Detailed Description

Class Definition CLLRPConfigurationStateValue for LLRP parameter LLRPConfigurationStateValue.

• Document Reference LLRP Specification Section 12.2.1

• Document Reference LLRP Specification Section 16.2.6.1

This parameter, LLRPConfigurationStateValue, is a 32-bit value which represents a Reader's entire LLRP configuration state including: LLRP configuration parameters, vendor extension configuration parameters, ROSpecs, and AccessSpecs. A Reader SHALL change this value only:

• Upon successful execution of any of the following messages: ADD_ROSPEC, DELETE_ROSPEC, ADD_ACCESSSPEC, DELETE_ACCESSSPEC, SET_READER_CONFIG, or any CUSTOM_MESSAGE command that alters the reader's internal configuration.

• Upon an automatically deleted AccessSpec due to completion of OperationCountValue number of operations (Section 11.2.1.1).

A Reader SHALL not change this value when the CurrentState of a ROSpec or AccessSpec changes.

The mechanism used to compute the LLRP configuration state value is implementation dependent. However, a good implementation will insure that there's a high probability that the value will change when the Reader's configuration state changes.

It is expected that a Client will configure the Reader and then request the Reader's configuration state value. The Client will then save this state value. If this value does not change between two requests for it, then a Client may assume that the above components of the LLRP configuration have also not changed.

When requested by a Client, the Reader SHALL compute a state value based upon the Reader's current configuration state. Upon each request, the Reader SHALL return the same state value provided a Client has not altered the Reader's configuration state between requests. Aside from this requirement, the computation of the state value is implementation dependent.

Member Function Documentation

void LLRP::CLLRPConfigurationStateValue::assimilateSubParameters (  CErrorDetails *  pError  )  [virtual]

Assimilates the decoded sub-parameters into m_listAllSubParameters. After fields are decoded, the CDecoder itself takes care of gathering the subparameters into m_listAllSubParameters. Once the end of the enclosing TLV (or message) is reached this assimilateSubParameters() function is called to create parameter refrences from the primary member variables. Parameters: [out]  pError  Error details for encoded stream Implements LLRP::CElement.

void LLRP::CLLRPConfigurationStateValue::decodeFields (  CDecoderStream *  pDecoderStream  )  [virtual]

Virtual function provided by each specific element type to decode fields (simple values). Leaves pDecoderStream at first subparameter. Parameters: [in]  pDecoderStream  The stream from which to decode fields Returns: void Implements LLRP::CElement.

void LLRP::CLLRPConfigurationStateValue::encode (  CEncoderStream *  pEncoderStream  )  const [virtual]

Encode fields and subparameters. Parameters: [in]  pEncoderStream  Stream to encode Returns: void Implements LLRP::CElement.
