摘要:
An operation (such as a relational query) may be processed on a processing engine (such as a relational database server) on behalf of a client. A conventional processing involves the delivery of the operation to the processing engine, which executes the entire operation to completion and returns a result data set. It may be more efficient to allocate part of the operation to be performed on the client, but a developer may be unable or unavailable to rewrite the operation in a distributed manner. Instead, the operation may be automatically partitioned into a pre-engine client portion, a processing engine portion, and a client portion, and the instructions of each portion may be automatically allocated respectively to the client, the server, and the client. The partitioning may be adjusted to conserve computing resources, such as bandwidth and storage, and the instructions may be reordered to improve the processing of the operation.

Object instance annotation technology is disclosed. This technology is capable of annotating any number of instances for any number of objects. Object instance annotations can be of various types, and annotations can serve as data extensions. Objects are enabled for annotation either by developers, or, alternatively, automatically by a programming language or framework. Furthermore, an interface is provided for annotations. This interface has a variety of operations, some of which allow for adding, retrieving, or removing annotations. Annotations can be reference types or even value types. They may also be private class types. Once object instances are enabled for annotating, and the interface is set up, this interface can annotate a multitude of different kinds of objects. For example, it can annotate generic objects, XML trees, CodeDom trees, and so on.

Memory efficient data processing is provided in a computer environment. A data representation or description is utilized to reduce memory footprint. A data structure can be serialized iteratively utilizing the representation rather than first loading the entire data structure to memory. Portions of the data structure can be materialized to and removed from memory as function of operational need.

Partial methods enable separation of method declaration and/or calls from method implementation. A partial method specifies a signature of a join or hook point in a class. Calls to a partial method specify a join or hook point in code that can optionally be linked with an actual method implementation of the same signature. Separate method implementations or other code related to a partial method are injected into a single program prior to execution. Unimplemented partial methods are treated as no operation instructions or otherwise ignored.

A system and methods for versioning software components in connection with a computer programming language are provided. In exemplary aspects, the versioning system makes use of intelligent defaults, provides a vehicle for unambiguous specification of developer intent and implements conflict resolution rules in connection with the versioning of software components. In another aspect, the versioning system bounds names at run-time, but does not bound offsets at compile-time.

Systems and methods facilitate type inference in a computer-programming environment. Type inference can be applied to generic method or function invocation in object-oriented languages to determine a type argument list left implicit by a programmer. One or more type arguments can be identified as a parameter type to which all other types in a set of associated parameter types can be converted.

An object reference is tagged with an isolation permission modifier. At least two permissions can be included, and in an example three permissions are included. In implementing the permissions, type modifiers for controlling access to type members through references pointing at an object are defined. One of the type modifiers is associated with each occurrence of a type name. Each of the of type modifiers defines a different access permission to restrict operations on the object to which the reference points.
摘要:
The subject disclosure pertains to interaction with one or more collections of data. Queries and domains are presented as separate entities. A number of compositional operators are provided to manipulate a generic collection of data at a low level. Query comprehensions can specify interactions with one or more collections at a higher or more intuitive level. The query comprehensions can be translated or mapped to operators that can be employed to interact with one or more data collections and return results where applicable.

An application program interface (API) provides a set of functions, including a set of base classes and types that are used in substantially all applications accessing the API, for application developers who build Web applications on Microsoft Corporation's .NET™ platform.
