Class AsmVisitorWrapper.ForDeclaredMethods

java.lang.Object

net.bytebuddy.asm.AsmVisitorWrapper.ForDeclaredMethods

All Implemented Interfaces:

AsmVisitorWrapper

Enclosing interface:

AsmVisitorWrapper

public static class AsmVisitorWrapper.ForDeclaredMethods
extends Object
implements AsmVisitorWrapper

An ASM visitor wrapper that allows to wrap declared methods of the instrumented type with a AsmVisitorWrapper.ForDeclaredMethods.MethodVisitorWrapper.

Note: Inherited methods are not matched by this visitor, even if they are intercepted by a normal interception.

Constructor Detail

ForDeclaredMethods

public ForDeclaredMethods()

Creates a new visitor wrapper for declared methods.

ForDeclaredMethods

protected ForDeclaredMethods(List<AsmVisitorWrapper.ForDeclaredMethods.Entry> entries,
                             int writerFlags,
                             int readerFlags)

Creates a new visitor wrapper for declared methods.

Parameters:

entries - The list of entries that describe matched methods in their application order.

readerFlags - The reader flags to set.

writerFlags - The writer flags to set.

Method Detail

method

public AsmVisitorWrapper.ForDeclaredMethods method(ElementMatcher<? super MethodDescription> matcher,
                                                   AsmVisitorWrapper.ForDeclaredMethods.MethodVisitorWrapper... methodVisitorWrapper)

Defines a new method visitor wrapper to be applied if the given method matcher is matched. Previously defined entries are applied before the given matcher is applied.

Parameters:

matcher - The matcher to identify methods to be wrapped.

methodVisitorWrapper - The method visitor wrapper to be applied if the given matcher is matched.

Returns:

A new ASM visitor wrapper that applied the given method visitor wrapper if the supplied matcher is matched.

method

public AsmVisitorWrapper.ForDeclaredMethods method(ElementMatcher<? super MethodDescription> matcher,
                                                   List<? extends AsmVisitorWrapper.ForDeclaredMethods.MethodVisitorWrapper> methodVisitorWrappers)

Defines a new method visitor wrapper to be applied if the given method matcher is matched. Previously defined entries are applied before the given matcher is applied.

Parameters:

matcher - The matcher to identify methods to be wrapped.

methodVisitorWrappers - The method visitor wrapper to be applied if the given matcher is matched.

Returns:

A new ASM visitor wrapper that applied the given method visitor wrapper if the supplied matcher is matched.

writerFlags

public AsmVisitorWrapper.ForDeclaredMethods writerFlags(int flags)

Sets flags for the ClassWriter this wrapper is applied to.

Parameters:

flags - The flags to set for the ClassWriter.

Returns:

A new ASM visitor wrapper that sets the supplied writer flags.

readerFlags

public AsmVisitorWrapper.ForDeclaredMethods readerFlags(int flags)

Sets flags for the ClassReader this wrapper is applied to.

Parameters:

flags - The flags to set for the ClassReader.

Returns:

A new ASM visitor wrapper that sets the supplied reader flags.

mergeWriter

public int mergeWriter(int flags)

Description copied from interface: AsmVisitorWrapper

Defines the flags that are provided to any ClassWriter when writing a class. Typically, this gives opportunity to instruct ASM to compute stack map frames or the size of the local variables array and the operand stack. If no specific flags are required for applying this wrapper, the given value is to be returned.

Specified by:

mergeWriter in interface AsmVisitorWrapper

Parameters:

flags - The currently set flags. This value should be combined (e.g. flags | foo) into the value that is returned by this wrapper.

Returns:

The flags to be provided to the ASM ClassWriter.

mergeReader

public int mergeReader(int flags)

Description copied from interface: AsmVisitorWrapper

Defines the flags that are provided to any ClassReader when reading a class if applicable. Typically, this gives opportunity to instruct ASM to expand or skip frames and to skip code and debug information. If no specific flags are required for applying this wrapper, the given value is to be returned.

Specified by:

mergeReader in interface AsmVisitorWrapper

Parameters:

flags - The currently set flags. This value should be combined (e.g. flags | foo) into the value that is returned by this wrapper.

Returns:

The flags to be provided to the ASM ClassReader.

wrap

public ClassVisitor wrap(TypeDescription instrumentedType,
                         ClassVisitor classVisitor,
                         Implementation.Context implementationContext,
                         TypePool typePool,
                         FieldList<FieldDescription.InDefinedShape> fields,
                         MethodList<?> methods,
                         int writerFlags,
                         int readerFlags)

Description copied from interface: AsmVisitorWrapper

Applies a ClassVisitorWrapper to the creation of a DynamicType.

Specified by:

wrap in interface AsmVisitorWrapper

Parameters:

instrumentedType - The instrumented type.

classVisitor - A ClassVisitor to become the new primary class visitor to which the created DynamicType is written to.

implementationContext - The implementation context of the current instrumentation.

typePool - The type pool that was provided for the class creation.

fields - The instrumented type's fields.

methods - The instrumented type's methods non-ingored declared and virtually inherited methods.

writerFlags - The ASM ClassWriter flags to consider.

readerFlags - The ASM ClassReader flags to consider.

Returns:

A new ClassVisitor that usually delegates to the ClassVisitor delivered in the argument.
