Public static functions
BuildFromAllocation
std::unique_ptr< FlatBufferModel > BuildFromAllocation( std::unique_ptr< Allocation > allocation, ErrorReporter *error_reporter )
Builds a model directly from an allocation.
Ownership of the allocation is passed to the model, but the caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure (e.g., the allocation is invalid).
BuildFromBuffer
std::unique_ptr< FlatBufferModel > BuildFromBuffer( const char *caller_owned_buffer, size_t buffer_size, ErrorReporter *error_reporter )
Builds a model based on a pre-loaded flatbuffer.
Caller retains ownership of the buffer and should keep it alive until the returned object is destroyed. Caller also retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure. NOTE: this does NOT validate the buffer so it should NOT be called on invalid/untrusted input. Use VerifyAndBuildFromBuffer in that case
BuildFromFile
std::unique_ptr< FlatBufferModel > BuildFromFile( const char *filename, ErrorReporter *error_reporter )
Builds a model based on a file.
Caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure.
BuildFromModel
std::unique_ptr< FlatBufferModel > BuildFromModel( const tflite::Model *caller_owned_model_spec, ErrorReporter *error_reporter )
Builds a model directly from a flatbuffer pointer Caller retains ownership of the buffer and should keep it alive until the returned object is destroyed.
Caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure.
ByteConvertModel
std::unique_ptr< FlatBufferModel > ByteConvertModel( std::unique_ptr< FlatBufferModel > model, ErrorReporter *error_reporter, bool from_big_endian )
Convert the TFLite buffers field between LE and BE format in a FlatBufferModel which is not empty and return the converted instance.
ByteSwapBuffer
void ByteSwapBuffer( int8_t tensor_type, size_t buffer_size, uint8_t *buffer, bool from_big_endian )
Byte swap a constant buffer in place.
ByteSwapFlatBufferModel
std::unique_ptr< FlatBufferModel > ByteSwapFlatBufferModel( std::unique_ptr< FlatBufferModel > model, ErrorReporter *error_reporter, bool from_big_endian )
Byte Swap the TFLite buffers field in a FlatBufferModel and return the swapped instance.
ByteSwapSerializedModel
void ByteSwapSerializedModel( std::string *serialized_model, bool from_big_endian )
Byte Swap the serialized String of a TFLite model in place.
ByteSwapTFLiteModel
void ByteSwapTFLiteModel( const tflite::Model *tfl_model, bool from_big_endian )
Byte swap the buffers field of a TFLite Model instance in place.
ByteSwapTFLiteModelT
void ByteSwapTFLiteModelT( tflite::ModelT *tfl_modelt, bool from_big_endian )
Byte swap the buffers field of a TFLite ModelT instance in place.
CheckBufferOutsideModel
bool CheckBufferOutsideModel( const tflite::Model *model )
ReadAllMetadata
std::map< std::string, std::string > ReadAllMetadata( const ::tflite::Model *model )
VerifyAndBuildFromAllocation
std::unique_ptr< FlatBufferModel > VerifyAndBuildFromAllocation( std::unique_ptr< Allocation > allocation, TfLiteVerifier *extra_verifier, ErrorReporter *error_reporter )
Verifies whether the content of the allocation is legit, then builds a model based on the provided allocation.
The extra_verifier argument is an additional optional verifier for the buffer. By default, we always check with tflite::VerifyModelBuffer. If extra_verifier is supplied, the buffer is checked against the extra_verifier after the check against tflite::VerifyModelBuilder. Ownership of the allocation is passed to the model, but the caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure.
VerifyAndBuildFromBuffer
std::unique_ptr< FlatBufferModel > VerifyAndBuildFromBuffer( const char *caller_owned_buffer, size_t buffer_size, TfLiteVerifier *extra_verifier, ErrorReporter *error_reporter )
Verifies whether the content of the buffer is legit, then builds a model based on the pre-loaded flatbuffer.
The extra_verifier argument is an additional optional verifier for the buffer. By default, we always check with tflite::VerifyModelBuffer. If extra_verifier is supplied, the buffer is checked against the extra_verifier after the check against tflite::VerifyModelBuilder. The caller retains ownership of the buffer and should keep it alive until the returned object is destroyed. Caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure.
VerifyAndBuildFromFile
std::unique_ptr< FlatBufferModel > VerifyAndBuildFromFile( const char *filename, TfLiteVerifier *extra_verifier, ErrorReporter *error_reporter )
Verifies whether the content of the file is legit, then builds a model based on the file.
The extra_verifier argument is an additional optional verifier for the file contents. By default, we always check with tflite::VerifyModelBuffer. If extra_verifier is supplied, the file contents is also checked against the extra_verifier after the check against tflite::VerifyModelBuilder. Caller retains ownership of error_reporter
and must ensure its lifetime is longer than the FlatBufferModel instance. Returns a nullptr in case of failure.
