tflite::impl::InterpreterBuilder Class Reference

# tflite::impl::InterpreterBuilder

## Summary

Note: `tflite::impl::InterpreterBuilder` class is implementation details. Users should reference it as `tflite::InterpreterBuilder` instead.

### Constructors and Destructors
`InterpreterBuilder(const FlatBufferModel & model, const OpResolver & op_resolver, const InterpreterOptions *options_experimental)` For this constructor, the ErrorReporter will be extracted from the FlatBufferModel.
`InterpreterBuilder(const ::tflite::Model *model, const OpResolver & op_resolver, ErrorReporter *error_reporter, const InterpreterOptions *options_experimental)` Builds an interpreter given only the raw flatbuffer Model object (instead of a FlatBufferModel).
`InterpreterBuilder(const InterpreterBuilder &)`
`~InterpreterBuilder()`

### Public functions
`AddDelegate(TfLiteDelegate *delegate)` | `void` Any delegates added with AddDelegate will be applied to the Interpreter generated by operator(), in the order that they were added.
`AddDelegate(TfLiteOpaqueDelegateStruct *opaque_delegate)` | `void`
`SetNumThreads(int num_threads)` | `TfLiteStatus` Sets the number of CPU threads to use for the interpreter.
`SetTelemetryProfiler(std::unique_ptr< telemetry::TelemetryProfiler > profiler)` | `void`
`operator()(std::unique_ptr< Interpreter > *interpreter)` | `TfLiteStatus` Builds an interpreter and stores it in `*interpreter`.
`operator()(std::unique_ptr< Interpreter > *interpreter, int num_threads)` | `TfLiteStatus` Same as above, but also sets the number of CPU threads to use (overriding any previous call to SetNumThreads).
`operator=(const InterpreterBuilder &)=delete` | `InterpreterBuilder &`

## Public functions

### AddDelegate

    void AddDelegate(
      TfLiteDelegate *delegate
    )

Any delegates added with AddDelegate will be applied to the Interpreter generated by operator(), in the order that they were added.

(The delegate parameter passed to AddDelegate should be non-null, otherwise an error will be reported, and the call to AddDelegate will have no other effect.) The lifetime of the delegate must be at least as long as the lifetime of any Interpreter generated by this InterpreterBuilder.

### AddDelegate

    void AddDelegate(
      TfLiteOpaqueDelegateStruct *opaque_delegate
    )

### InterpreterBuilder

     InterpreterBuilder(
      const FlatBufferModel & model,
      const OpResolver & op_resolver,
      const InterpreterOptions *options_experimental
    )

For this constructor, the ErrorReporter will be extracted from the FlatBufferModel.

`options` object is copied during construction. So caller can release it

### InterpreterBuilder

     InterpreterBuilder(
      const ::tflite::Model *model,
      const OpResolver & op_resolver,
      ErrorReporter *error_reporter,
      const InterpreterOptions *options_experimental
    )

Builds an interpreter given only the raw flatbuffer Model object (instead of a FlatBufferModel).

Mostly used for testing. If `error_reporter` is null, then DefaultErrorReporter() is used. `options` object is copied during construction. So caller can release it

### InterpreterBuilder

     InterpreterBuilder(
      const InterpreterBuilder &
    )=delete

### SetNumThreads

    TfLiteStatus SetNumThreads(
      int num_threads
    )

Sets the number of CPU threads to use for the interpreter.

Returns kTfLiteOk on success, kTfLiteError on error.

### SetTelemetryProfiler

    void SetTelemetryProfiler(
      std::unique_ptr< telemetry::TelemetryProfiler > profiler
    )

### operator()

    TfLiteStatus operator()(
      std::unique_ptr< Interpreter > *interpreter
    )

Builds an interpreter and stores it in `*interpreter`.

On success, returns kTfLiteOk and sets `*interpreter` to a valid Interpreter. On failure, returns an error status and sets `*interpreter` to nullptr.

### operator()

    TfLiteStatus operator()(
      std::unique_ptr< Interpreter > *interpreter,
      int num_threads
    )

Same as above, but also sets the number of CPU threads to use (overriding any previous call to SetNumThreads).

Deprecated: use the SetNumThreads method instead.

### operator=

    InterpreterBuilder & operator=(
      const InterpreterBuilder &
    )=delete

### ~InterpreterBuilder

     ~InterpreterBuilder()
