de.weAut.ClientPigpiod.CmdState

Enclosing class:

ClientPigpiod

public static final class ClientPigpiod.CmdState
extends Object

Status of a command executed.

One object of this class will be held per thread to hold the values of the current / last pigpiod IO command executed for the purpose of analysis or logging. As this is done on a per thread base there is no need to guard an [IO method + log method] pair be synchronised.

Field Detail

lastException

public Throwable lastException

Record form last pigpiod command.

If the last execution of ClientPigpiod.stdCmd(int, int, int) raised an exception it is caught and recorded here for subsequent logging or debugging. Otherwise the ClientPigpiod.stdCmd(int, int, int) sets lastException to null.
An exception can only happen in the course of the socket communication with the pigpiod daemon on the Pi.

lastCmd

public int lastCmd

Record form last pigpiod command.

The last execution of ClientPigpiod.stdCmd(int, int, int) records its parameters command, and its p1 and p2 parameter here for subsequent logging or debugging before the next execution of ClientPigpiod.stdCmd(int, int, int) directly or more often indirectly by one of the other IO commands.
The approach is not threadsafe. Applications with multiple control threads or cycles must not use these recorded informations in normal operation.

ClientPigpiod.logCommand(int), ClientPigpiod.debugCommand(int)

lastP1

public int lastP1

Record form last pigpiod command.

The last execution of ClientPigpiod.stdCmd(int, int, int) records its parameters command, and its p1 and p2 parameter here for subsequent logging or debugging before the next execution of ClientPigpiod.stdCmd(int, int, int) directly or more often indirectly by one of the other IO commands.
The approach is not threadsafe. Applications with multiple control threads or cycles must not use these recorded informations in normal operation.

lastP2

public int lastP2

Record form last pigpiod command.

The last execution of ClientPigpiod.stdCmd(int, int, int) records its parameters command, and its p1 and p2 parameter here for subsequent logging or debugging before the next execution of ClientPigpiod.stdCmd(int, int, int) directly or more often indirectly by one of the other IO commands.
The approach is not threadsafe. Applications with multiple control threads or cycles must not use these recorded informations in normal operation.

lastP3

public int lastP3

Record form last pigpiod command.

The last execution of ClientPigpiod.stdCmd(int, int, int) records its parameters command, and its p1 and p2 parameter here for subsequent logging or debugging before the next execution of ClientPigpiod.stdCmd(int, int, int) directly or more often indirectly by one of the other IO commands.
