the stream
Parameters:
| block | True if I/O operations should block, false for non-blocking | 
Returns: True if operation was successfull, false if an error occured
| int  writeData (const void* buffer, int length) | writeData | 
[pure virtual]
Write data to a connected stream
Parameters:
| buffer | Buffer for data transfer | 
| length | Length of the buffer | 
Returns: Number of bytes transferred, negative if an error occurred
| int  writeData (const char* str) | writeData | 
Write a C string to a connected stream
Parameters:
| str | String to send over the stream | 
Returns: Number of bytes transferred, negative if an error occurred
| inline int  writeData (const String& str) | writeData | 
Write a String to a connected stream
Parameters:
| str | String to send over the stream | 
Returns: Number of bytes transferred, negative if an error occurred
| inline int  writeData (const DataBlock& buf) | writeData | 
Write a Data block to a connected stream
Parameters:
| buf | DataBlock to send over the stream | 
Returns: Number of bytes transferred, negative if an error occurred
| int  readData (void* buffer, int length) | readData | 
[pure virtual]
Receive data from a connected stream
Parameters:
| buffer | Buffer for data transfer | 
| length | Length of the buffer | 
Returns: Number of bytes transferred, negative if an error occurred
| bool  allocPipe (Stream*& reader, Stream*& writer) | allocPipe | 
[static]
Allocate a new pair of unidirectionally pipe connected streams
Parameters:
| reader | Reference of a pointer receiving the newly allocated reading side of the pipe | 
| writer | Reference of a pointer receiving the newly allocated writing side of the pipe | 
Returns: True is the stream pipe was created successfully
| bool  allocPair (Stream*& str1, Stream*& str2) | allocPair | 
[static]
Allocate a new pair of bidirectionally connected streams
Parameters:
| str1 | Reference of a pointer receiving the newly allocated 1st end of the pair | 
| str2 | Reference of a pointer receiving the newly allocated 2nd end of the pair | 
Returns: True is the stream pair was created successfully
| bool  supportsPipes () | supportsPipes | 
[static]
Check if operating system supports unidirectional stream pairs
Returns: True if unidirectional pipes can be created
| bool  supportsPairs () | supportsPairs | 
[static]
Check if operating system supports bidirectional stream pairs
Returns: True if bidirectional pairs can be created
| inline  Stream () | Stream | 
[protected]
Default constructor
| inline void  clearError () | clearError | 
[protected]
Clear the last error code
| int m_error | m_error | 
[protected]
