Enum Constant Detail

INSTANCE

public static final AsmVisitorWrapper.NoOp INSTANCE

The singleton instance.

Method Detail

values

public static AsmVisitorWrapper.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 (AsmVisitorWrapper.NoOp c : AsmVisitorWrapper.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 AsmVisitorWrapper.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

mergeWriter

public int mergeWriter(int flags)

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)

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)

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-ignored 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.
