tflite::MutableOpResolver

#include <mutable_op_resolver.h>

An OpResolver that is mutable, also used as the op in gen_op_registration.

Summary

A typical usage: MutableOpResolver resolver; resolver.AddBuiltin(BuiltinOperator_ADD, Register_ADD()); resolver.AddCustom("CustomOp", Register_CUSTOM_OP()); InterpreterBuilder(model, resolver)(&interpreter);

Protected attributes

delegate_creators_

TfLiteDelegateCreators delegate_creators_

A vector of delegate creators to create optional delegates for resolving and handling ops in the flatbuffer model.

This may be used in addition to the standard TfLiteRegistration lookup for graph resolution.

may_directly_contain_user_defined_ops_

bool may_directly_contain_user_defined_ops_ = false

True if this OpResolver itself (as opposed to chained op resolvers registed with ChainOpResolver) may contain user defined ops.

By "user defined" ops, we mean any op definitions other than those contained in tflite::ops::builtin::BuiltinOpResolver.

opaque_delegate_creators_

TfLiteOpaqueDelegateCreators opaque_delegate_creators_

A vector of opaque delegate creators to create optional opaque delegates for resolving and handling ops in the flatbuffer model.

This may be used in addition to the standard TfLiteRegistration lookup for graph resolution. This is used for TF Lite in Google Play Services.

Public functions

AddAll

void AddAll(
  const MutableOpResolver & other
)

Registers all operator versions supported by another MutableOpResolver.

Replaces any previous registrations for the same operator versions, except that registrations made with AddBuiltin or AddCustom always take precedence over registrations made with ChainOpResolver.

AddBuiltin

void AddBuiltin(
  tflite::BuiltinOperator op,
  const TfLiteRegistration *registration,
  int version
)

Registers the specified version of the specified builtin operator op.

Replaces any previous registration for the same operator version.

AddBuiltin

void AddBuiltin(
  tflite::BuiltinOperator op,
  const TfLiteRegistration *registration,
  int min_version,
  int max_version
)

Registers the specified version range (versions min_version to max_version, inclusive) of the specified builtin operator op.

Replaces any previous registration for the same operator version.

AddCustom

void AddCustom(
  const char *name,
  const TfLiteRegistration *registration,
  int version
)

Registers the specified version of the specified builtin operator op.

Replaces any previous registration for the same operator version.

AddCustom

void AddCustom(
  const char *name,
  const TfLiteRegistration *registration,
  int min_version,
  int max_version
)

Registers the specified version range (versions min_version to max_version, inclusive) of the specified custom operator name.

Replaces any previous registration for the same operator version.

FindOp

virtual const TfLiteRegistration * FindOp(
  tflite::BuiltinOperator op,
  int version
) const override

Finds the op registration for a builtin operator by enum code.

FindOp

virtual const TfLiteRegistration * FindOp(
  const char *op,
  int version
) const override

Finds the op registration of a custom operator by op name.

GetDelegateCreators

GetOpaqueDelegateCreators

virtual OpResolver::TfLiteOpaqueDelegateCreators GetOpaqueDelegateCreators() const final

Protected functions

ChainOpResolver

void ChainOpResolver(
  const OpResolver *other
)

Registers all operator versions supported by another OpResolver, except any already registered in this MutableOpResolver.

other must point to an OpResolver whose lifetime is at least as long as the lifetime of the MutableOpResolver pointed to by this. The OpResolver pointed to by other should not be modified during the lifetime of this MutableOpResolver.
