java.lang.Object

java.lang.Enum<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>

net.bytebuddy.agent.builder.AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe

All Implemented Interfaces:

Serializable, Comparable<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>, AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

Enclosing interface:

AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

public static enum AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe
extends Enum<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>
implements AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

A loader that is using unsafe API to load a lambda implementation. The code for loading the class looks similar to the following:

 Unsafe unsafe = Unsafe.getUnsafe();
  Class<?> lambdaClass = unsafe.defineAnonymousClass(caller.lookupClass(),
   binaryRepresentation,
   null);
 unsafe.ensureClassInitialized(lambdaClass);

Method Detail

values

public static AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe[] 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.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe c : AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe.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.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe 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

getType

protected String getType()

Returns the internal name of the unsafe type.

Returns:

The internal name of the unsafe type.

apply

public void apply(MethodVisitor methodVisitor)

Applies this loader.

Specified by:

apply in interface AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

Parameters:

methodVisitor - The method visitor to use.

getStackSize

public int getStackSize()

Returns the stack size that is required to implement this loader.

Specified by:

getStackSize in interface AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

Returns:

The stack size that is required to implement this loader.

getLocalVariableLength

public int getLocalVariableLength()

Returns the local variable length that is required to implement this loader.

Specified by:

getLocalVariableLength in interface AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

Returns:

The local variable length that is required to implement this loader.
