AEABuilder Objects

class AEABuilder(WithLogger)

This class helps to build an AEA.

It follows the fluent interface. Every method of the builder returns the instance of the builder itself.

Note: the method 'build()' is guaranteed of being re-entrant with respect to the 'add_component(path)' method. That is, you can invoke the building method many times against the same builder instance, and the returned agent instance will not share the components with other agents, e.g.:

builder = AEABuilder() builder.add_component(...) ...

first call

my_aea_1 = builder.build()

following agents will have different components.

my_aea_2 = builder.build() # all good

However, if you manually loaded some of the components and added them with the method 'add_component_instance()', then calling build more than one time is prevented:

builder = AEABuilder() builder.add_component_instance(...) ... # other initialization code

first call

my_aea_1 = builder.build()

second call to build() would raise a Value Error.

call reset

builder.reset()

re-add the component and private keys

builder.add_component_instance(...) ... # add private keys

second call

my_aea_2 = builder.builder()

__init__

def __init__(with_default_packages: bool = True,
             registry_dir: str = DEFAULT_REGISTRY_NAME,

  • build_dir_root: the root of the build directory.

reset

def reset(is_full_reset: bool = False) -> None
