parseProperties back to summary

parseProperties	back to summary
public Object parseProperties(String value) Decode properties from a String representation. This implementation starts parsing the `value` parameter (unsurprisingly) at the beginning and asks each `PropertyExpander` whether there is a property reference at that point. PropertyExpanders return the name of a property they may find and may advance the parse position. If the PropertyExpander returns `null` the method continues with the next PropertyExpander, otherwise it tries to look up the property's value using the configured `GetProperty` instance. Once all PropertyExpanders have been consulted, the parse position is advanced by one character and the process repeated until `value` is exhausted. If the entire contents of `value` resolves to a single property, the looked up property value is returned. Otherwise a String is returned that concatenates the non-property parts of `value` and the expanded values of the properties that have been found. Parameters value:String The string to be scanned for property references. May be `null`, in which case this method returns immediately with no effect. Returns:Object the original string with the properties replaced, or `null` if the original string is `null`.
