getRootAsRecordBatch

public static RecordBatch getRootAsRecordBatch(ByteBuffer _bb)

getRootAsRecordBatch

public static RecordBatch getRootAsRecordBatch(ByteBuffer _bb,
                                               RecordBatch obj)

__init

public void __init(int _i,
                   ByteBuffer _bb)

__assign

public RecordBatch __assign(int _i,
                            ByteBuffer _bb)

length

public long length()

number of records / rows. The arrays in the batch should all have this length

nodes

public FieldNode nodes(int j)

Nodes correspond to the pre-ordered flattened logical schema

nodes

public FieldNode nodes(FieldNode obj,
                       int j)

nodesLength

public int nodesLength()

buffers

public Buffer buffers(int j)

Buffers correspond to the pre-ordered flattened buffer tree The number of buffers appended to this list depends on the schema. For example, most primitive arrays will have 2 buffers, 1 for the validity bitmap and 1 for the values. For struct arrays, there will only be a single buffer for the validity (nulls) bitmap

buffers

public Buffer buffers(Buffer obj,
                      int j)

buffersLength

public int buffersLength()

createRecordBatch

                                    long length,
                                    int nodesOffset,
                                    int buffersOffset)
