### AbstractBean

    public AbstractBean()

Method Detail

### replaceVariables

    protected static java.lang.String replaceVariables(java.lang.String value)

  Replace all installer variables and localization keys in a string.

  Note: compiler variables are replaced at compile time.

  Parameters:
    `value` - the original string
  Returns:
    the string with all variables replaced.

### replaceVariables

    protected static java.lang.String replaceVariables(java.lang.String value,
                                                       ReplacementMode replacementMode)

  Replace all installer variables and localization keys in a string that should be used in a regular expression.

  Note: compiler variables are replaced at compile time.

  Parameters:
    `value` - the original string
    `replacementMode` - the replacement mode
  Returns:
    the string with all variables replaced.

### replaceVariables

    protected static java.io.File replaceVariables(java.io.File file)

  Replace all installer variables and localization keys in a file name.

  Note: compiler variables are replaced at compile time.

  Parameters:
    `file` - the original file
  Returns:
    the file with all variables replaced in its name.

### replaceVariables

    protected static java.lang.String[] replaceVariables(java.lang.String[] values)

  Replace all installer variables and localization keys in a string array. For array elements that consist of an installer variable that in turn contains an array value, the elements of that array value will be inserted into the returned array. For this reason the returned array may have more elements than the original array. For example, if the array passed in as an argument has the elements:

         [0] = "One"
         [1] = "${installer:myVariable}"
         [2] = "Three"

  and the variable `myVariable` has a String array value with the elements

         [0] = "Blue"
         [1] = "Green"

  then the returned array will be

         [0] = "One"
         [1] = "Blue"
         [2] = "Green"
         [3] = "Three"

  If the array in an installer variable is not of type `String[]`, each element will be converted to a string by calling `toString()` on it.``

  Note: compiler variables are replaced at compile time.

  Parameters:
    `values` - the original array
  Returns:
    the array with all variables replaced.
