ParsePropertiespublic ParseProperties(Project project, Collection<PropertyExpander> expanders, GetProperty getProperty) Constructor with a getProperty.- Parameters:
- project- the current Ant project.
- expanders- a sequence of expanders
- getProperty- property resolver.

Method Details- 
getProjectGet the project.- Specified by:
- getProjectin interface- ParseNextProperty
- Returns:
- the current Ant project.
 
- 
parsePropertiesDecode properties from a String representation.- This implementation starts parsing the valueparameter (unsurprisingly) at the beginning and asks eachPropertyExpanderwhether 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 nullthe method continues with the next PropertyExpander, otherwise it tries to look up the property's value using the configuredGetPropertyinstance.
- Once all PropertyExpanders have been consulted, the parse
  position is advanced by one character and the process repeated
  until valueis exhausted.
 If the entire contents of valueresolves to a single property, the looked up property value is returned. Otherwise a String is returned that concatenates the non-property parts ofvalueand the expanded values of the properties that have been found.- Parameters:
- value- The string to be scanned for property references. May be- null, in which case this method returns immediately with no effect.
- Returns:
- the original string with the properties replaced, or
         nullif the original string isnull.

containsPropertiesLearn whether a String contains replaceable properties.Uses the configured PropertyExpandersand scans through the string. Returns true as soon as any expander finds a property.- Parameters:
- value- the String to check.
- Returns:
- trueif- valuecontains property notation.
 
- 
parseNextPropertyReturn any property that can be parsed from the specified position in the specified String.Uses the configured PropertyExpandersandGetPropertyinstance .- Specified by:
- parseNextPropertyin interface- ParseNextProperty
- Parameters:
- value- String to parse
- pos- ParsePosition
- Returns:
- Object or null if no property is at the current location. If a property reference has been found but the property doesn't expand to a value, the property's name is returned.
