Method Detail

• centreWithin

  public static java.awt.Point centreWithin(java.awt.Rectangle rec,
                                            java.awt.Dimension dim)

  rec - the bounding rectangle of the parent.

  dim - the dimensions of the child.

  Returns:

  the X and Y coordinates the child should have.

• copyFile

  public static void copyFile(java.io.File inputFile,
                              java.io.File outputFile)
                       throws java.io.IOException

  Copies the contents of any disk file to a specified output file. If the output file is a relative path, it is made absolute against the directory of the input file. The output file will be overwritten if it exist. A CRC32 check is performed to compare source and copy after the copy process and if results negative a StreamCorruptedException is thrown. Function reports errors to System.err.

  Parameters:

  inputFile - a File object

  outputFile - a File object

  Throws:

  java.io.IOException - if the function could not be completed because of an IO or CRC check error

• ensureFilePath

  public static boolean ensureFilePath(java.io.File file,
                                       java.io.File defaultDir)

  Ensures the existence of the directory which may be part of the path specification of parameter file. If the specified file is a relative path, it is made absolute against defaultDir. If defaultDir is null the System property "user.dir" is assumed as default directory.

  Returns:

  true if and only if the parent directory of the specified file exists after this function terminates

• ensureDirectory

  public static boolean ensureDirectory(java.io.File dir,
                                        java.io.File defaultDir)

  Ensures the existence of the directory specified by the parameter. If the directory does not exist, an attempt is performed to create it including all necessary parent directories that may be implied by the specification.

  Parameters:

  dir - File specifying the intended directory; if the specified path is a relative path, it is made absolute against defaultDir. If defaultDir is null the System directory "user.dir" is assumed as default.

  Returns:

  true if and only if the specified file exists and is a directory after this function terminates

• textVariance

  public static int textVariance(char[] ca)

• deleteDir

  public static boolean deleteDir(java.io.File dir)

  Deletes all files and subdirectories under dir. Returns true if all deletions were successful. If a deletion fails, the method stops attempting to delete and returns false.
