Class IOContext

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.arrow.IOContext

All Implemented Interfaces:

AutoCloseable

Direct Known Subclasses:

AsyncContext

@Namespace(value="arrow::io")
 @NoOffset
 @Properties(inherit=arrow.class)
public class IOContext
extends Pointer

EXPERIMENTAL: options provider for IO tasks Includes an Executor (which will be used to execute asynchronous reads), a MemoryPool (which will be used to allocate buffers when zero copy reads are not possible), and an external id (in case the executor receives tasks from multiple sources and must distinguish tasks associated with this IOContext).
