  - ASN1BitString
```
public ASN1BitString(byte[] data,
                     int padBits)
```
    Base constructor.
    
    Parameters:
    
    data - the octets making up the bit string.
    
    padBits - the number of extra bits at the end of the string.
- Method Detail
  - getPadBits
```
protected static int getPadBits(int bitString)
```
    Parameters:
    
    bitString - an int containing the BIT STRING
    
    Returns:
    
    the correct number of pad bits for a bit string defined in a 32 bit constant
  - getBytes
```
protected static byte[] getBytes(int bitString)
```
    Parameters:
    
    bitString - an int containing the BIT STRING
    
    Returns:
    
    the correct number of bytes for a bit string defined in a 32 bit constant
  - getString
```
public java.lang.String getString()
```
    Return a String representation of this BIT STRING
    
    Specified by:
    
    getString in interface ASN1String
    
    Returns:
    
    a String representation.
  - intValue
```
public int intValue()
```
    Returns:
    
    the value of the bit string as an int (truncating if necessary)
  - getOctets
```
public byte[] getOctets()
```
    Return the octets contained in this BIT STRING, checking that this BIT STRING really does represent an octet aligned string. Only use this method when the standard you are following dictates that the BIT STRING will be octet aligned.
    
    Returns:
    
    a copy of the octet aligned data.
  - getBytes

public byte[] getBytes()
```
  - getPadBits
```
public int getPadBits()
```
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Specified by:
    
    hashCode in class ASN1Primitive
  - getLoadedObject
```
public ASN1Primitive getLoadedObject()
