Enum Class IoBackendType

java.lang.Object

java.lang.Enum<IoBackendType>

org.zvec.binding.IoBackendType

All Implemented Interfaces:

Serializable, Comparable<IoBackendType>, Constable

public enum IoBackendType
extends Enum<IoBackendType>

I/O backend types used for DiskAnn disk reads (zvec ≥ v0.7.0). Maps to ZVEC_IO_BACKEND_TYPE_* in c_api.h.

On Linux, zvec selects the first usable backend in this order: IO_URING, LIBAIO, then PREAD. macOS uses PREAD. Windows uses WINDOWS_OVERLAPPED (zvec ≥ v0.8.0).

Enum Constant Details

PREAD

public static final IoBackendType PREAD

Synchronous pread(); no async I/O.

LIBAIO

public static final IoBackendType LIBAIO

libaio loaded at runtime via dlopen().

IO_URING

public static final IoBackendType IO_URING

io_uring via raw Linux kernel syscalls (zero dependency).

WINDOWS_OVERLAPPED

public static final IoBackendType WINDOWS_OVERLAPPED

Windows unbuffered overlapped I/O with a per-context completion port.

Method Details

values

public static IoBackendType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static IoBackendType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getCode

public int getCode()

fromCode

public static IoBackendType fromCode(int code)

getName

public String getName()

Human-readable backend name as reported by the native library.
