Applies the given transformer for the already supplied matcher.

Specified by:

transform in interface AgentBuilder.Identified

Parameters:

transformer - The transformer to apply.

Returns:

This agent builder with the transformer being applied when the previously supplied matcher identified a type for instrumentation which also allows for the registration of subsequent transformers.

type

public AgentBuilder.Identified type(AgentBuilder.RawMatcher matcher)

Description copied from interface: AgentBuilder

Matches a type being loaded in order to apply the supplied AgentBuilder.Transformers before loading this type.

Specified by:

type in interface AgentBuilder

Parameters:

matcher - A matcher that decides if the entailed AgentBuilder.Transformers should be applied for a type that is being loaded.

Returns:

A definable that represents this agent builder which allows for the definition of one or several AgentBuilder.Transformers to be applied when the given matcher indicates a match.

type

public AgentBuilder.Identified type(ElementMatcher<? super TypeDescription> typeMatcher)

Description copied from interface: AgentBuilder

Matches a type being loaded in order to apply the supplied AgentBuilder.Transformers before loading this type.

Specified by:

type in interface AgentBuilder

Parameters:

typeMatcher - An ElementMatcher that is applied on the type being loaded that decides if the entailed AgentBuilder.Transformers should be applied for that type.

Returns:

A definable that represents this agent builder which allows for the definition of one or several AgentBuilder.Transformers to be applied when the given typeMatcher indicates a match.

type

public AgentBuilder.Identified type(ElementMatcher<? super TypeDescription> typeMatcher,
                                    ElementMatcher<? super ClassLoader> classLoaderMatcher)

Description copied from interface: AgentBuilder

Matches a type being loaded in order to apply the supplied AgentBuilder.Transformers before loading this type.

Specified by:

type in interface AgentBuilder

Parameters:

typeMatcher - An ElementMatcher that is applied on the type being loaded that decides if the entailed AgentBuilder.Transformers should be applied for that type.

classLoaderMatcher - An ElementMatcher that is applied to the ClassLoader that is loading the type being loaded. This matcher is always applied first where the type matcher is not applied in case that this matcher does not indicate a match.

Returns:

A definable that represents this agent builder which allows for the definition of one or several AgentBuilder.Transformers to be applied when both the given typeMatcher and classLoaderMatcher indicate a match.

withByteBuddy

public AgentBuilder withByteBuddy(ByteBuddy byteBuddy)

Description copied from interface: AgentBuilder

Defines the given ByteBuddy instance to be used by the created agent.

Specified by:

withByteBuddy in interface AgentBuilder

Parameters:

byteBuddy - The Byte Buddy instance to be used.

Returns:

A new instance of this agent builder which makes use of the given byteBuddy instance.

withListener

public AgentBuilder withListener(AgentBuilder.Listener listener)

Description copied from interface: AgentBuilder

Defines the given AgentBuilder.Listener to be notified by the created agent. The given listener is notified after any other listener that is already registered. If a listener is registered twice, it is also notified twice.

Specified by:

withListener in interface AgentBuilder

Parameters:

listener - The listener to be notified.

Returns:

A new instance of this agent builder which creates an agent that informs the given listener about events.

withTypeStrategy

public AgentBuilder withTypeStrategy(AgentBuilder.TypeStrategy typeStrategy)

Description copied from interface: AgentBuilder

Defines the use of the given definition handler that determines if a type should be rebased or redefined.

Specified by:

withTypeStrategy in interface AgentBuilder

Parameters:

typeStrategy - The definition handler to use.

Returns:

A new instance of this agent builder which uses the given definition handler.

withBinaryLocator

public AgentBuilder withBinaryLocator(AgentBuilder.BinaryLocator binaryLocator)

Description copied from interface: AgentBuilder

Defines the use of the given binary locator for locating binary data to given class names.

Specified by:

withBinaryLocator in interface AgentBuilder

Parameters:

binaryLocator - The binary locator to use.

Returns:

A new instance of this agent builder which uses the given binary locator for looking up class files.

withNativeMethodPrefix

public AgentBuilder withNativeMethodPrefix(String prefix)

Description copied from interface: AgentBuilder

Enables the use of the given native method prefix for instrumented methods. Note that this prefix is also applied when preserving non-native methods. The use of this prefix is also registered when installing the final agent with an Instrumentation.

Specified by:

withNativeMethodPrefix in interface AgentBuilder

Parameters:

prefix - The prefix to be used.

Returns:

A new instance of this agent builder which uses the given native method prefix.

withoutNativeMethodPrefix

public AgentBuilder withoutNativeMethodPrefix()

Description copied from interface: AgentBuilder

Disables the use of a native method prefix for instrumented methods.

Specified by:

withoutNativeMethodPrefix in interface AgentBuilder

Returns:

A new instance of this agent builder which does not use a native method prefix.

withAccessControlContext

public AgentBuilder withAccessControlContext(AccessControlContext accessControlContext)

Description copied from interface: AgentBuilder

Defines classes to be loaded using the given access control context.

Specified by:

withAccessControlContext in interface AgentBuilder

Parameters:

accessControlContext - The access control context to be used for loading classes.

Returns:

A new instance of this agent builder which uses the given access control context for class loading.

withInitializationStrategy

public AgentBuilder withInitializationStrategy(AgentBuilder.InitializationStrategy initializationStrategy)

Description copied from interface: AgentBuilder

Defines a given initialization strategy to be applied to generated types. An initialization strategy is responsible for setting up a type after it was loaded. This initialization must be performed after the transformation because a Java agent is only invoked before loading a type. By default, the initialization logic is added to a class's type initializer which queries a global object for any objects that are to be injected into the generated type.

Specified by:

withInitializationStrategy in interface AgentBuilder

Parameters:

initializationStrategy - The initialization strategy to use.

Returns:

A new instance of this agent builder that applies the given initialization strategy.

Specified by:

withRedefinitionStrategy in interface AgentBuilder

Parameters:

redefinitionStrategy - The redefinition strategy to apply.

Returns:

A new instance of this agent builder that applies the given redefinition strategy.
