qat.plugins.AbstractPlugin

class qat.plugins.AbstractPlugin(*args, **kwargs)

Abstract interface of a Plugin.

post_process(batch_result)

A plugin can optionally post-process a result. Post-processing consists of editing the BatchResult object returned by the QPU

Note

If your plugin does not require prost-processing, not defining this method would lead to better performances

Parameters

batch_result (BatchResult) – object to be post-processed

Returns

post-processed BatchResult

Return type

BatchResult

abstract compile(batch, specs)

Compiles a Batch into another Batch according to some hardware specs

Parameters

• batch (Batch) – batch to compile

• specs (HardwareSpecs) – hardware specs

Returns

compiled batch

Return type

Batch

do_post_processing()

Returns True iff the results need to be aggregated/post processed via the plugin.

Returns

Is post-processing needed?

Return type

bool

serve(port, host_ip='localhost', server_type=None, ssl_cert: Optional[str] = None, ssl_key: Optional[str] = None, ssl_ca: Optional[str] = None)

Runs the plugin inside a server

Parameters

• port (int) – the port on which to listen

• host_ip (str) – the url on which to publish the API. Optional. Defaults to ‘localhost’.

• server_type (str, optional) –

• ssl_cert (str, optional) – path to the server SSL certificate (mandatory for SSL) Default: None

• ssl_key (str, optional) – path to the server SSL key (mandatory for SSL) Default: None

• ssl_ca (str, optional) – path to the server SSL certificate authority (only serves requests with signed certificates) Default: None
