Generates and inflates objects provided tagged data.
Work in progress.
Current (unoptimized) benchmarks:
- 771 us/obj for full generation of a type+object (element tree, expression compilation, and object creation).
- 222 ns/obj for object creation only.
Current details:
- built on .NET Core 3.1
- run "dotnet test" to execute the nUnit tests from command line.
These are the core internal commands the public API will run on:
ElementGenerator.Create<ObjectType>()is the main entry-point for creating the Element tree.ConstructionVisitoris passed to the Element tree to create the Expression tree.ConstructionVisitor.GetResult<DataType, ObjectType>to retrieve the compiled lambda.
Currently supports:
- Data formatted as an
IDictionary<string, object>where the strings are the data ids.objects can be nested dictionaries.
- Unboxing for value-types is supported.
- Implicit and explicit conversion operators on the target type are supported. The run-time
type of the data object must match the parameter of a conversion operator, otherwise
a raw cast is used as the default. This means assigning a boxed value-type to another type
other than it's unboxed type will fail if an implicit/explicit conversion operator does not
exist for the conversion.
- Note: This may be extended to support basic value-types without using implicit/explicit operators in the future, but general support is impossible without an additional layer of reflection during execution of the lambda which will significantly slow everything down.
- Nested types are supported, but not optimized at the moment.
All of this is subject to change as the API is tweaked and improved.
