Class AlgorithmExecutionCapabilities

java.lang.Object

zeroecho.core.spi.AlgorithmExecutionCapabilities

public final class AlgorithmExecutionCapabilities
extends Object

Immutable deterministic snapshot of installed execution capabilities.

Multiple implementations may support one semantic identity. Callers must select an implementation explicitly when more than one remains after policy; classpath or provider order never supplies precedence.

Constructor Details

AlgorithmExecutionCapabilities

public AlgorithmExecutionCapabilities(List<AlgorithmExecutionCapability> capabilities)

Creates a validated immutable snapshot.

Parameters:

capabilities - installed trusted-code capabilities

Throws:

IllegalArgumentException - if implementation identifiers collide or a fingerprint is blank

Method Details

installed

public static AlgorithmExecutionCapabilities installed()

Discovers installed providers using the existing ServiceLoader convention.

Returns:

deterministic immutable capability snapshot

fromProviders

public static AlgorithmExecutionCapabilities fromProviders(Collection<? extends AlgorithmExecutionCapabilityProvider> providers)

Builds one deterministic snapshot from already selected trusted providers.

Parameters:

providers - provider instances belonging to the runtime graph

Returns:

immutable capability snapshot

supporting

public List<AlgorithmExecutionCapability> supporting(AlgorithmIdentity identity,
 AlgorithmSuite suite,
 AlgorithmExecutionCapability.Direction direction)

Finds all installed implementations supporting an exact tuple.

Parameters:

identity - exact operation identity

suite - complete suite

direction - operation direction

Returns:

deterministic immutable matching list

all

public List<AlgorithmExecutionCapability> all()

Returns the immutable installed snapshot.

Returns:

capabilities sorted by implementation identifier
