Record Class DefaultClassTransformerRegistry.RegisteredClassTransformer

java.lang.Object

java.lang.Record

eu.cloudnetservice.wrapper.transform.DefaultClassTransformerRegistry.RegisteredClassTransformer

Record Components:

transformer - the transformer to obtain the class file transform instance from for accepted classes.

instrumentation - the instrumentation to which this transformer is registered.

All Implemented Interfaces:

ClassFileTransformer

Enclosing class:

DefaultClassTransformerRegistry

private static record DefaultClassTransformerRegistry.RegisteredClassTransformer(@NonNull ClassTransformer transformer, @NonNull Instrumentation instrumentation)
extends Record
implements ClassFileTransformer

An implementation of a class file transformer that parses and transforms class files using the given CloudNet transformer. The transform call is ignored if the given transformer is rejecting the class, and this transformer will be unregistered from the given instrumentation if the acceptance check returns ClassTransformer.TransformWillingness.ACCEPT_ONCE.

Since:

4.0

The field for the transformer record component.

instrumentation

@NonNull
private final @NonNull Instrumentation instrumentation

The field for the instrumentation record component.

Constructor Details

RegisteredClassTransformer

private RegisteredClassTransformer(@NonNull
 @NonNull ClassTransformer transformer,
 @NonNull
 @NonNull Instrumentation instrumentation)

Creates an instance of a RegisteredClassTransformer record class.

Parameters:

transformer - the value for the transformer record component

instrumentation - the value for the instrumentation record component

Method Details

transform

public byte[] transform(@Nullable
 @Nullable ClassLoader loader,
 @NonNull
 @NonNull String className,
 @Nullable
 @Nullable Class<?> classBeingRedefined,
 @Nullable
 @Nullable ProtectionDomain protectionDomain,
 byte[] classfileBuffer)

Specified by:

transform in interface ClassFileTransformer

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

transformer

@NonNull
public @NonNull ClassTransformer transformer()

Returns the value of the transformer record component.

Returns:

the value of the transformer record component

instrumentation

@NonNull
public @NonNull Instrumentation instrumentation()

Returns the value of the instrumentation record component.

Returns:

the value of the instrumentation record component
