Class CurriedClosure<V>
java.lang.Object
groovy.lang.GroovyObjectSupport
groovy.lang.Closure<V>
org.codehaus.groovy.runtime.CurriedClosure<V>
- All Implemented Interfaces:
- GroovyCallable<V>,- GroovyObject,- Serializable,- Cloneable,- Runnable,- Callable<V>
A wrapper for Closure to support currying. Normally used only internally
 through the 
curry(), rcurry() or
 ncurry() methods on Closure.
 Typical usages:
 // normal usage
 def unitAdder = { first, second, unit -> "${first + second} $unit" }
 assert unitAdder(10, 15, "minutes") == "25 minutes"
 assert unitAdder.curry(60)(15, "minutes") == "75 minutes"
 def minuteAdder = unitAdder.rcurry("minutes")
 assert minuteAdder(15, 60) == "75 minutes"
 // explicit creation
 import org.codehaus.groovy.runtime.CurriedClosure
 assert new CurriedClosure(unitAdder, 45)(15, "minutes") == "60 minutes"
 assert new CurriedClosure(unitAdder, "six", "ty")("minutes") == "sixty minutes"
 
 Notes:
 - Caters for Groovy's lazy (rcurry) and eager (ncurry) calculation of argument position

setDelegateDescription copied from class:ClosureAllows the delegate to be changed such as when performing markup building- Overrides:
- setDelegatein class- Closure<V>
- Parameters:
- delegate- the new delegate
 
- 
getDelegate- Overrides:
- getDelegatein class- Closure<V>
- Returns:
- the delegate Object to which method calls will go which is typically the outer class when the closure is constructed
 
- 
getOwner
-

- setResolveStrategyin class- Closure<V>
- Parameters:
- resolveStrategy- The resolve strategy to set
- See Also:

getParameterTypes- Overrides:
- getParameterTypesin class- Closure<V>
- Returns:
