Class FieldGen
- Cloneable, NamedAndTyped, java.io.Serializable
Template class for building up a field. The only extraordinary thing
one can do is to add a constant value attribute to a field (which must of
course be compatible with to the declared type).

FieldGen
public FieldGen(int access_flags,
Type type,
String name,
ConstantPoolGen cp)
Declare a field. If it is static (isStatic() == true) and has a
basic type like int or String it may have an initial value
associated with it as defined by setInitValue().
access_flags
- access qualifierstype
- field typename
- field namecp

FieldGen
public FieldGen(Field field,
ConstantPoolGen cp)
Instantiate from existing field.
field
- Field objectcp
- constant pool (must contain the same entries as the field's constant pool)
addObserver
public void addObserver(FieldObserver o)
Add observer for this object.
cancelInitValue
public void cancelInitValue()
Remove any initial value.
getField
public Field getField()
Get field object after having set up all necessary values.
getInitValue
public String getInitValue()
removeObserver
public void removeObserver(FieldObserver o)
Remove observer for this object.
setInitValue
public void setInitValue(String str)
Set (optional) initial value of field, otherwise it will be set to null/0/false
by the JVM automatically.
setInitValue
public void setInitValue(boolean b)
setInitValue
public void setInitValue(byte b)
setInitValue
public void setInitValue(char c)

public void setInitValue(double d)

public void setInitValue(float f)
setInitValue
public void setInitValue(int i)

public void setInitValue(long l)
setInitValue
public void setInitValue(short s)
toString
public final String toString()
Return string representation close to declaration format,
`public static final short MAX = 100', e.g..
- String representation of field
update
public void update()
Call notify() method on all observers. This method is not called
automatically whenever the state has changed, but has to be
called by the user after he has finished editing the object.
