RETURN TYPEOwned native handle

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods.

A native custom operation supporting matrix, scalar, typed array and opaque ports. Prefer cv.gapi.op for exact tuple inference.

Constructors and members

static new

Create an owned GTypedOperation object. Release native handles with using or delete().

new(id: EmbindString, inputs: readonly GraphPortType[], outputs: readonly GraphPortType[], outMeta: GraphTypedMetadataFunction | undefined): GTypedOperation;

id

id argument (EmbindString).

inputs

inputs argument (readonly GraphPortType[]).

outputs

outputs argument (readonly GraphPortType[]).

outMeta

out meta argument (GraphTypedMetadataFunction | undefined).

Returns

The GTypedOperation result. Release returned native handles with using or delete(), including handles nested in results.

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

on

Connect input graph nodes in signature order and return the declared output nodes. Incorrect node kinds or counts throw.

on(inputs: readonly GraphNode[]): GraphNode[];

inputs

inputs argument (readonly GraphNode[]).

Returns

The GraphNode[] result. Release returned native handles with using or delete(), including handles nested in results.

kernel

Create a synchronous CPU kernel. Assign scalar, array and opaque output slots and fill matrix outputs. Matrix and drawing-primitive handles passed to the callback are borrowed until return.

kernel(run: GraphTypedKernelFunction): GKernelPackage;

run

run argument (GraphTypedKernelFunction).

Returns

The GKernelPackage result. Release returned native handles with using or delete(), including handles nested in results.

These signatures describe this package. Upstream documentation can mention optional backends that are absent from this build. Check runtime compatibility before choosing a backend or file format.
