Method Details

create

public A2AHttpClient create()

Description copied from interface: A2AHttpClientProvider

Creates a new instance of an A2AHttpClient.

Specified by:

create in interface A2AHttpClientProvider

Returns:

a new A2AHttpClient instance

createWithSseConfig

public A2AHttpClient createWithSseConfig(SSEParserConfig sseParserConfig)

Creates a new instance of an A2AHttpClient with the given SSEParserConfig.

Providers that support SSE parser configuration should override both this method and A2AHttpClientProvider.supportsSseConfig() to return true. The default implementation ignores sseParserConfig and delegates to A2AHttpClientProvider.create().

Specified by:

createWithSseConfig in interface A2AHttpClientProvider

Parameters:

sseParserConfig - the SSE parser configuration to apply

Returns:

a new A2AHttpClient instance

supportsSseConfig

public boolean supportsSseConfig()

Description copied from interface: A2AHttpClientProvider

Returns true if this provider honours the SSEParserConfig passed to A2AHttpClientProvider.createWithSseConfig(SSEParserConfig).

Providers that override A2AHttpClientProvider.createWithSseConfig(SSEParserConfig) to actually apply the configuration must also override this method and return true; the A2AHttpClientFactory.createWithSseConfig(SSEParserConfig) method uses this flag to skip providers that would silently ignore the supplied configuration.

The default is false, matching the default no-op implementation of A2AHttpClientProvider.createWithSseConfig(SSEParserConfig).

Specified by:

supportsSseConfig in interface A2AHttpClientProvider

Returns:

true if this provider applies the given SSEParserConfig

priority

public int priority()

Description copied from interface: A2AHttpClientProvider

Returns the priority of this provider. Higher priority providers are tried first; the first one whose A2AHttpClientProvider.create() succeeds is used.

Built-in priorities (for reference when choosing a custom value):

• CdiA2AHttpClient: 200 (CDI-provided bean, when a container and bean are active)
• AndroidA2AHttpClient: 110 (Android runtime only)
• VertxA2AHttpClient: 100 (when vertx-web-client is on the classpath)
• JdkA2AHttpClient: 0 (always available, last resort)

Specified by:

priority in interface A2AHttpClientProvider

Returns:

the priority value (higher is better)

name

public String name()

Description copied from interface: A2AHttpClientProvider

Returns the name of this provider for logging and debugging purposes.

Specified by:

name in interface A2AHttpClientProvider

Returns:

the provider name
