static java.lang.String	evaluate(java.lang.String str, java.util.Properties props) This method manipulates a String by replacing occurrences of placeholders (in the form ${placeholder-name}) by specified values.
static java.lang.String	glue(java.lang.String[] arr, java.lang.String delim, int start, int end, boolean startWithDelim, boolean endWithDelim) This method creates a result String by concatenating a subarray of a String array, optionally separated by a delimiting String.

Method Detail

evaluate

public static java.lang.String evaluate(java.lang.String str,
                                        java.util.Properties props)

This method manipulates a String by replacing occurrences of placeholders (in the form ${placeholder-name}) by specified values. If a placeholder key has no specified value, it is not replaced by this method.

Parameters:

str - The source String to be manipulated

props - The key/value pairs with the keys equal to the placeholder names

Returns:

A String in which the occurrences of the placeholders in the source String have been replaced with the values specified by the property set

evaluate

public static java.lang.String evaluate(java.lang.String str)

This method manipulates a String by replacing occurrences of placeholders (in the form ${placeholder-name}) by values specified as System properties. If a placeholder key has no corresponding System property, its occurrences are not replaced by this method.

Parameters:

str - The source String to be manipulated

Returns:

A String in which the occurrences of the placeholders in the source String have been replaced with the values specified by the System properties

glue

public static java.lang.String glue(java.lang.String[] arr,
                                    java.lang.String delim,
                                    int start,
                                    int end,
                                    boolean startWithDelim,
                                    boolean endWithDelim)

This method creates a result String by concatenating a subarray of a String array, optionally separated by a delimiting String.

Parameters:

arr - The source String array

delim - The delimiter String

start - The starting index for the concatenation (inclusive)

end - The ending index for the concatenation (exclusive)

startWithDelim - Specifies whether or not the result String should begin with the delimiting String

endWithDelim - Specifies whether or not the result String should end with the delimiting String

Returns:

A String resulting from the concatenation of the specified array members, separated by the delimiting String
