Updates all service configurations of the given type.

For each existing service creation configuration instance that is assignment compatible with clazz the following process is performed:

1. The configuration is converted to its detached representations using the ServiceConfiguration.derive() method.
2. The detached representation is transformed using the update unary operator.
3. A new configuration is generated by passing the transformed detached representation to the existing configurations ServiceConfiguration.build(Object) method.
4. The new configuration is added to the builders service configuration set.

If there are no service creation configurations assignment compatible with clazz then an IllegalStateException will be thrown.

Type Parameters:

R - configuration detached representation type

C - service configuration type

Parameters:

clazz - service configuration concrete type

update - configuration mutation function

Returns:
