Constructor Detail

Simple

protected Simple(AgentBuilder.RawMatcher rawMatcher,
                 AgentBuilder.Transformer transformer,
                 boolean decorator)

Creates a new transformation.

Parameters:

rawMatcher - The raw matcher that is represented by this transformation.

transformer - The transformer that is represented by this transformation.

decorator - true if this transformer serves as a decorator.

Method Detail

matches

public boolean matches(TypeDescription typeDescription,
                       ClassLoader classLoader,
                       JavaModule module,
                       Class<?> classBeingRedefined,
                       ProtectionDomain protectionDomain)

Decides if the given typeDescription should be instrumented with the entailed AgentBuilder.Transformers.

Specified by:

matches in interface AgentBuilder.RawMatcher

Parameters:

typeDescription - A description of the type to be instrumented.

classLoader - The class loader of the instrumented type. Might be null if this class loader represents the bootstrap class loader.

module - The transformed type's module or null if the current VM does not support modules.

classBeingRedefined - The class being redefined which is only not null if a retransformation is applied.

protectionDomain - The protection domain of the type being transformed.

Returns:

true if the entailed AgentBuilder.Transformers should be applied for the given typeDescription.

resolve

public AgentBuilder.Default.Transformation.Resolution resolve(TypeDescription typeDescription,
                                                              ClassLoader classLoader,
                                                              JavaModule module,
                                                              Class<?> classBeingRedefined,
                                                              boolean loaded,
                                                              ProtectionDomain protectionDomain,
                                                              TypePool typePool)

Resolves an attempted transformation to a specific transformation.

Specified by:

resolve in interface AgentBuilder.Default.Transformation

Parameters:

typeDescription - A description of the type that is to be transformed.

classLoader - The class loader of the type being transformed.

module - The transformed type's module or null if the current VM does not support modules.

classBeingRedefined - In case of a type redefinition, the loaded type being transformed or null if that is not the case.

loaded - true if the instrumented type is loaded.

protectionDomain - The protection domain of the type being transformed.

typePool - The type pool to apply during type creation.

Returns:

A resolution for the given type.
