Constructor Detail

AsyncClassesInstrumentationAgent

protected AsyncClassesInstrumentationAgent(java.lang.String arguments,
                                           java.lang.instrument.Instrumentation instrumentation)

Method Detail

premain

public static void premain(java.lang.String args,
                           java.lang.instrument.Instrumentation instrumentation)
                    throws java.lang.Exception

JVM hook to statically load the javaagent at startup. After the Java Virtual Machine (JVM) has initialized, the premain method will be called. Then the real application main method will be called.

Parameters:

args - arguments supplied to the agent

instrumentation - Instrumentation object passed by JVM

Throws:

java.lang.Exception - thrown when agent is unable to start

agentmain

public static void agentmain(java.lang.String args,
                             java.lang.instrument.Instrumentation instrumentation)
                      throws java.lang.Exception

JVM hook to dynamically load javaagent at runtime. The agent class may have an agentmain method for use when the agent is started after VM startup.

Parameters:

args - arguments supplied to the agent

instrumentation - Instrumentation object passed by JVM

Throws:

java.lang.Exception - thrown when agent is unable to start

createTransformers

protected java.util.Collection<java.lang.instrument.ClassFileTransformer> createTransformers(boolean canRetransform)

Overrides:

createTransformers in class net.tascalate.instrument.agent.AbstractInstrumentationAgent

readLambdaClassName

protected java.lang.String readLambdaClassName(byte[] bytes)

Overrides:

readLambdaClassName in class net.tascalate.instrument.agent.AbstractLambdaAwareInstrumentationAgent
