ValidateVersion

public static void ValidateVersion()

getRootAsSparseMatrixIndexCSX

public static SparseMatrixIndexCSX getRootAsSparseMatrixIndexCSX(ByteBuffer _bb)

getRootAsSparseMatrixIndexCSX

public static SparseMatrixIndexCSX getRootAsSparseMatrixIndexCSX(ByteBuffer _bb,
                                                                 SparseMatrixIndexCSX obj)

public void __init(int _i,
                   ByteBuffer _bb)

__assign

public SparseMatrixIndexCSX __assign(int _i,
                                     ByteBuffer _bb)

compressedAxis

public short compressedAxis()

Which axis, row or column, is compressed

indptrType

public Int indptrType()

The type of values in indptrBuffer

indptrType

public Int indptrType(Int obj)

indptrBuffer

public Buffer indptrBuffer()

indptrBuffer stores the location and size of indptr array that represents the range of the rows. The i-th row spans from `indptr[i]` to `indptr[i+1]` in the data. The length of this array is 1 + (the number of rows), and the type of index value is long. For example, let X be the following 6x4 matrix: ```text X := [[0, 1, 2, 0], [0, 0, 3, 0], [0, 4, 0, 5], [0, 0, 0, 0], [6, 0, 7, 8], [0, 9, 0, 0]]. ``` The array of non-zero values in X is: ```text values(X) = [1, 2, 3, 4, 5, 6, 7, 8, 9]. ``` And the indptr of X is: ```text indptr(X) = [0, 2, 3, 5, 5, 8, 10]. ```

indptrBuffer

public Buffer indptrBuffer(Buffer obj)

indicesType

public Int indicesType()

The type of values in indicesBuffer

indicesType

public Int indicesType(Int obj)

indicesBuffer

public Buffer indicesBuffer()

indicesBuffer stores the location and size of the array that contains the column indices of the corresponding non-zero values. The type of index value is long. For example, the indices of the above X is: ```text indices(X) = [1, 2, 2, 1, 3, 0, 2, 3, 1]. ``` Note that the indices are sorted in lexicographical order for each row.
