Method Detail

setWorkingDirectory

public static void setWorkingDirectory(java.io.File f)

Set the working temporary directory. This method can only be invoked when the singleton instance is uninitialized, and the File passed in must be both a directory and writable.

Parameters:

f - the temporary working directory

getTemporaryFile

public static java.io.File getTemporaryFile(java.lang.String handle)

Get a temporary file, if possible, and register it for cleanup later. In the event that a temporary file cannot be created, the method will attempt to create a file in the current working directory instead.

Parameters:

handle - a prefix to use in naming the file; probably only useful for debugging.

Returns:

the temporary file.

getTemporaryFile

public static java.io.File getTemporaryFile(java.lang.String handle,
                            java.io.File parent)

getTemporaryDirectory

public static java.io.File getTemporaryDirectory(java.lang.String handle)

Get a temporary working directory.

Parameters:

handle - a prefix to use in naming the directory.
