Detailed Description

Represents a TimeTicks as described in RFC 2741.

Definition at line 33 of file TimeTicksVariable.hpp.

Constructor & Destructor Documentation

agentxcpp::TimeTicksVariable::TimeTicksVariable ( quint32 initial_value = 0 )

inline

(Default) constructor.

Parameters

initial_value The initial value of the object.

Definition at line 58 of file TimeTicksVariable.hpp.

TimeTicksVariable::TimeTicksVariable	(	binary::const_iterator &	pos,
		const binary::const_iterator &	end,
		bool	big_endian = `true`
	)

Parse Constructor.

This constructor parses the serialized form of the object. It takes an iterator, starts parsing at the position of the iterator and advances the iterator to the position right behind the object.

The constructor expects valid data from the stream; if parsing fails, parse_error is thrown. In this case, the iterator position is undefined.

Parameters

pos	Iterator pointing to the current stream position. The iterator is advanced while parsing.
end	Iterator pointing one element past the end of the current stream. This is needed to avoid buffer overrun.
big_endian	Whether the input stream is in big endian format.

Member Function Documentation

virtual void agentxcpp::TimeTicksVariable::handle_cleanupset ( )

inlinevirtual

Handle a CleanupSet request.

This function calls perform_cleanupset() with the internal value of new_value (which was updated by the last handle_testset() invocation).

Implements agentxcpp::AbstractVariable.

Definition at line 151 of file TimeTicksVariable.hpp.

References perform_cleanupset().

virtual bool agentxcpp::TimeTicksVariable::handle_commitset ( )

inlinevirtual

Handle a CommitSet request.

This function calls perform_commitset() with the internal value of new_value (which was updated by the last handle_testset() invocation).

Returns: The return value of perform_commitset().

Implements agentxcpp::AbstractVariable.

Definition at line 169 of file TimeTicksVariable.hpp.

References perform_commitset().

virtual void agentxcpp::TimeTicksVariable::handle_get ( )

inlinevirtual

Handle a Get Request.

This function calls perform_get() to update the internal value.

Implements agentxcpp::AbstractVariable.

Definition at line 105 of file TimeTicksVariable.hpp.

References perform_get().

virtual testset_result_t agentxcpp::TimeTicksVariable::handle_testset ( QSharedPointer< AbstractVariable > _v )

inlinevirtual

Handle a TestSet request.

This function converts the argument, stores it in new_value and then calls perform_testset() with the internal value of new_value. If conversion fails, AbstractVariable::wrongType is returned and perform_testset() is not called.

Parameters

_v	The new value for the variable.

Returns: AbstractVariable::wrongType if the conversion fails. Otherwise, the result of perform_testset() is returned.

Implements agentxcpp::AbstractVariable.

Definition at line 122 of file TimeTicksVariable.hpp.

References perform_testset(), and agentxcpp::AbstractVariable::wrongType.

virtual bool agentxcpp::TimeTicksVariable::handle_undoset ( )

inlinevirtual

Handle an UndoSet request.

This function calls perform_undoset() with the internal value of new_value (which was updated by the last handle_testset() invocation).

Returns: The return value of perform_undoset().

Implements agentxcpp::AbstractVariable.

Definition at line 186 of file TimeTicksVariable.hpp.

References perform_undoset().

virtual void agentxcpp::TimeTicksVariable::perform_cleanupset ( quint32 _v )

inlinevirtual

Perform an SNMP CleanupSet request.

This method is invoked when an SNMP CleanupSet request is received. It shall release any resources allocated by perform_testset().

The default implementation does nothing. If no action is required to perform the CleanupSet operation, this method need not be overridden.

Parameters

_v	The value to which the variable was (possibly) set.

Definition at line 159 of file TimeTicksVariable.hpp.

Referenced by handle_cleanupset().

virtual bool agentxcpp::TimeTicksVariable::perform_commitset ( quint32 _v )

inlinevirtual

Perform an SNMP CommitSet request.

This method is invoked when an SNMP CommitSet request is received. It shall perform the actual write operation.

The default implementation returns false to indicate that the operation failed. To implement a writeable SNMP variable this method must be overridden.

Parameters

_v	The value which shall be written.

Returns: True if the operation succeeded, false otherwise.

Definition at line 176 of file TimeTicksVariable.hpp.

Referenced by handle_commitset().

virtual void agentxcpp::TimeTicksVariable::perform_get ( )

inlinevirtual

Perform a Get request.

This method is invoked when an SNMP Get request is received. It should update the internal value v.

Definition at line 113 of file TimeTicksVariable.hpp.

Referenced by handle_get().

virtual testset_result_t agentxcpp::TimeTicksVariable::perform_testset ( quint32 _v )

inlinevirtual

Perform an SNMP TestSet request.

This method is invoked when an SNMP TestSet request is received. It shall check whether a Set operation is possible for the variable. It shall acquire the resources needed to perform the Set operation (but the Set operation shall not yet be performed).

The default implementation returns AbstractVariable::noAccess to indicate that this is a read-only variable. Thus, for read-only variables this method need not be overridden.

Parameters

_v	The new value provided by the master agent.

Returns: The result of the check (this is reported to the master agent).

Definition at line 141 of file TimeTicksVariable.hpp.

References agentxcpp::AbstractVariable::noAccess.

Referenced by handle_testset().

virtual bool agentxcpp::TimeTicksVariable::perform_undoset ( quint32 _v )

inlinevirtual

Perform an SNMP UndoSet request.

This method is invoked when an SNMP UndoSet request is received. It shall undo whatever perform_commitset() performed. It shall also release all resources allocated by perform_testset(), because perform_cleanupset() will not be called afterwards.

The default implementation returns false to indicate that the operation failed. It is strongly recommended that writeable variables override this method.

A default implementation is provided to allow implementing read-only variables.

Parameters

_v	The value just set by perform_commitset().

Returns: True on success, false otherwise.

binary TimeTicksVariable::serialize ( ) const

virtual

Encode the object as described in RFC 2741, section 5.4.

This function uses big endian.

Implements agentxcpp::AbstractVariable.

Definition at line 25 of file TimeTicksVariable.cpp.

References v, and agentxcpp::write32().

void agentxcpp::TimeTicksVariable::setValue ( quint32 _value )

inline

Set the value.

Parameters

_value The new value.

Definition at line 85 of file TimeTicksVariable.hpp.

virtual Oid agentxcpp::TimeTicksVariable::toOid ( ) const

inlinevirtual

Convert the value to an OID.

The conversion is done according to RFC 2578, 7.7. "Mapping of the INDEX clause". The value is converted to an Oid with a single subid.

This method should not be overridden.

Note: If a TIMETICK is used in an INDEX clause, the value 0 should be avoided according to RFC 2578, 7.7. "Mapping of the INDEX clause".

Implements agentxcpp::AbstractVariable.

Definition at line 212 of file TimeTicksVariable.hpp.

quint32 agentxcpp::TimeTicksVariable::value ( )

inline

Get the current value.

Returns: The value.

Definition at line 95 of file TimeTicksVariable.hpp.

Member Data Documentation

QSharedPointer<TimeTicksVariable> agentxcpp::TimeTicksVariable::new_value

private

The new value for the variable. Used during a Set operation.

The Set operation is performed in up to four steps (TestSet, CommitSet, CleanupSet, UndoSet). Only the TestSet step actually receives the new value. This value is stored here so that it can be delivered to perform_commitset(), perform_undoset() and perform_cleanupset().

Definition at line 49 of file TimeTicksVariable.hpp.

quint32 agentxcpp::TimeTicksVariable::v

protected

The TimeTicks value.

According to RFC 2578, TimeTicks is a non-negative 32-bit number.
