Enum Constant Detail

INSTANCE

public static final AgentBuilder.InstallationListener.NoOp INSTANCE

The singleton instance.

Method Detail

values

public static AgentBuilder.InstallationListener.NoOp[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AgentBuilder.InstallationListener.NoOp c : AgentBuilder.InstallationListener.NoOp.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AgentBuilder.InstallationListener.NoOp valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

onBeforeInstall

public void onBeforeInstall(Instrumentation instrumentation,
                            ResettableClassFileTransformer classFileTransformer)

Invoked prior to the installation of a class file transformer.

Specified by:

onBeforeInstall in interface AgentBuilder.InstallationListener

Parameters:

instrumentation - The instrumentation on which the class file transformer is installed.

classFileTransformer - The class file transformer that is being installed.

onInstall

public void onInstall(Instrumentation instrumentation,
                      ResettableClassFileTransformer classFileTransformer)

Invoked upon the successful installation of a class file transformer. This method is only invoked if no error occurred during the installation or if such an error was handled by AgentBuilder.InstallationListener.onError(Instrumentation, ResettableClassFileTransformer, Throwable).

Specified by:

onInstall in interface AgentBuilder.InstallationListener

Parameters:

instrumentation - The instrumentation on which the class file transformer is installed.

classFileTransformer - The class file transformer that is being installed.

onError

public Throwable onError(Instrumentation instrumentation,
                         ResettableClassFileTransformer classFileTransformer,
                         Throwable throwable)

Invoked if an installation causes an error. The listener has an opportunity to handle the error. This method is invoked prior to AgentBuilder.InstallationListener.onInstall(Instrumentation, ResettableClassFileTransformer).

Specified by:

onError in interface AgentBuilder.InstallationListener

Parameters:

instrumentation - The instrumentation on which the class file transformer is installed.

classFileTransformer - The class file transformer that is being installed.

throwable - The throwable that causes the error.

Returns:

The error to propagate or null if the error is handled. Any subsequent listeners are not called if the exception is handled.

onReset

public void onReset(Instrumentation instrumentation,
                    ResettableClassFileTransformer classFileTransformer)

Invoked if an installation is reset.

Specified by:

onReset in interface AgentBuilder.InstallationListener

Parameters:

instrumentation - The instrumentation on which the class file transformer is installed.

classFileTransformer - The class file transformer that is being installed.
