# "Component Factories" sections define utility by mapping from an import |
| |
# string for an interface (or other configuration key, to an expression |
| |
# that returns the factory (or an import string thereof). |
| |
|
| |
# Factories described here are not actually registered with the configuration |
| |
# map until the module named on the left side of the '=' is first imported. If |
| |
# the module is already imported when a "Component Factories" section is |
| |
# processed, then registration takes place immediately. |
| |
|
| |
# Keys listed here are registered twice, like this: |
| |
# key = importString(key) |
| |
# pMap.registerProvider(config.FactoryFor(key), config.ruleForExpr(value)) |
| |
# pMap.registerProvider(key, config.CreateViaFactory(key)) |
| |
|
| |
# This means that looking up a key listed here will use a 'CreateViaFactory' |
| |
# rule to invoke the factory once and return that result for all subsequent |
| |
# lookups. Looking up 'config.FactoryFor(key)' will return the factory listed |
| |
# here on the right side of the '=' sign. Thus, using 'binding.Make(key)' will |
| |
# create a private instance of the desired component, and 'binding.Obtain(key)' |
| |
# will retrieve a shared instance. |
| |
|
| |
# Note, by the way, that the items named on the left of the '=' do not have to |
| |
# be interfaces, although that is the most common usage. They may be any |
| |
# object that supports 'config.IConfigKey'. |
| |
|
| # "Provide Utilities" sections define utilities by mapping from an import |
|
| # string for an interface, to an expression defining the Provider. |
|
| # |
|
| # Note that unlike property sections, code in "Provide utilities" sections is |
|
| # executed immediately to create a provider rule, not on-demand when the |
|
| # utility is actually requested, so you should avoid code that does unnecessary |
|
| # importing. You'll notice that most providers shown here do their imports |
|
| # inside of lambdas within config.provideInstance() or |
|
| # config.instancePerComponent() calls. |
|
| |
|
| # This first provider associates a default transaction service with the |
|
| # nearest AppConfig above the object that the service is wanted for. It |
|
| # creates a TransactionService instance with that config as its parent |
|
| # component. |
