public AgentCardValidator()

Method Details

resolveAndValidateOnce

public static AgentCard resolveAndValidateOnce(jakarta.enterprise.inject.Instance<AgentCard> agentCardInstance,
 AtomicBoolean transportValidated)

Resolves an AgentCard from the given Instance and validates its transport configuration exactly once using the default validateTransportConfiguration(org.a2aproject.sdk.spec.AgentCard) check. The transportValidated guard is reset on failure so validation can be retried on the next call.

Parameters:

agentCardInstance - the CDI instance holding the agent card

transportValidated - atomic guard ensuring validation runs once

Returns:

the resolved agent card

resolveAndValidateOnce

public static AgentCard resolveAndValidateOnce(Supplier<AgentCard> agentCardSupplier,
 AtomicBoolean transportValidated,
 Consumer<AgentCard> validator)

Obtains an AgentCard from the given supplier and applies the provided validator exactly once. The transportValidated guard is reset on failure so validation can be retried on the next call.

Parameters:

agentCardSupplier - supplier that produces the agent card

transportValidated - atomic guard ensuring validation runs once

validator - validation logic to apply on first access

Returns:

the resolved agent card

validateTransportConfiguration

public static void validateTransportConfiguration(AgentCard agentCard)

Validates the transport configuration of an AgentCard against available transports found on the classpath. Logs warnings for missing transports and errors for unsupported transports.

Parameters:

agentCard - the agent card to validate
