- - org.springframework.asm.ClassWriter

Direct Known Subclasses:

SpelCompiler.ExpressionClassWriter
```
public class ClassWriter
extends ClassVisitor
```
A ClassVisitor that generates classes in bytecode form. More precisely this visitor generates a byte array conforming to the Java class file format. It can be used alone, to generate a Java class "from scratch", or with one or more ClassReader and adapter class visitor to generate a modified class from one or more existing Java classes.

- Field Detail
  - COMPUTE_MAXS
```
public static final int COMPUTE_MAXS
```
    Flag to automatically compute the maximum stack size and the maximum number of local variables of methods. If this flag is set, then the arguments of the visitMaxs method of the MethodVisitor returned by the visitMethod method will be ignored, and computed automatically from the signature and the bytecode of each method.

    ClassWriter(int), Constant Field Values
  - COMPUTE_FRAMES
```
public static final int COMPUTE_FRAMES
```
    Flag to automatically compute the stack map frames of methods from scratch. If this flag is set, then the calls to the MethodVisitor.visitFrame(int, int, java.lang.Object[], int, java.lang.Object[]) method are ignored, and the stack map frames are recomputed from the methods bytecode. The arguments of the visitMaxs method are also ignored and recomputed from the bytecode. In other words, COMPUTE_FRAMES implies COMPUTE_MAXS.

- Constructor Detail
  - ClassWriter
```
public ClassWriter(int flags)
```
    Constructs a new ClassWriter object.
    
    Parameters:
    
    flags - option flags that can be used to modify the default behavior of this class. See COMPUTE_MAXS, COMPUTE_FRAMES.
  - ClassWriter
```
public ClassWriter(ClassReader classReader,
                   int flags)
```
    Constructs a new ClassWriter object and enables optimizations for "mostly add" bytecode transformations. These optimizations are the following:
    - The constant pool from the original class is copied as is in the new class, which saves time. New constant pool entries will be added at the end if necessary, but unused constant pool entries won't be removed.
    - Methods that are not transformed are copied as is in the new class, directly from the original class bytecode (i.e. without emitting visit events for all the method instructions), which saves a lot of time. Untransformed methods are detected by the fact that the ClassReader receives MethodVisitor objects that come from a ClassWriter (and not from any other ClassVisitor instance).
    Parameters:
    
    classReader - the 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.
    
    flags - option flags that can be used to modify the default behavior of this class. These option flags do not affect methods that are copied as is in the new class. This means that neither the maximum stack size nor the stack frames will be computed for these methods. See COMPUTE_MAXS, COMPUTE_FRAMES.

  - getMergedType
```
int getMergedType(int type1,
                  int type2)
```
    Returns the index of the common super type of the two given types. This method calls getCommonSuperClass(java.lang.String, java.lang.String) and caches the result in the items hash table to speedup future calls with the same parameters.
    
    Parameters:
    
    type1 - index of an internal name in typeTable.
    
    type2 - index of an internal name in typeTable.
    
    Returns:
    
    the index of the common super type of the two given types.
  - getCommonSuperClass
```
protected java.lang.String getCommonSuperClass(java.lang.String type1,
                                               java.lang.String type2)
```
    Returns the common super type of the two given types. The default implementation of this method loads the two given classes and uses the java.lang.Class methods to find the common super class. It can be overridden to compute this common super type in other ways, in particular without actually loading any class, or to take into account the class that is currently being generated by this ClassWriter, which can of course not be loaded since it is under construction.
    
    Parameters:
    
    type1 - the internal name of a class.
    
    type2 - the internal name of another class.
    
    Returns:
    
    the internal name of the common super class of the two given classes.
  - getClassLoader
```
protected java.lang.ClassLoader getClassLoader()
```
  - get
```
private Item get(Item key)
```
    Returns the constant pool's hash table item which is equal to the given item.
    
    Parameters:
    
    key - a constant pool item.
    
    Returns:
    
    the constant pool's hash table item which is equal to the given item, or null if there is no such item.
  - put
```
private void put(Item i)
```
    Puts the given item in the constant pool's hash table. The hash table must not already contains this item.
    
    Parameters:
    
    i - the item to be added to the constant pool's hash table.
  - put122
```
private void put122(int b,
                    int s1,
                    int s2)
```
    Puts one byte and two shorts into the constant pool.
    
    Parameters:
    
    b - a byte.
    
    s1 - a short.
    
    s2 - another short.
  - put112
```
private void put112(int b1,
                    int b2,
                    int s)
```
    Puts two bytes and one short into the constant pool.
    
    Parameters:
    
    b1 - a byte.
