Class SnmpContextv2cPool

java.lang.Object

uk.co.westhawk.snmp.stack.SnmpContextPool

uk.co.westhawk.snmp.stack.SnmpContextv2cPool

All Implemented Interfaces:

SnmpContextBasisFace, SnmpContextFace, SnmpContextv2cFace

public class SnmpContextv2cPool
extends SnmpContextPool
implements SnmpContextv2cFace

This class contains the pool of SNMP v2c contexts. It extends the SnmpContextPool and is similar in every way, except it uses a pool of SnmpContextv2c.

Method Detail

getVersion

public int getVersion()

Description copied from interface: SnmpContextBasisFace

Returns the SNMP version of the context.

Specified by:

getVersion in interface SnmpContextBasisFace

Overrides:

getVersion in class SnmpContextPool

Returns:

The version

See Also:

SnmpConstants.SNMP_VERSION_1, SnmpConstants.SNMP_VERSION_2c, SnmpConstants.SNMP_VERSION_3

getMatchingContext

protected SnmpContext getMatchingContext()
                                  throws java.io.IOException

Returns a v2c context from the pool. The pre-existing context (if there is any) is destroyed. This methods checks for an existing context that matches all our properties. If such a context does not exist, a new one is created and added to the pool. This method actually returns a SnmpContextv2c, although it doesn't look like it.

Overrides:

getMatchingContext in class SnmpContextPool

Returns:

A context (v2c) from the pool

Throws:

java.io.IOException

See Also:

SnmpContextPool.getHashKey(), SnmpContext, SnmpContextv2c

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

This method is not supported. It will throw a CloneNotSupportedException.

Specified by:

clone in interface SnmpContextBasisFace

Overrides:

clone in class SnmpContextPool

Throws:

java.lang.CloneNotSupportedException - Thrown when the constructor generates an IOException or when in one of the Pool classes.

Since:

4_14
