```
public int compareTo(Object o)
```
    Specified by:
    
    compareTo in interface Comparable
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - getConstant
```
public Constant getConstant()
```

    Specified by:
    
    getConstant in interface IBinaryField
    
    Returns:
    org.eclipse.jdt.internal.compiler.impl.Constant
  - getGenericSignature
```
public char[] getGenericSignature()
```
    Description copied from interface: IBinaryField
    
    Answer the receiver's signature which describes the parameter & return types as specified in section 4.4.4 of the Java 2 VM spec.
    
    Specified by:
    
    getGenericSignature in interface IBinaryField
  - getModifiers
```
public int getModifiers()
```
    Answer an int whose bits are set according the access constants defined by the VM spec. Set the AccDeprecated and AccSynthetic bits if necessary
    
    Specified by:
    
    getModifiers in interface IGenericField
    
    Returns:
    int
  - getName
```
public char[] getName()
```
    Answer the name of the field.
    
    Specified by:
    
    getName in interface IBinaryField
    
    Returns:
    char[]
  - getTagBits
```
public long getTagBits()
```
    Description copied from interface: IBinaryField
    
    Answer the tagbits set according to the bits for annotations.
    
    Specified by:
    
    getTagBits in interface IBinaryField
  - getTypeName
```
public char[] getTypeName()
```
    Answer the resolved name of the receiver's type in the class file format as specified in section 4.3.2 of the Java 2 VM spec. For example: - java.lang.String is Ljava/lang/String; - an int is I - a 2 dimensional array of strings is [[Ljava/lang/String; - an array of floats is [F
    
    Specified by:
    
    getTypeName in interface IBinaryField
    
    Returns:
    char[]
  - getAnnotations
```
public IBinaryAnnotation[] getAnnotations()
```
    Description copied from interface: IBinaryField
    
    Answer the runtime visible and invisible annotations for this field or null if none.
    
    Specified by:
    
    getAnnotations in interface IBinaryField
    
    Returns:
    the annotations or null if there is none.
  - getWrappedConstantValue
```
public Object getWrappedConstantValue()
```
    Return a wrapper that contains the constant of the field.
    
    Returns:
    java.lang.Object
  - hasConstant
```
public boolean hasConstant()
```
    Return true if the field has a constant value attribute, false otherwise.
    
    Returns:
    boolean
  - initialize
```
protected void initialize()
```
    This method is used to fully initialize the contents of the receiver. All methodinfos, fields infos will be therefore fully initialized and we can get rid of the bytes.
  - isSynthetic
```
public boolean isSynthetic()
```
    Return true if the field is a synthetic field, false otherwise.
    
    Returns:
    boolean
  - sizeInBytes
```
public int sizeInBytes()
```
    Answer the size of the receiver in bytes.
    
    Returns:
    int
  - throwFormatException
```
public void throwFormatException()
                          throws ClassFormatException
```
    Throws:
    
    ClassFormatException
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - toStringContent
```
