Where an enum value is used as an event type, it should be alllowercase (to follow DOM events). Property names should be ALLUPPERCASE in this case (just as camelCase and PascalCase are converted to CONSTANT_CASE).
Any event target can be used to dispatch generic goog.events.Event instances with an arbitrary type. In cases where we dispatch custom events, we should not use type values that collide with those used for generic events (at least internally). This allows listeners a better chance of knowing what kind of argument they will receive.
As subsequent change will clean up the enumeration and add a bit more consistency.
If you know ahead of time that you only want to listen for changes for a specific property, the foo:change type events can be useful. If you want to listen for changes on all properties, the change event becomes more useful if it provides information on what changed. And the beforechange event allows listeners to access values before they change.
This is another attempt to bring master closer to the
vector-api branch. In anticipation of the ability to keep track
of modifications on ol.Object through a beforechange event
(d7e4be0), we will be able to manage originals on the
application level or in a separate component outside of
ol.Feature.
This reduces the API footprint of versioned parsers, because
only the base parser needs to be exported as symbol, and
versioned parsers can be accessed using the getParser() method.
This change also adds some type annotations for better type
checking, introduces different write options for writing
transactions and queries, and provides new writeGetFeature and
writeTransaction methods.
Instead of setting a dummy namespace, we can have setter methods
for the featureNS property to propagate them to sub-parsers. The
srsName is also a property which needs to be propagated to
sub-parsers.
This adds a bit more inconsistency to the library, but we didn't have complete consistency before. Almost all existing string enum values are lowercase (a couple are camelCase and one is dash-separated). The closure library isn't consistent either (with case for enum properties or values). I imagine this could be justified in saying someone could blindly use GeoJSON type values in places, but in the end, you'll need to read the docs before guessing right.
