public uint GetSeqIndex( uint d0, uint d1, uint d2, uint d3, uint d4, uint d5 )
Public Function GetSeqIndex ( d0 As UInteger, d1 As UInteger, d2 As UInteger, d3 As UInteger, d4 As UInteger, d5 As UInteger ) As UInteger Dim instance As Size Dim d0 As UInteger Dim d1 As UInteger Dim d2 As UInteger Dim d3 As UInteger Dim d4 As UInteger Dim d5 As UInteger Dim returnValue As UInteger returnValue = instance.GetSeqIndex(d0, d1, d2, d3, d4, d5)
Index into the first dimension.
Index into the second dimension.
Index into the third dimension.
Index into the fourth dimension.
Index into the fives dimension.
Index into the sixth dimension.
Sequential index into the array when stored as 1D array of arbitrary storage order.
|if any of the leading dimension specifiers d0 ... d4 is equal or greater than the length of its corresponding dimension.|
|if d5 is equal or greater than the length of the last dimension and the resulting index after merging trailing dimensions points to a non-existing element.|
For arrays of matrix shape d0 references the index of the row and d1 references the index of the column of the sequential index to return.
More general, for n-dimensional arrays the first index corresponds to the position in the first (index: 0) dimension, the second index to the position of the element in the second dimension (index: 1) and so forth ...
If the array addressed by this size has less dimensions than addressed by this function, trailing indices (i.e.: such indices which deal with a dimension whose index is higher than existing in the array) correspond to 'virtual' or singleton dimensions. Those indices must address the 0-th element of the virtual dimension. Hence its value must be 0.
Conversely, if the array addressed by this size stores more dimensions than addressed by this function the last index parameter d5 may exceeds the limit of its corresponding dimension. In this case the sequential index returned is computed by subsequently merging trailing dimensions and folding the superflous modulus of the value of d5 to the next dimension, correspondingly. This process is repeated until either the number of dimensions is reached or the modified new value of d5 reaches 0.
This function recognizes arbitrarily strided size objects. It expects all sizes (dimension lengths, strides, the base offset and the number of elements) to fit into. Use one of the overloads with parameters if you are dealing with very big arrays or negative indices.
Performance hint: this function (and all corresponding overloads) are optimized for the case where the number of index parameters provided corresponds to the number of dimensions in the array and all provided index parameters are within the range of their corresponding dimension. The functions, however, handle arbitrary cases, including addressing, merging and ommitting trailing dimensions. Any of those extended features may introduce a performance penalty, though.
