| /** |
| * This is a container class for configurable objects in build.gradle files like signing configs, flavors, build types, and the like. |
| * These are named entities that live inside a parent closure, like buildType1 and buildType2 in this example: |
| * <p> |
| * <code> |
| * android { |
| * buildTypes { |
| * buildType1 { |
| * someProperty "someValue" |
| * anotherProperty "anotherValue" |
| * } |
| * buildType2 { |
| * someProperty "differentValue" |
| * anotherProperty "anotherDifferentValue" |
| * } |
| * } |
| * } |
| * </code> |
| * |
| * <p> |
| * These objects are syntactically method calls in Groovy; the method name is the object's name, and the argument is a closure that |
| * takes property/value statements (which are themselves method calls). |
