public class BIT_STRING
extends ASN1Object
This class implements the native ASN.1 type "BIT STRING".

Variable Index

o bits_not_valid
Number of bits not valid in the byte array of bits.
o value
The bits of the BitString in a byte array.

Constructor Index

o BIT_STRING()
Creates a new BitString.
o BIT_STRING(byte[])
Create a new BitString where all bits of the byte array are valid.
o BIT_STRING(byte[], int)
Creates a new BitString from an array and an integer.

Method Index

o bitsNotValid()
Returns the number of bits which are not valid.
o decode(int, int, DerDecodeInputStream)
Decodes the next available data from the DerDecodeInputStream.
o encode(DerEncodeOutputStream)
DER encodes this ASN1Object and write the result to the DerEncodeOutputStream.
o getValue()
Returns the value of this BIT_STRING as a byte array.
o init()
Initialize the object factory method.
o setValue(Object)
Sets the value of this object to value.
o toString()
Returns a string that represents the contents of this BitString.

Variables

o bits_not_valid 
 protected int bits_not_valid
Number of bits not valid in the byte array of bits.

o value 
 protected byte value[]
The bits of the BitString in a byte array.

Constructors

o BIT_STRING 
 protected BIT_STRING()
Creates a new BitString. Called by the OBJECTFactory.

o BIT_STRING 
 public BIT_STRING(byte array[],
                   int bitsNotValid)
Creates a new BitString from an array and an integer.

Parameters:
array - the bits in a byte array
bitsNotValid - number of bits which are not valid in the last byte
o BIT_STRING 
 public BIT_STRING(byte array[])
Create a new BitString where all bits of the byte array are valid.

Parameters:
bits - the bits in a byte array

Methods

o init 
 protected static void init()
Initialize the object factory method.

o getValue 
 public Object getValue()
Returns the value of this BIT_STRING as a byte array.

Returns:
the bits of this BIT_STRING in a byte array
Overrides:
getValue in class ASN1Object
o setValue 
 public void setValue(Object object)
Sets the value of this object to value.

Overrides:
setValue in class ASN1Object
o bitsNotValid 
 public int bitsNotValid()
Returns the number of bits which are not valid.

Returns:
the number of bits which are not valid
o encode 
 protected void encode(DerEncodeOutputStream os)
DER encodes this ASN1Object and write the result to the DerEncodeOutputStream.

Parameters:
os - the output stream to which to write the data
Overrides:
encode in class ASN1Object
o decode 
 protected void decode(int tag,
                       int length,
                       DerDecodeInputStream is) throws IOException
Decodes the next available data from the DerDecodeInputStream.

Parameters:
tag - the full tag of the current ASN1Object
length - the length of the ASN1Object which shall be decoded
Throws: IOException
if there is a problem with the DerDecodeInputStream
Overrides:
decode in class ASN1Object
o toString 
 public String toString()
Returns a string that represents the contents of this BitString.

Returns:
the string representation
Overrides:
toString in class ASN1Object
