Detailed Description

 KJavaProcess ()

KJavaProcess

Creates a process object, the process is NOT invoked at this point. You should first set the process's parameters, and then call startJava.

 ~KJavaProcess ()

~KJavaProcess

[virtual]

bool  startJava ()

startJava

Invoke the JVM with the parameters that have been set. The Java process will start after this call.

void  stopJava ()

stopJava

Stop the JVM (if it's running).

bool  isRunning ()

isRunning

Returns the status of the java Process- true if it's ok, false if it has died. It calls KProcess::isRunning()

void  setJVMPath ( const QString& path )

setJVMPath

Used to specify the path to the Java executable to be run.

void  setClasspath ( const QString& classpath )

setClasspath

This will set the classpath the Java process will use. It's used as a the -cp command line option. It adds every jar file stored in $KDEDIRS/share/apps/kjava/ to the classpath, and then adds the $CLASSPATH environmental variable. This allows users to simply drop the JSSE (Java Secure Sockets Extension classes into that directory without having to modify the jvm configuration files.

void  setSystemProperty ( const QString& name, const QString& value )

setSystemProperty

Set a property on the java command line as -Dname=value, or -Dname if value is QString::null. For example, you could call setSystemProperty( "kjas.debug", "" ) to set the kjas.debug property.

void  setMainClass ( const QString& clazzName )

setMainClass

The class to be called when startJava() is called.

void  setExtraArgs ( const QString& args )

setExtraArgs

Extra flags passed to the JVM.

void  setClassArgs ( const QString& classArgs )

setClassArgs

Arguments passed to the main class. They will be very last in the java command line, after the main class.

void  send ( char cmd_code, const QStringList& args )

send

Sends a command to the KJAS Applet Server by building a QByteArray out of the data, and then writes it standard out.

void  send ( char cmd_code, const QStringList& args, const QByteArray& data )

send

Sends a command to the KJAS Applet Server by building a QByteArray out of the data, and then writes it standard out. It adds each QString in the arg list, and then adds the data array.

void  slotWroteData ()

slotWroteData

[protected slots slot]

This slot is called whenever something is written to stdin of the process. It's called again to make sure we keep emptying out the buffer that contains the messages we need send.

void  slotReceivedData ( int, int& )

slotReceivedData

[protected slots slot]

This slot is called when the Java Process writes to standard out. We then process the data from the file descriptor that is passed to us and send the command to the AppletServer

bool  invokeJVM ()

invokeJVM

[protected virtual]

void  killJVM ()

killJVM

[protected virtual]

QByteArray*  addArgs ( char cmd_code, const QStringList& args )

addArgs

[protected]

void  popBuffer ()

popBuffer

[protected]

void  sendBuffer ( QByteArray* buff )

sendBuffer

[protected]

void  storeSize ( QByteArray* buff )

storeSize

[protected]

KProcess* javaProcess

javaProcess

[protected]

void  received ( const QByteArray& )

received
