Function Usage

Obtains a resource context object based on a resource key.

Prototype

ResourceContext *GetResourceContext(const ge::AscendString &key)

Parameters

Parameter	Input/Output	Description
key	Input	Unique resource key, which is specified by the InferShape function of the resource operator.

Returns

Resource context object.

The basic definition is as follows, based on which the resource operator can be extended.

struct ResourceContext {  virtual ~ResourceContext() {}};

Used to store resource information, such as shape and data type.

Constraints

Check that the return is not a null pointer before using it, as this API will return a null pointer if the pointer to the resource context manager is not passed when creating InferenceContext using the Create API.
