• free(): void

intoFFI

• intoFFI(): FFIRecordBatch

• Export this RecordBatch to FFI structs according to the Arrow C Data Interface.

  This method does consume the RecordBatch, so the original RecordBatch will be inaccessible after this call. You must still call FFIRecordBatch.free after you've finished using the FFIRecordBatch.

  Returns FFIRecordBatch

intoIPCStream

• intoIPCStream(): Uint8Array

• Consume this RecordBatch and convert to an Arrow IPC Stream buffer

  Returns Uint8Array

toFFI

• toFFI(): FFIRecordBatch

• Export this RecordBatch to FFI structs according to the Arrow C Data Interface.

  This method does not consume the RecordBatch, so you must remember to call RecordBatch.free to release the resources. The underlying arrays are reference counted, so this method does not copy data, it only prevents the data from being released.

  Returns FFIRecordBatch
