Noop

object Noop : LensesComponent.Processor

Convenience implementation of Processor which does nothing but notify operation callbacks with failure.

Functions

open fun apply(lens: LensesComponent.Lens, callback: Consumer<Boolean> = Consumer {})

Attempts to apply the provided lens model with Lens.LaunchData.Empty. The operation is async with the result provided as success or failure flag to the callback.

open fun apply(lens: LensesComponent.Lens, launchData: LensesComponent.Lens.LaunchData = Lens.LaunchData.Empty, callback: Consumer<Boolean> = Consumer {})

Attempts to apply the provided lens model with launchData. The operation is async with the result provided as success or failure flag to the callback.

open override fun apply(lens: LensesComponent.Lens, launchData: LensesComponent.Lens.LaunchData, reset: Boolean, callback: Consumer<Boolean>)

Attempts to apply the provided lens model with launchData and the reset flag which determines whether lens state should be reset if the same lens is currently applied. The operation is async with the result provided as success or failure flag to the callback.

open override fun clear(callback: Consumer<Boolean>)

Removes any applied Lens models. The result of the async operation is success if any Lens was removed or failure when there were no lenses to be removed or operation failed to execute.

open override fun connectInput(input: MediaProcessor.Input): Closeable
open override fun connectInput(input: SafeRenderAreaProcessor.Input): Closeable
open override fun connectInput(input: UserProcessor.Input): Closeable

Connects the provided input to this processor and returns a Closeable to release the connection when required. Normally, processing of the provided input starts instantly however certain processors may do it async so it is not guaranteed that any work will be done as soon as input is connected.

@CheckResult
open fun connectInput(input: ImageProcessor.Input, options: Set<ImageProcessor.Input.Option>): Closeable

Connects the provided input to this processor and returns a Closeable to release the connection when required. Normally, processing of the provided input starts instantly however certain processors may do it async so it is not guaranteed that any work will be done as soon as input is connected.

open override fun connectOutput(output: ImageProcessor.Output): Closeable

Connects the provided output to this processor and returns a Closeable to release the connection when required. Similarly to connectInput, it is not guaranteed that the provided output will receive results as soon as it is connected, the processor may do it async.

@CheckResult
open fun connectOutput(output: ImageProcessor.Output, options: Set<ImageProcessor.Output.Option>): Closeable

Connects the provided output to this processor and returns a Closeable to release the connection when required. Similarly to connectInput, it is not guaranteed that the provided output will receive results as soon as it is connected, the processor may do it async.

open override fun observe(onEvent: Consumer<LensesComponent.Processor.Event>): Closeable

Allows to observe lens lifecycle events defined in Event.

open override fun observeRequiredCapabilities(onCapabilitiesRequested: Consumer<Set<ImageProcessor.Input.Capability>>): Closeable

Takes in onCapabilitiesRequested that will be notified when image processing operations require additional data from connected Input. Right after observeRequiredCapabilities is called onCapabilitiesRequested consumer will be invoked on the caller thread with the current set of required capabilities. emptySet is used to represent that additional capabilities aren't required.
