    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

 , 
  
  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

 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.

 * 
 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.

    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

 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.

 * 
 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.
