public class SnmpUInt32
extends Object
implements SnmpSyntax, Cloneable, Serializable
```
This class defines the 32-bit unsigned SNMP object used to transmit 32-bit unsigned number. The unsigned value is represented by a 64-bit quantity, but the upper 32-bits are always truncated from the value. If a caller passes in a value with any the upper 32-bits set the value will be silently truncated to a 32-bit value. If negative quantities or values with more than 32-bits are passed then data corruption will occur.

  - ASNTYPE
```
public static final byte ASNTYPE
```
    The ASN.1 value for an unsigned integer value. BEWARE this value will conflict with the SnmpSMI.SMI_COUNTER32 value. This object should not be dynamically registered with the SNMP library

- Constructor Detail
  - SnmpUInt32
```
public SnmpUInt32()
```
    Default class constructor. Constructs the object with a value of zero(0).
  - SnmpUInt32
```
public SnmpUInt32(long value)
```
    Constructs a SnmpUInt32 object with the specified value.
    
    Parameters:
    
    value - The new 32-bit value.
  - SnmpUInt32
```
public SnmpUInt32(Long value)
```
    Constructs a SnmpUInt32 object with the specified value.
    
    Parameters:
    
    value - The new 32-bit value.
  - SnmpUInt32
```
public SnmpUInt32(SnmpUInt32 second)
```
    Class copy constructor. Constructs a new object with the same value as the passed object.
    
    Parameters:
    
    second - The object to copy the value from.
  - SnmpUInt32
```
public SnmpUInt32(String value)
```
    Simple class constructor that recovers the unsigned value from the passed string. If the decoded value evaluates to a negative number or is malformed then an exception is generated. Likewise, the argument must not be a null reference or a null pointer exception is generated by the constructor.
    
    Parameters:
    
    value - The unsigned value encoded as a string.
    
    Throws:
    
    NullPointerException - Thrown if the passed value is a null pointer.
    
    IllegalArgumentException - Thrown if the decoded value evaluates to a negative value.
    
    NumberFormatException - Throws in the passed value cannot be decoded by the constructor.

  - getValue
```
public long getValue()
```
    Used to retreive the 32-bit unsigned value.
    
    Returns:
    
    The internal 32-bit value.
  - setValue
```
public void setValue(long value)
```
    Used to set the 32-bit unsigned quantity. If the value exceeds 32-bit then the upper 32-bits will be silently truncated from the value.
    
    Parameters:
    
    value - The new value for the object
  - setValue
```
public void setValue(Long value)
```
    Used to set the 32-bit unsigned quantity. If the value exceeds 32-bit then the upper 32-bits will be silently truncated from the value.
    
    Parameters:
    
    value - The new value for the object
  - typeId
```
public byte typeId()
```
    Used to retreive the ASN.1 type for this object.
    
    Specified by:
    
    typeId in interface SnmpSyntax
    
    Returns:
    
    The ASN.1 value for the SnmpUInt32
  - encodeASN
```
public int encodeASN(byte[] buf,
                     int offset,

              throws AsnDecodingException
```
    Used to decode the integer value from the ASN.1 buffer. The passed encoder is used to decode the ASN.1 information and the integer value is stored in the internal object.
