All Implemented Interfaces:

Serializable

---

public final class NbProcessDescriptor

extends Object

implements Serializable

Encapsulates start information for a process. It allows the user to specify the process name to execute and arguments to provide. The progammer then uses method exec to start the process and can pass additional format that will be applied to arguments.

This allows to define arguments in format -user {USER_NAME} -do {ACTION} and then use MapFormat with defined values for USER_NAME and ACTION that will be substitued by into the arguments.

Constructor Detail

NbProcessDescriptor

public NbProcessDescriptor(String processName,
                           String arguments)

Create a new descriptor for the specified process, classpath switch, and classpath.

Parameters:

processName - the name of the executable to run

arguments - string for formating of arguments (may be quoted)

---

NbProcessDescriptor

public NbProcessDescriptor(String processName,
                           String arguments,
                           String info)

Create a new descriptor for the specified process, classpath switch, and classpath.

Parameters:

processName - the name of the executable to run

arguments - string for formating of arguments (may be quoted)

info - info how to format the arguments (human-readable string)

Method Detail

getProcessName

public String getProcessName()

Get the name of the executable to run.

Returns:

the name

---

getArguments

public String getArguments()

Getter the execution arguments of the process.

Returns:

the switch that the executable uses for passing the classpath as its command-line parameter

---

getInfo

public String getInfo()

Getter for the human readable info about the arguments.

Returns:

the info string or null

---

exec

public Process exec(Format format,
                    String[] envp,
                    File cwd)
             throws IOException

Executes the process with arguments formatted by the provided format. Also the envp properties are passed to the executed process, and a working directory may be supplied.

Parameters:

format - format to be applied to arguments, process and envp supplied by user. It can be null if no formatting should be done.

envp - list of properties to be applied to the process, or null to leave unspecified

cwd - the working directory to use, or null if this should not be specified

Returns:

handle to executed process.

Throws:

IOException - if the start of the process fails, or if setting the working directory is not supported

---

exec

public Process exec(Format format,
                    String[] envp,
                    boolean appendEnv,
                    File cwd)
             throws IOException

Executes the process with arguments, processName and envp formatted by the provided format. Also the envp properties are passed to the executed process, and a working directory may be supplied. Optionally the environment variables of the IDE may be appended to (replaced when there is overlap) instead of specifying all of the environment variables from scratch. This requires the IDE's launcher to translate environment variables to system properties prefixed by Env- in order to work correctly.

Parameters:

format - format to be applied to arguments, process and envp supplied by user. It can be null if no formatting should be done.

envp - list of properties to be applied to the process, or null to leave unspecified

appendEnv - if true and envp is not null, append or replace IDE's environment

cwd - the working directory to use, or null if this should not be specified

Returns:

handle to executed process.

Throws:

IOException - if the start of the process fails, or if setting the working directory is not supported

Since:
