public class InvokerTransformer<I,O> extends java.lang.Object implements Transformer<I,O>, java.io.Serializable
WARNING: This class will throw an
UnsupportedOperationException
when trying to serialize or
de-serialize an instance to prevent potential remote code execution exploits.
In order to re-enable serialization support for InvokerTransformer
the following system property can be used (via -Dproperty=true):
org.apache.commons.collections.enableUnsafeSerialization

de-serialization (see COLLECTIONS-580).
|
O |
transform(java.lang.Object input)
Transforms the input to result by invoking a method on the input.
|
private void |
writeObject(java.io.ObjectOutputStream os)
