Constructor Detail

Tool

public Tool()

Constructor. This is really only here to make this class a JavaBean to facilitate easy serializing; the Tool(String, String) constructor is preferred over this one.

Tool

public Tool(java.lang.String name,
            java.lang.String desc)

Constructor.

Parameters:

name - The name of this tool.

desc - A description of this tool. This may be null.

Method Detail

addArg

public void addArg(java.lang.String arg)

Adds a command line argument for this tool.

Parameters:

arg - The argument. This cannot be null.

See Also:

clearArgs(), setProgram(String)

checkForErrors

public java.lang.String checkForErrors()

Does basic checking to ensure that this program can run (the program exists, the directory to run in exists, etc.). Applications can call this method before running this tool as a sanity check, and to give nice error messages for common failure cases.

Returns:

A localized error message, or null if the program should be able to run.

See Also:

execute(ProcessRunnerOutputListener)

clearArgs

public void clearArgs()

Clears the command line arguments.

See Also:

addArg(String)

clearEnvVars

public void clearEnvVars()

Clears the environment variables associated with this tool. Note that if this tool is appending its environment to RText's environment, this does not clear the RText environment that is appended to; it only clears the environment variables to add.

See Also:

putEnvVar(String, String)

compareTo

public int compareTo(java.lang.Object o)

Compares this tool to another by name, lexicographically.

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

o - The other tool.

Returns:

The sort order of this tool, compared to another.

equals

public boolean equals(java.lang.Object o)

Returns whether this tool and another have the same name.

Returns:

Whether this tool and another have the same name.

execute

public void execute(ProcessRunnerOutputListener l)

Runs this tool in a separate thread.

Parameters:

l - Listens for events as this tool runs. This may be null.

See Also:

checkForErrors()

getAccelerator

public java.lang.String getAccelerator()

Returns the accelerator to use to activate this tool in a menu.

Returns:

The accelerator, or null if there is none.

See Also:

setAccelerator(String)

getAppendEnvironmentVars

public boolean getAppendEnvironmentVars()

Returns whether this tool should append any environment variables it defines to RText's current environment.

Returns:

Whether to append the environment variables defined. If this value is false, RText's environment is not appended.

See Also:

setAppendEnvironmentVars(boolean)

getArgs

public java.lang.String[] getArgs()

Returns the command line arguments for this Tool, as an array.

Returns:

An array of command line arguments, or an empty array if there are none.

See Also:

getDescription

public java.lang.String getDescription()

Returns a description of this tool.

Returns:

A description of this tool, or null if none is defined.

See Also:

setDescription(String)

getEnvVars

public java.util.Map getEnvVars()

Returns a copy of the environment variable map for this tool.

Returns:

The environment variables. This is a Map with both keys and values as Strings.

See Also:

getName

public java.lang.String getName()

Returns the name of this tool.

Returns:

The name of this tool.

See Also:
