getRootAsSparseMatrixIndexCSR

public static SparseMatrixIndexCSR getRootAsSparseMatrixIndexCSR(ByteBuffer _bb)

getRootAsSparseMatrixIndexCSR

public static SparseMatrixIndexCSR getRootAsSparseMatrixIndexCSR(ByteBuffer _bb,
                                                                 SparseMatrixIndexCSR obj)

__init

public void __init(int _i,
                   ByteBuffer _bb)

__assign

public SparseMatrixIndexCSR __assign(int _i,
                                     ByteBuffer _bb)

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: 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: values(X) = [1, 2, 3, 4, 5, 6, 7, 8, 9]. And the indptr of X is: indptr(X) = [0, 2, 3, 5, 5, 8, 10].

indptrBuffer

public Buffer indptrBuffer(Buffer 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: indices(X) = [1, 2, 2, 1, 3, 0, 2, 3, 1].

public static void addIndicesBuffer(com.google.flatbuffers.FlatBufferBuilder builder,
                                    int indicesBufferOffset)
