public class ClassWriter extends Object implements ClassVisitor
Constructor Summary | |
---|---|
ClassWriter(boolean computeMaxs)
Constructs a new {@link ClassWriter ClassWriter} object.
| |
ClassWriter(boolean computeMaxs, boolean skipUnknownAttributes)
Constructs a new {@link ClassWriter} object.
| |
ClassWriter(ClassReader classReader, boolean computeMaxs)
Constructs a new {@link ClassWriter} object and enables optimizations for
"mostly add" bytecode transformations. |
Method Summary | |
---|---|
int | newClass(String value)
Adds a class reference to the constant pool of the class being build.
|
int | newConst(Object cst)
Adds a number or string constant to the constant pool of the class being
build. |
int | newField(String owner, String name, String desc)
Adds a field reference to the constant pool of the class being build.
|
int | newMethod(String owner, String name, String desc, boolean itf)
Adds a method reference to the constant pool of the class being build.
|
int | newNameType(String name, String desc)
Adds a name and type to the constant pool of the class being build. |
int | newUTF8(String value)
Adds an UTF8 string to the constant pool of the class being build. |
byte[] | toByteArray()
Returns the bytecode of the class that was build with this class writer.

AnnotationVisitor | visitAnnotation(String desc, boolean visible) |
void | visitAttribute(Attribute attr) |
void | visitEnd() |
FieldVisitor | visitField(int access, String name, String desc, String signature, Object value) |

Parameters: computeMaxs true if the maximum stack size and the maximum number of local variables must be automatically computed. If this flag is true, then the arguments of the {@link MethodVisitor#visitMaxs visitMaxs} method of the {@link MethodVisitor} returned by the {@link #visitMethod visitMethod} method will be ignored, and computed automatically from the signature and the bytecode of each method.
Parameters: computeMaxs true if the maximum stack size and the maximum number of local variables must be automatically computed. If this flag is true, then the arguments of the {@link MethodVisitor#visitMaxs visitMaxs} method of the {@link MethodVisitor} returned by the {@link #visitMethod visitMethod} method will be ignored, and computed automatically from the signature and the bytecode of each method. skipUnknownAttributes Deprecated. The value of this parameter is ignored.
Parameters: classReader the {@link ClassReader} used to read the original class. It will be used to copy the entire constant pool from the original class and also to copy other fragments of original bytecode where applicable. computeMaxs true if the maximum stack size and the maximum number of local variables must be automatically computed. If this flag is true, then the arguments of the {@link MethodVisitor#visitMaxs visitMaxs} method of the {@link MethodVisitor} returned by the {@link #visitMethod visitMethod} method will be ignored, and computed automatically from the signature and the bytecode of each method.
Parameters: value the internal name of the class.
Returns: the index of a new or already existing class reference item.
Parameters: cst the value of the constant to be added to the constant pool. This parameter must be an {@link Integer}, a {@link Float}, a {@link Long}, a {@link Double} or a {@link String}.
Returns: the index of a new or already existing constant item with the given value.
Parameters: owner the internal name of the field's owner class. name the field's name. desc the field's descriptor.
Returns: the index of a new or already existing field reference item.
Parameters: owner the internal name of the method's owner class. name the method's name. desc the method's descriptor. itf true if owner is an interface.
Returns: the index of a new or already existing method reference item.
Parameters: name a name. desc a type descriptor.
Returns: the index of a new or already existing name and type item.
Parameters: value the String value.
Returns: the index of a new or already existing UTF8 item.
Returns: the bytecode of the class that was build with this class writer.
