public class SnmpBitstring

extends SnmpVar

Class of SNMP Bitstring Variable - Sub-class of SnmpVar. This class can be used to create an SnmpVar object of type SnmpString. It also has methods to retrive the value in different forms(eg. String, byte).

Field Detail

s_emptyString

static final byte[] s_emptyString

immutable, hence shareable

byteValue

byte[] byteValue

byteValue is the master value of the OCTETSTRING and is always valid The value of the octet string, never null

value

java.lang.String value

The String representation of the bit string. value is the String representation that is generated only on demand then cached.

Constructor Detail

SnmpBitstring

SnmpBitstring()

SnmpBitstring

public SnmpBitstring(java.lang.String val)

Constructs a new SnmpBitstring taking a string instance as its argument. The bytes of the String should be encoded as required by the byte[] constructor.

Parameters:

val - The string value for creating a new SnmpBitstring object.

SnmpBitstring

public SnmpBitstring(byte[] b)

Constructs a new SnmpBitstring by taking an octet string. The first byte should contain the count of bits in the last byte, which are not relevant.

SnmpBitstring

public SnmpBitstring(byte[] b,
                     int size)
              throws SnmpException

This takes a byte array and encodes. This is different from the other constructors in that, there is no need to specify the count of unused bits in the last byte. The size parameter should just specify the total length of the bit string(which is the number of bits).

Parameters:

b - the byte array to be used.

size - the length of the bit string

Throws:

SnmpException - is thrown on invalid parameters such as size less than the total number of bits in the array.

Method Detail

newInstance

static SnmpVar newInstance(byte[] b)

Factory method for decode

getVarObject

public java.lang.Object getVarObject()

Returns the value of this SnmpBitstring SNMP variable as a String Object. This method is the same as toValue().

Overrides:

getVarObject in class SnmpVar

Returns:

the value of this SnmpBitstring object as a printable string.

toValue

public java.lang.Object toValue()

Returns the value of this SnmpBitstring SNMP variable as a string object. This method is the same as toString().

Overrides:

toValue in class SnmpVar

Returns:

the value of this SnmpBitstring object as a printable string.

toString

public java.lang.String toString()

To convert the value of this SnmpBitstring object to a printable string used in printing variables.

Overrides:

toString in class SnmpVar

Returns:

the value of SnmpBitstring object as a printable string.

toTagString

public java.lang.String toTagString()

To convert the value of this SnmpBitstring object to a printable string where the type is tagged before the value with a tag BITSTRING:.

Overrides:

toTagString in class SnmpVar

Returns:

the value of SnmpBitstring object as a printable where the type is tagged before the value with a Tag - BITSTRING: .

toBytes

public byte[] toBytes()

To return the value of this SnmpBitstring object as raw bytes.

Overrides:

toBytes in class SnmpVar

Returns:

The value of this SnmpBitstring as byte value.

getNumericValueAsString

public java.lang.String getNumericValueAsString()

This method will throw UnsupportedOperationException since this is not a numeric data type.

Overrides:

getNumericValueAsString in class SnmpVar

Returns:

Nothing is returned since this method throws an exception.

Throws:

java.lang.UnsupportedOperationException - Since this is not a numeric data type.

encode

int encode(byte[] buff,
           int space)
     throws java.lang.ArrayIndexOutOfBoundsException

ASN encoder

Overrides:

encode in class SnmpVar

Throws:

java.lang.ArrayIndexOutOfBoundsException - When there is insufficient space in buffer
