LogFactory also offers a static method getLog() that combines the typical two-step pattern: Log log = LogFactory.getFactory().getInstance("Foo"); into a single method call: Log log = LogFactory.getLog("Foo"); For example, you might use the following technique to initialize and use a Log instance in an application component: import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyComponent { protected static Log log = LogFactory.getLog("my.component"); // Called...

// and then returns a CNAME record. In our case, we preemptively store these random dns names as a host
// in the lookup table with a CNAME record as the DNS response. This technique eliminates the need
// to do string parsing, memory allocations, etc. at query time at the cost of Nx number of entries (i.e. memory) to store
// the lookup table, where N is number of search namespaces.

If a more complicated structure is required (version catalogs imported from multiple files), it's advisable to use a code-based approach, instead of TOML file.

This technique can therefore be used to declare multiple catalogs from different files:

also offers a static method getLog() that combines the typical two-step pattern: Log log = LogFactory.getFactory().getInstance(Foo.class); into a single method call: Log log = LogFactory.getLog(Foo.class); For example, you might use the following technique to initialize and use a Log instance in an application component: import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyComponent { protected static Log log = LogFactory.getLog(MyComponent.class); //...

Here is an example that uses multiple `from()` specifications, each with a different argument type.
You will probably also notice that `into()` is configured lazily using a closure (in Groovy) or a Provider (in Kotlin) — a technique that also works with `from()`:
