SPVM::Document::NativeAPI::Runtime - Runtime Native APIs

Description

The runtime native APIs of SPVM are the APIs to manipulate information of runtime.

Usage

  SPVM_API_RUNTIME* api_runtime = env->api->runtime;
  
  int32_t basic_types_length = api_runtime->get_basic_types_length(env->runtime);

Runtime Native APIs

get_object_data_offset

  int32_t (*get_object_data_offset)(void* runtime);

Returns the offset of the data of the SPVM_OBJECT type.

The runtime argument is a runtime object.

get_object_ref_count_offset

  int32_t (*get_object_ref_count_offset)(void* runtime);

Returns the offset of the ref_count member variable of the SPVM_OBJECT type.

The runtime argument is a runtime object.

get_object_length_offset

  int32_t (*get_object_length_offset)(void* runtime);

Returns the offset of the length member variable of the SPVM_OBJECT type.

The runtime argument is a runtime object.

get_basic_type_by_id

  void* (*get_basic_type_by_id)(void* runtime, int32_t basic_type_id);

Gets a basic type object by a basic type ID and returns it.

The runtime argument is a runtime object.

get_basic_type_by_name

  void* (*get_basic_type_by_name)(void* runtime, const char* basic_type_name);

Gets a basic type object by a basic type name and returns it.

The runtime argument is a runtime object.

get_basic_types_length

  int32_t (*get_basic_types_length)(void* runtime);

Gets the length of the basic types.

The runtime argument is a runtime object.

build_precompile_module_source

  void (*build_precompile_module_source)(void* runtime, void* string_buffer, void* module_basic_type);

Builds the C source code of a precompiled module, and saves it to the string buffer.

The runtime argument is a runtime object.

The string_buffer argument is a string buffer object.

The module_basic_type argument is a basic type object.

build_precompile_method_source

  void (*build_precompile_method_source)(void* runtime, void* string_buffer, void* method);
  

Builds the C source code of a precompiled method, and saves it to the string buffer.

The runtime argument is a runtime object.

The string_buffer argument is a string buffer object.

The method argument is a method object.

get_compiler

  void* (*get_compiler)(void* runtime);

set_compiler

  void (*set_compiler)(void* runtime, void* compiler);

get_spvm_stdin

  FILE* (*get_spvm_stdin)(void* runtime);

get_spvm_stdout

  FILE* (*get_spvm_stdout)(void* runtime);

get_spvm_stderr

  FILE* (*get_spvm_stderr)(void* runtime);
