Detailed Description

Class Definition CImpinjTagDirection for LLRP parameter ImpinjTagDirection.

This custom parameter conveys the direction of a tag through a portal with an associated confidence factor. If tag direction is enabled using the ImpinjTagDirectionReporting parameter, the Reader will send RO_ACCESS_REPORT messages containing direction information whenever a direction decision has been made or the confidence factor changes.

As it is impossible to define direction without a frame of reference, tag direction is reported by using abstract sides 1 and 2 as reference points. The actual definition corresponding to the values reported by the Reader are determined by the physical cabling of the antennas to the Reader. Specifically, for a dual antenna configuration, side 1 is defined as the direction of the antenna connected to the Antenna 1 BNC and side 2 is defined as the direction of the antenna connected to the Antenna 2 BNC. For the quad antenna configuration, side 1 is antennas 1 and 3, and side 2 is antennas 2 and 4.

Member Function Documentation

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

Encode fields and subparameters.

Parameters:
[in] pEncoderStream Stream to encode
Returns:
void

Implements LLRP::CElement.

llrp_bool_t LLRP::CImpinjTagDirection::isAllowedIn ( const CTypeDescriptor pEnclosingTypeDescriptor  )  const [virtual]

Validate whether the element is allowed as a base type in the enclosing element.

Parameters:
[in] pEnclosingTypeDescriptor A pointer to the enclosing type
Returns:
TRUE if the element is allowed to be encoded within the EnclosingElement

FALSE if the element is not allowed to be encoded within the EnclosingElement

Reimplemented from LLRP::CParameter.
