2.2.4.1.1.2.1.1.1 VBAR_CACHE_HIT
The VBAR_CACHE_HIT structure is used to specify a V-Bar cache hit.
The use of this structure implies that the necessary V-Bar data is already present in the V-Bar Storage (section 3.3.1.10) ADM element at the index specified by the vBarIndex field. In this case, the shortVBarPixels field of the encapsulating CLEARCODEC_VBAR (section 2.2.4.1.1.2.1.1) structure MUST NOT be present, and the size of the data in the V-Bar Storage ADM element MUST be equal to 3 * (yEnd - yStart + 1) bytes, where yEnd and yStart are specified in the encapsulating CLEARCODEC_BAND (section 2.2.4.1.1.2.1) structure.
