Lookup the given key from the given configuration, and provide bindings for the ScalaTrait to a class by that key.
Lookup the given key from the given configuration, and provide bindings for the ScalaTrait to a class by that key.
The end goal is to provide a binding for
ScalaTrait. The logic for finding the implementation goes like this:- If the value of the configured key is
provided, this indicates the user will provide their own binding, so return nothing. - If the value of the configured key is a class that exists, then use that - If the value of the configured key is not a class that exists, fail - Otherwise if no configuration value is found for key, then if there is a class found with namedefaultClassName, use that - Otherwise, use the classDefaultIf a class has been located, convert that to a binding, by the following rules:
- If it's a subclass of
ScalaTraitbind it directly - Otherwise, if it's a subclass ofJavaInterface, bind that toJavaInterface, and then also return a binding ofJavaAdaptertoScalaTrait- Otherwise, fail- ScalaTrait
The trait to bind
- JavaInterface
The Java interface for Java versions of the implementation
- JavaAdapter
An adapter class that depends on
JavaInterfaceand providesScalaTrait- JavaDelegate
An implementation of
JavaInterfacethat delegates toScalaTrait, for when the configured class is not an instance ofJavaInterface.- Default
The default implementation of
ScalaTraitif no user implementation has been provided- environment
The environment to load classes from
- config
The configuration
- key
The key to look up the classname from the configuration
- returns
Zero or more bindings to provide

Lookup the given key from the given configuration, and load it either as an instance of ScalaTrait, or JavaInterface.

If no user provided class can be found, then return Default.
- If the value of the configured key is
provided, this indicates the user will provide their own binding, so return None. - If the value of the configured key is a class that exists, then use that - If the value of the configured key is not a class that exists, fail - Otherwise if no configuration value is found for key, then if there is a class found with namedefaultClassName, use that - Otherwise, use the classDefaultIf a class has been located, then return Some, according to the following rules:

ScalaTraitreturn that as Left - Otherwise, if it's a subclass ofJavaInterface, return that as Right - Otherwise, fail- ScalaTrait
