Interface | Description |
---|---|
PredicateDecorator |
Defines a predicate that decorates one or more other predicates.
|
Class | Description |
---|---|
AllPredicate |
Predicate implementation that returns true if all the
predicates return true.
|
AndPredicate |
Predicate implementation that returns true if both the predicates return true.
|
AnyPredicate |
Predicate implementation that returns true if any of the
predicates return true.
|
ChainedClosure |
Closure implementation that chains the specified closures together.
|
ChainedTransformer |
Transformer implementation that chains the specified transformers together.
|
CloneTransformer |
Transformer implementation that returns a clone of the input object.
|
ClosureTransformer |
Transformer implementation that calls a Closure using the input object
and then returns the input.
|
ConstantFactory |
Factory implementation that returns the same constant each time.
|
ConstantTransformer |
Transformer implementation that returns the same constant each time.
|
EqualPredicate |
Predicate implementation that returns true if the input is the same object
as the one stored in this predicate by equals.

|
FalsePredicate |
Predicate implementation that always returns false.
|
ForClosure |
Closure implementation that calls another closure n times, like a for loop.
|
IdentityPredicate |
Predicate implementation that returns true if the input is the same object
as the one stored in this predicate.
|
IfClosure |
Closure implementation acts as an if statement calling one or other closure
based on a predicate.
|
InstanceofPredicate |
Predicate implementation that returns true if the input is an instanceof
the type stored in this predicate.
|

Transformer implementation that creates a new object instance by reflection.
|
InvokerTransformer |
Transformer implementation that creates a new object instance by reflection.
|
MapTransformer |
Transformer implementation that returns the value held in a specified map
using the input parameter as a key.
|
NonePredicate |
Predicate implementation that returns true if none of the
predicates return true.
|
NOPClosure |
Closure implementation that does nothing.
|
NOPTransformer |
Transformer implementation that does nothing.
|
NotNullPredicate |
Predicate implementation that returns true if the input is not null.
|
NotPredicate |
Predicate implementation that returns the opposite of the decorated predicate.
|
NullIsExceptionPredicate |
Predicate implementation that throws an exception if the input is null.
|
NullIsFalsePredicate |
Predicate implementation that returns false if the input is null.
|
NullIsTruePredicate |
Predicate implementation that returns true if the input is null.
|
NullPredicate |
Predicate implementation that returns true if the input is null.
|
OnePredicate |
Predicate implementation that returns true if only one of the
predicates return true.
|
OrPredicate |
Predicate implementation that returns true if either of the predicates return true.
|
PredicateTransformer |
Transformer implementation that calls a Predicate using the input object
and then returns the input.
|
PrototypeFactory |
Factory implementation that creates a new instance each time based on a prototype.
|
StringValueTransformer |
Transformer implementation that returns the result of calling
String.valueOf on the input object. |
SwitchClosure |
Closure implementation calls the closure whose predicate returns true,
like a switch statement.
|
SwitchTransformer |
Transformer implementation calls the transformer whose predicate returns true,
like a switch statement.
|
TransformedPredicate |
Predicate implementation that transforms the given object before invoking
another
Predicate . |
TransformerClosure |
Closure implementation that calls a Transformer using the input object
and ignore the result.
|
TransformerPredicate |
Predicate implementation that returns the result of a transformer.
|
TruePredicate |
Predicate implementation that always returns true.
|
UniquePredicate |
Predicate implementation that returns true the first time an object is
passed into the predicate.
|
WhileClosure |
Closure implementation that executes a closure repeatedly until a condition is met,
like a do-while or while loop.

This package contains implementations of the
Closure
,
Predicate
,
Transformer
and
Factory
interfaces.
These provide simple callbacks for processing with collections.
WARNING: from v3.2.2 onwards this several classes in this package will
throw an UnsupportedOperationException
when trying to serialize or
de-serialize an instance to prevent potential remote code execution exploits.
Classes considered to be unsafe are:
In order to re-enable serialization support for these unsafe classes, the following system property can be used (via -Dproperty=true):
org.apache.commons.collections.enableUnsafeSerialization
Be warned though that enabling serialization support for these unsafe classes makes your application vulnerable to known exploits and you must ensure that your application does not de-serialize objects from untrusted sources.
