Package org.ka2ddo.yaac.io

package org.ka2ddo.yaac.io

This package contains classes managing and controlling I/O operations between YAAC and the various sensors and communications devices the core distribution of YAAC can talk to. This includes:

• hardware and software TNCs (Terminal-Node Controllers, or radio modems)
• the APRS-IS Internet backbone
• GPS receivers
• weather stations
• inter-process communications with other data-providing applications

It also provides optimized variants of standard Java I/O classes to improve YAAC's CPU and memory heap performance.

CountingInputStream	InputStream to count the number of bytes read from the input, so as to drive a progress bar.
CountingInputStreamForSockets	InputStream to count the number of bytes read from the input, so as to drive a progress bar, but it avoids using the read() method of the passed-in InputStream, as SocketInputStream malloc's a 1-byte byte array for each such read, then throws the array away.
CountingOutputStream	This class is a FilterOutputStream that counts the number of bytes written to the lower-level OutputStream.
ExternalMessageSourceConnector	This implements a TCP or UDP socket or serial port reader for receiving ASCII-text messages to transmit to the RF and APRS-IS networks for APRS.
FileTNCConnector	This class implements a port to a TNC connected by an arbitrary file using KISS over asynchronous serial data.
GpsdConnector	This class provides a driver to connect YAAC to a gpsd daemon, so that YAAC can use a shared GPS receiver, or non-standard hardware that acts like a GPS receiver or speaks protocols other than NMEA 0183.

KissOverTcpConnector	This class defines the port driver for connecting to a KISS TNC over a TCP/IP network connection.
KissOverTcpConnector.FldigiModemChangeListener	Specify listener callback so YAAC can be informed of modem changes made at the fldigi UI.
MultiBufferedRandomAccessFile	This class provides a cached, buffered variant of RandomAccessFile, so that sequential reads from a starting point can be done with minimal JNI calls and actual kernel calls.
NeedsAppVersionInfoIfc	This interface tags a Connector that requires to be told its containing application's name and version.
NonshareableBufferedDataOutputStream	This class is a merged duplicate of java.io.BufferedOutputStream and java.io.DataOutputStream, except that its methods are not synchronized, limiting its use to a single thread.
NonshareableBufferedInputStream	This class is a copy of java.io.BufferedInputStream, but without the synchronization, which restricts instances of this class to use in a single thread.
NonshareableBufferedOutputStream	This class is a duplicate of java.io.BufferedOutputStream, except that its methods are not synchronized, limiting its use to a single thread.
NonshareableBufferedPrintStream	This class implements a non-mutexing buffered version of PrintStream, locked to the UTF-8 encoding, with no autoflushing.

NonshareableCountingBufferedOutputStream	This class is a duplicate of java.io.BufferedOutputStream, except that its methods are not synchronized, limiting its use to a single thread.
NonshareableDataInputStream	This class is a duplicate of java.io.DataInputStream, without the byte counter and the synchronization, so it can only be used by a single thread.
NonshareableDataInputStreamForSockets	This class is a duplicate of java.io.DataInputStream, without the byte counter and the synchronization, so it can only be used by a single thread, plus it avoids using the read() method of the passed-in InputStream, because SocketInputStream has the heap-thrashing habit of malloc-ing a 1-byte array for each such read and then throwing the array away.
NonshareableDataOutputStream	This class is a duplicate of java.io.DataOutputStream, without the byte counter and the synchronization, so it can only be used by a single thread.
ObjectEditorSettingsIfc	This interface permits an ObjectReportTransmitter to obtain extra information from an ObjectEditor that is not stored in the ObjectReport message.
ObjectReportSender	This class extends SendableMessageWrapper to cancel transmission when the ObjectReport is overridden by another source (i.e., taken over).
ObjectReportTransmitter	This interface defines a callback from the ObjectEditor, delivering an ObjectReport to be transmitted.

PortFailureReporterIfc	This interface declares the control methods of an abstract GUI object used by the I/O system to report an unsolicited port failure.
PortFailureReportListener	This interface defines a callback so a PortFailureReporterIfc implementer can tell the requestor that the GUI object no longer exists (user disposed of it) and should not be used any more.
