  - setClass
```
public void setClass(CP name)
```
    Define this class to have this name.
    
    Parameters:
    
    name - CPE representing name for class. (This is usually a ClassCP)
  - setNoSuperClass
```
public void setNoSuperClass()
```
    Define this class to have no superclass. Should only ever be used for java.lang.Object
  - setSuperClass
```
public void setSuperClass(CP name)
```
    Define this class to have this superclass
    
    Parameters:
    
    name - CPE representing name for class. (This is usually a ClassCP)
  - setClassAccess
```
public void setClassAccess(short access)
```
    Set the class access for this class. Constants understood by this are present along with the java Beta distribution.
    
    Parameters:
    
    access - number representing access permissions for the entire class.
    
    See Also:
    
    RuntimeConstants
  - addInterface
```
public void addInterface(CP ifc)
```
    Add this CP to the list of interfaces supposedly implemented by this class. Note that the CP ought to be a ClassCP to make sense to the VM.
  - addInterface
```
public void addInterface(CP[] ilist)
```
    Add this to the list of interfaces supposedly implemented by this class. Note that each CP is usually a ClassCP.
    
    Parameters:
    
    ilist - An array of CP items representing the interfaces implemented by this class.
  - addField
```
public void addField(Var v)
```
  - write
```
public void write(DataOutputStream out)
           throws IOException,
                  jasError
```
    Write the contents of the class.
    
    Parameters:
    
    out - DataOutputStream on which the contents are written.
    
    Throws:
    
    IOException
    
    jasError
  - addCPItem
```
public void addCPItem(CP cp)
```
    This is the method to add CPE items to a class. CPE items for a class are "uniquefied". Ie, if you add a CPE items whose contents already exist in the class, only one entry is finally written out when the class is written.
    
    Parameters:
    
    cp - Item to be added to the class
  - addMethod
```
public void addMethod(short acc,
                      String name,
                      String sig,
                      CodeAttr code,
                      ExceptAttr ex)
```
    Here is where code gets added to a class.
    
    Parameters:
    
    acc - method_access permissions, expressed with some combination of the values defined in RuntimeConstants
    
    name - Name of the method
    
    sig - Signature for the method
    
    code - Actual code for the method
    
    ex - Any exception attribute to be associated with method
  - setClassSynth
```
public void setClassSynth(boolean b)
```
  - isClassSynth
```
public boolean isClassSynth()
```
  - setClassDepr
```
public void setClassDepr(DeprecatedAttr d)
```
  - setClassSigAttr
```
public void setClassSigAttr(SignatureAttr s)
```
  - setClassAnnotAttrVis
```
public void setClassAnnotAttrVis(VisibilityAnnotationAttr s)
```
  - setClassAnnotAttrInvis
```
public void setClassAnnotAttrInvis(VisibilityAnnotationAttr s)
```
  - finishInnerClassAttr
```
public void finishInnerClassAttr(InnerClassAttr attr)
```
  - addEnclMethAttr
```
public void addEnclMethAttr(EnclMethAttr attr)
```
  - setSource
```
public void setSource(SourceAttr source)
```
    Add an attribute specifying the name of the source file for the class
    
    Parameters:
    
    source - SourceAttribute specifying the source for the file
  - setSource
```
public void setSource(String source)
```
    Add an attribute specifying the name of the source file for the clas.
    
    Parameters:
    
    source - String with the name of the class
  - addGenericAttr
```
public void addGenericAttr(GenericAttr g)
```
    Add a generic attribute to the class file. A generic attribute contains a stream of uninterpreted bytes which is ignored by the VM (as long as its name doesn't conflict with other names for attributes that are understood by the VM)
  - addMethod
```
public void addMethod(Method m)
```
    This allows more control over generating CP's for methods if you feel so inclined.
  - addBootstrapMethod
```
public int addBootstrapMethod(MethodHandleCP bsm,
                              CP[] argCPs)
```
