Method Detail

start

public static ServerProcess start(org.wildfly.core.launcher.CommandBuilder commandBuilder)
                           throws IOException

Starts a server process based. The standard input, standard output and standard error streams will be inherited from the parent process.

Parameters:

commandBuilder - the command used to start the server

Returns:

the server process started

Throws:

IOException - if an error occurs starting the process

start

public static ServerProcess start(org.wildfly.core.launcher.CommandBuilder commandBuilder,
                                  Map<String,String> env)
                           throws IOException

Starts a server process based. The standard input, standard output and standard error streams will be inherited from the parent process.

Parameters:

commandBuilder - the command used to start the server

env - any environment variables to add to the server processes environment variables, can be null

Returns:

the server process started

Throws:

IOException - if an error occurs starting the process

start

public static ServerProcess start(org.wildfly.core.launcher.CommandBuilder commandBuilder,
                                  Map<String,String> env,
                                  OutputStream stdout)
                           throws IOException

Starts a server process based.

If the stdout parameter is not null both standard out and standard error will be redirected to to the output stream provided. If the parameter is null all standard streams will be inherited from the parent process.

Parameters:

commandBuilder - the command used to start the server

env - any environment variables to add to the server processes environment variables, can be null

stdout - the output stream used to consume standard out and standard error, can be null

Returns:

the server process started

Throws:

IOException - if an error occurs starting the process

getConsoleConsumer

public Thread getConsoleConsumer()

Returns the thread used to consume the standard output streams. If isInheritedStreams() returns false this will return null.

Returns:

the consumer thread or null if the processes inherits the streams from the parent process

isInheritedStreams

public boolean isInheritedStreams()

Returns true if the streams are inherited.

Returns:

true if the streams are inherited from the parent process, otherwise false
