2da01fb183 Deleted deepCopy as GsonBuilder should not be designed as a reusable object. 2011-11-29 07:58:32 +00:00

ec42d600af Decode JSON literal types eagerly and with our own decoder. Previously we relied on Double.parseDouble() to decode tokens. Since that method is expensive, we deferred calling it unless absolutely necessary. Now we decode the literal type immediately. For efficiency we decode the token right out of the char buffer. This makes things more complicated but it saves many calls to charAt(). It also opens up the possibility to deferring string creation. 2011-11-27 16:50:45 +00:00

852cd72059 Don't allocate a whole bunch of objects each time we deserialize a map key. This saves 20% on bug 375's benchmark.
The fix here is quite distasteful; I'm adding an ugly backdoor API for MapTypeAdapterFactory to fiddle with the internal bits of JsonReader. I'd like to revisit this sooner or later, but for now I'll take the speedup.

4c06b01369 Cache all computed type adapters. On one particularly violent test (issue 375) this improves performance by 77%. 2011-11-26 15:30:38 +00:00

ddde79c861 Added a deepCopy() method in GsonBuilder. This allows a web-service to create a pre-configured GsonBuilder and then for each request, create a Gson instance by adding type adapters to a copy.
In TypeAdapter.Factory.create() method, using the term gson to refer to the Gson instance instead of a little ambiguous context.

9a80d095d9 Fix a regression I introduced with the changes to type hierarchy registration. If the registered type was a raw type, we need to also match the parameterizations of that type. 2011-11-23 13:38:25 +00:00

1794182a56 Commit to factories as the mechanism to lookup type adapters. This uses factories for type hierarchy adapters. We keep a separate list of factories for tree-style adapters registered with registerTypeHierarchyAdapter to guarantee that these come after the non-hierarchy adapters.
This drops support for type hierarchy instance creators. I don't expect this to be a problem. We'll also detect fewer errors where multiple type adapters can serialize the same type. With APIs like getNextTypeAdapter, I think this might actually be an improvement!

d1de4cf676 renamed GsonBuilder.factory() to GsonBuilder.registerTypeAdapterFactory()
revised GsonBuilder.registerTypeAdapter/registerTypeHierarchyAdapter to take streaming type adapters as well. Removed the typeAdapter() and typeHierarchyAdapter() methods from the public API.

d1cee8443f Whoops! The TreeTypeAdapter shouldn't be public API. 2011-11-22 07:47:06 +00:00

aa2f61b7d8 Rename GsonExclusionStrategy to Excluder. The new class is its own factory, which simplifies its caller in GsonBuilder. It no longer implements ExclusionStrategy, which allows the callers to pass in a boolean for serialize/deserialize. This allows us to use one excluder for both code paths. The delegate ExclusionStrategy instances might end up not being shared so it has two lists internally. 2011-11-22 07:37:13 +00:00

fed332906d Create a single, monolithic class to manage all exclusion strategies. This gets our file size within target of 177KiB.
I intend to follow this up with a builder for our new class to avoid multiple-argument constructor calls.

4da08b0ec6 Remove two implementation classes that weren't generally useful:
- The cache interface has only one implementation. Drop the interface; we can add it back later if necessary.
 - The DefaultTypeAdapters class contains one member class. Just make that a top-level class.

7def596775 Begin to tighten the ExclusionStrategy code. This replaces named classes with anonymous classes wherever we have a single instance of a type. 2011-11-21 06:14:23 +00:00

e23973afec Smash together ReflectiveTypeAdapterFactory and its subclass. The separation was useful earlier when we were contemplating keeping Gson and MiniGson separate. 2011-11-21 05:42:30 +00:00

f89e92aa9f Tighten up some of the fields naming policy code. The main thrust of this change is replacing classes like UpperCaseNamingPolicy with the corresponding method calls. Classes like CompositeFieldNamingPolicy are replaced by sequences of method calls. This also replaces unit tests with functional tests.
One nice benefit of this is a 3%/5.7KiB reduction in the size of gson.jar to 184KiB.

d391584d48 Register Gson 1.x tree-style adapters in the TypeAdapter.Factory list rather than in the ParameterizedTypeHandlerMap.
The motivation for this change is to give tree-style adapters precedence order in registration. This fixes the test I committed earlier today, where registration order was not honored.

This renamed ParameterizedTypeHandlerMap to the shorter 'TypeMap'. For type adapters, this is now only used for type hierarchy. We still need non-hierarchy support in TypeMap for instance creators; I'll be looking for workarounds to see if further simplification is possible here.

7e760143fd Smash together MiniGson and Gson. This changes Gson to be the MiniGson rather than delegating to the MiniGson. It means that the MiniGson objects passed into streaming type adapters are now fully-capable 'Gson' objects.
The most notable impact of this change is that it adds several new public APIs:
 - The TypeAdapter abstract class
 - The TypeAdapter.Factory interface
 - Four new methods on GsonBuilder to register streaming TypeAdapters (via Factory, via Class, via TypeToken, and as a type hierarchy)
 - Three new methods on Gson to lookup streaming TypeAdapters (by type, by class, and to get the next type adapter) 

Still outstanding:
 - Write beautiful prose to document the new APIs above
 - Change GsonBuilder's precedence so that both old and new-style type adapters are registered in one lot

339d3dd4d0 The real reason for this CL is to claim commit #1000 :)
Tiny performance enhancement: Reordered type orders to move up String and Integer which are likely to be most common fields.
