Interface LinearAlgebraBackend<E>

Type Parameters:

E - the element type supported by this backend (e.g., Real, Double)

All Superinterfaces:

AlgorithmProvider, AutoCloseable, Backend, ComputeBackend, LinearAlgebraProvider<E>

All Known Implementing Classes:

CPUSparseLinearAlgebraProvider, GRPCLinearAlgebraBackend

public interface LinearAlgebraBackend<E>
extends ComputeBackend, LinearAlgebraProvider<E>

Interface for linear algebra backends. Combines general backend metadata with linear algebra implementation details.

Method Summary

Modifier and Type	Method	Description
default String	getName()	Returns the display name for UI presentation.
default int	getPriority()	Returns the priority for auto-selection (higher = preferred).
default String	getType()	Returns the backend type category (e.g., "plotting", "molecular", "tensor", "math").
default boolean	isAvailable()	Checks if this backend is currently available (libraries loaded, etc.).
default void	shutdown()	Called when the application is shutting down or the backend is being replaced.

Method Details

getType

default String getType()

Description copied from interface: Backend

Returns the backend type category (e.g., "plotting", "molecular", "tensor", "math").

Specified by:

getType in interface Backend

Specified by:

getType in interface ComputeBackend

getName

default String getName()

Description copied from interface: Backend

Returns the display name for UI presentation.

Specified by:

getName in interface AlgorithmProvider

Specified by:

getName in interface Backend

Specified by:

getName in interface LinearAlgebraProvider<E>

getPriority

default int getPriority()

Description copied from interface: Backend

Returns the priority for auto-selection (higher = preferred). Used when multiple backends are available.

Specified by:

getPriority in interface AlgorithmProvider

Specified by:

getPriority in interface Backend

Specified by:

getPriority in interface LinearAlgebraProvider<E>

isAvailable

default boolean isAvailable()

Description copied from interface: Backend

Checks if this backend is currently available (libraries loaded, etc.).

Default implementation checks Backend.isExplicitlyDisabled() and returns false if it is.

Specified by:

isAvailable in interface AlgorithmProvider

Specified by:

isAvailable in interface Backend

shutdown

default void shutdown()

Description copied from interface: Backend

Called when the application is shutting down or the backend is being replaced. Use this to release hardware resources, close file handles, or stop background threads.

Specified by:

shutdown in interface AlgorithmProvider

Specified by:

shutdown in interface Backend
