Detailed Description

Class Definition CPeriodicTriggerValue for LLRP parameter PeriodicTriggerValue.

• Document Reference LLRP Specification Section 10.2.1.1.1.1

• Document Reference LLRP Specification Section 16.2.4.1.1.1.1

Periodic trigger is specified using UTC time, offset and period.

For one-shot inventory, period is set to 0, and for periodic inventory operation period > 0.

If UTC time is not specified, the first start time is determined as (time of message receipt + offset), else, the first start time is determined as (UTC time + offset). Subsequent start times = first start time + k * period (where, k > 0).

If the Reader does not support UTC clock (as indicated by HasUTCClockCapability), and it receives the UTC time as part of the PeriodicTriggerValue parameter from the Client, the Reader SHALL return an error.

Member Function Documentation

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

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