Method Details

visit

public void visit(int version,
 int access,
 @NonNull
 String name,
 @NonNull
 ClassInfo additionalInfo)

Visits the header of the class.

Parameters:

version - the class version

access - the class's access flags (see Access)

name - the internal name of the class

additionalInfo - additional class information

visitInnerClass

public void visitInnerClass(@NonNull
 String name,
 @Nullable
 String outerName,
 @Nullable
 String innerName,
 int access)

Visits information about an inner class, which is not necessarily a member of the class being visited.

Parameters:

name - the internal name of an inner class

outerName - the internal name of the class to which the inner class belongs; null for not member classes

innerName - the (simple) name of the inner class inside its enclosing class; null for anonymous inner classes

access - the access flags of the inner class as originally declared in the enclosing class

visitField

@Nullable
public FieldVisitor visitField(int access,
 @NonNull
 String name,
 @NonNull
 String desc,
 @Nullable
 String signature,
 @Nullable
 Object value)

Visits a field of the class.

Parameters:

access - the field's access flags (see Access)

name - the field's name

desc - the field's descriptor (see JavaType)

signature - the field's signature; null when the field's type does not use generic types

value - the field's initial value; null when the field does not have an initial value; otherwise, must be an Integer, a Float, a Long, a Double or a String (for int, float, long or String fields respectively); this parameter is only used for static fields; its value is ignored for non static fields, which must be initialized through bytecode instructions in constructors or methods

Returns:

a visitor to visit field annotations and attributes, or null if this class visitor is not interested in visiting these annotations and attributes

visitMethod

@Nullable
public MethodVisitor visitMethod(int access,
 @NonNull
 String name,
 @NonNull
 String desc,
 @Nullable
 String signature,
 @Nullable
 String[] exceptions)

Visits a method of the class. This method must return a new MethodVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Parameters:

access - the method's access flags (see Opcodes)

name - the method's name

desc - the method's descriptor (see JavaType)

signature - the method's signature, null if the method parameters, return type and exceptions do not use generic types

exceptions - the internal names of the method's exception classes

Returns:

an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method

toByteArray

public byte[] toByteArray()

Returns the bytecode of the class that was built with this class visitor.
