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(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
mergeWriter
public int mergeWriter(int flags)
Defines the flags that are provided to anyClassWriter
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 interfaceAsmVisitorWrapper
- 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 anyClassReader
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 interfaceAsmVisitorWrapper
- 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 org.objectweb.asm.ClassVisitor wrap(TypeDescription instrumentedType, org.objectweb.asm.ClassVisitor classVisitor, Implementation.Context implementationContext, TypePool typePool, FieldList<FieldDescription.InDefinedShape> fields, MethodList<?> methods, int writerFlags, int readerFlags)
Applies aClassVisitorWrapper
to the creation of aDynamicType
.- Specified by:
wrap
in interfaceAsmVisitorWrapper
- Parameters:
instrumentedType
- The instrumented type.classVisitor
- AClassVisitor
to become the new primary class visitor to which the createdDynamicType
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 ASMClassWriter
flags to consider.readerFlags
- The ASMClassReader
flags to consider.- Returns:
- A new
ClassVisitor
that usually delegates to theClassVisitor
delivered in the argument.
