Detailed Description

a Source class that can pump from a device for a specified amount of time.

Definition at line 54 of file network.h.

Member Function Documentation

size_t NonblockingSource::GeneralPump2 ( lword &  byteCount,
bool  blockingOutput = true,
unsigned long  maxTime = INFINITE_TIME,
bool  checkDelimiter = false,
byte  delimiter = '\n' 
)

pump up to maxSize bytes using at most maxTime milliseconds

If checkDelimiter is true, pump up to delimiter, which itself is not extracted or pumped.

Definition at line 80 of file network.cpp.

size_t NonblockingSource::Pump2 ( lword &  byteCount,
bool  blocking = true 
)
inlinevirtual

Pump data to attached transformation.

Parameters
byteCountthe maximpum number of bytes to pump
blockingspecifies whether the object should block when processing input
Returns
the number of bytes that remain in the block (i.e., bytes not processed)

byteCount is an IN and OUT parameter. When the call is made, byteCount is the requested size of the pump. When the call returns, byteCount is the number of bytes that were pumped.

Implements Source.

Definition at line 77 of file network.h.

size_t NonblockingSource::PumpMessages2 ( unsigned int &  messageCount,
bool  blocking = true 
)
virtual

Pump messages to attached transformation.

Parameters
messageCountthe maximpum number of messages to pump
blockingspecifies whether the object should block when processing input

messageCount is an IN and OUT parameter.

Implements Source.
