Name

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

Description

The runtime native APIs of SPVM are the APIs for SPVM runtimes.

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 data area in SPVM_OBJECT struct.

Elements in an array or fields or a pointer in a pointer class is stored into the data area.

get_object_ref_count_offset

int32_t (*get_object_ref_count_offset)(void* runtime);

Returns the offset of the ref_count field in SPVM_OBJECT struct.

get_object_length_offset

int32_t (*get_object_length_offset)(void* runtime);

Returns the offset of the length field in SPVM_OBJECT struct.

get_basic_type_by_id

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

Searches a basic type given the basic type ID basic_type_id.

If it is found, returns it. Otherwise, returns NULL.

get_basic_type_by_name

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

Searches a basic type given the basic type name basic_type_name.

If it is found, returns it. Otherwise, returns NULL.

get_basic_types_length

int32_t (*get_basic_types_length)(void* runtime);

Returns the length of the basic types owned by the SPVM runtime runtime.

build_precompile_class_source

void (*build_precompile_class_source)(void* runtime, void* string_buffer, void* basic_type);

Creates a C source code for methods with the precompile attribute defined in the class given by the its basic type basic_type, and saves it to the string buffer string_buffer.

build_precompile_method_source

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

Creates a C source code for the method method, and saves it to the string buffer string_buffer.

get_compiler

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

Returns the value of the compiler field. The compiler that build the runtime runtime is stored to this field.

set_compiler

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

Sets compiler to the compiler field.

get_spvm_stdin

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

Returns SPVM's standard input.

get_spvm_stdout

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

Returns SPVM's standard output.

get_spvm_stderr

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

Returns SPVM's standard error.
