Constructor Detail

Collector

protected Collector(AgentBuilder.RawMatcher matcher,
                    AgentBuilder.PoolStrategy poolStrategy,
                    AgentBuilder.LocationStrategy locationStrategy,

                    AgentBuilder.FallbackStrategy fallbackStrategy,
                    AgentBuilder.CircularityLock circularityLock)

Creates a new collector.

Parameters:

matcher - The matcher to identify what types to redefine.

poolStrategy - The pool strategy to use.

locationStrategy - The location strategy to use.

descriptionStrategy - The description strategy for resolving type descriptions for types.

listener - The listener to notify on transformations.

fallbackStrategy - The fallback strategy to apply.

circularityLock - The circularity lock to use.

Method Detail

consider

protected void consider(Class<?> type,
                        boolean modifiable)

Considers a loaded class for collection.

Parameters:

type - The loaded type being considered.

modifiable - true if the considered type is considered modifiable.

apply

protected int apply(Instrumentation instrumentation,
                    AgentBuilder.RedefinitionStrategy.BatchAllocator redefinitionBatchAllocator,
                    AgentBuilder.RedefinitionStrategy.Listener redefinitionListener,
                    int batch)

Applies all types that this collector collected.

Parameters:

instrumentation - The instrumentation instance to apply changes to.

redefinitionBatchAllocator - The redefinition batch allocator to use.

redefinitionListener - The redefinition listener to use.

batch - The next batch's index.

Returns:

The next batch's index after this application.

doApply

protected abstract void doApply(Instrumentation instrumentation,
                                List<Class<?>> types)
                         throws UnmodifiableClassException,
                                ClassNotFoundException

Applies this collector.

Parameters:

instrumentation - The instrumentation instance to apply the transformation for.

types - The types of the current patch to transform.

Throws:

UnmodifiableClassException - If a class is not modifiable.

ClassNotFoundException - If a class could not be found.
