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()
