Field Detail

printStream

private final java.io.PrintStream printStream

The print stream to write any events to.

Constructor Detail

StreamWriting

public StreamWriting(java.io.PrintStream printStream)

Creates a new stream writing listener.

Parameters:

printStream - The print stream to write any events to.

Method Detail

toSystemOut

public static AgentBuilder.RedefinitionStrategy.Listener toSystemOut()

Writes the stream result to System.out.

Returns:

An appropriate listener.

toSystemError

public static AgentBuilder.RedefinitionStrategy.Listener toSystemError()

Writes the stream result to System.err.

Returns:

An appropriate listener.

onBatch

public void onBatch(int index,
                    java.util.List<java.lang.Class<?>> batch,
                    java.util.List<java.lang.Class<?>> types)

Invoked before applying a batch.

Specified by:

onBatch in interface AgentBuilder.RedefinitionStrategy.Listener

Parameters:

index - A running index of the batch starting at 0.

batch - The types included in this batch.

types - All types included in the redefinition.

onError

public java.lang.Iterable<? extends java.util.List<java.lang.Class<?>>> onError(int index,
                                                                                java.util.List<java.lang.Class<?>> batch,
                                                                                java.lang.Throwable throwable,
                                                                                java.util.List<java.lang.Class<?>> types)

Invoked upon an error during a batch. This method is not invoked if the failure handler handled this error.

Specified by:

onError in interface AgentBuilder.RedefinitionStrategy.Listener

Parameters:

index - A running index of the batch starting at 0.

batch - The types included in this batch.

throwable - The throwable that caused this invocation.

types - All types included in the redefinition.

Returns:

A set of classes which should be attempted to be redefined. Typically, this should be a subset of the classes contained in batch but not all classes.

onComplete

public void onComplete(int amount,
                       java.util.List<java.lang.Class<?>> types,
                       java.util.Map<java.util.List<java.lang.Class<?>>,java.lang.Throwable> failures)

Invoked upon completion of all batches.

Specified by:

onComplete in interface AgentBuilder.RedefinitionStrategy.Listener

Parameters:

amount - The total amount of batches that were executed.

types - All types included in the redefinition.

failures - A mapping of batch types to their unhandled failures.
