Method Detail

splitCommandArgumentURLs

public static final java.net.URL[][] splitCommandArgumentURLs(java.net.URL[] arguments,
                                                              int maxArguments,
                                                              boolean usePaths)

Splits the given command arguments URLs such that they are suitable for separate command invocations. By splitting arguments in this way consumers can make use of the time in between running commands to perform updates to progress indication and check for user cancellation. It also helps to ensure that the command-line buffer limit (NT) is not exceeded.

Parameters:

arguments - the command argument URLs.

maxArguments - the maximum number of arguments in each resulting list. If this value is less than or equal to 0, no maximum is exercised.

usePaths - whether to split the command arguments URLs based on paths instead of filenames.

Returns:

the array of string lists, splitting original arguments.

createEnvironmentParams

public static final java.lang.String[] createEnvironmentParams(java.util.Map<java.lang.String,java.lang.String> envp)

Creates a string array specification of environment parameters. These may be supplied to a process runner in the setEnvironmentParams() method.

Parameters:

envp - a map of environment variable names and values.

Returns:

the string array specification of environment variables.

sendInputData

public static final void sendInputData(java.lang.Process process,
                                       java.lang.String data,
                                       boolean close)
                                throws java.io.IOException

Sends the given data as input to the process.

Parameters:

data - the data for writing to the process's output stream.

close - trueclose the input stream, false don't close the input stream.

Throws:

java.io.IOException - if an I/O error occurs.

sendInputData

public static final void sendInputData(java.lang.Process process,
                                       java.lang.String data)
                                throws java.io.IOException

Sends the given data as input to the process.

Parameters:

data - the data for writing to the process's output stream.

Throws:

java.io.IOException - if an I/O error occurs.
