=head1 Name
SPVM::Document::NativeAPI::Runtime - Runtime Native APIs
=head1 Description
The runtime native APIs of L<SPVM> are the APIs for SPVM runtimes.
=head1 Usage
  SPVM_API_RUNTIME* api_runtime = env->api->runtime;
   
  int32_t basic_types_length = api_runtime->get_basic_types_length(env->runtime);
=head1 Runtime Native APIs
=head2 get_object_data_offset
C<int32_t (*get_object_data_offset)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns the offset of data area in L<SPVM_OBJECT|SPVM::Document::NativeAPI/"SPVM_OBJECT"> struct.
Elements in an array or fields or a pointer in a pointer class is stored into the data area.
=head2 get_object_ref_count_offset
C<int32_t (*get_object_ref_count_offset)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns the offset of the C<ref_count> field in L<SPVM_OBJECT|SPVM::Document::NativeAPI/"SPVM_OBJECT"> struct.
=head2 get_object_length_offset
C<int32_t (*get_object_length_offset)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns the offset of the C<length> field in L<SPVM_OBJECT|SPVM::Document::NativeAPI/"SPVM_OBJECT"> struct.
=head2 get_basic_type_by_id
C<void* (*get_basic_type_by_id)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>, int32_t basic_type_id);>
Searches a L<basic type|SPVM::Document::NativeAPI::BasicType> given the basic type ID I<basic_type_id>.
If it is found, returns it. Otherwise, returns C<NULL>.
=head2 get_basic_type_by_name
C<void* (*get_basic_type_by_name)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>, const char* basic_type_name);>
Searches a L<basic type|SPVM::Document::NativeAPI::BasicType> given the basic type name I<basic_type_name>.
If it is found, returns it. Otherwise, returns C<NULL>.
=head2 get_basic_types_length
C<int32_t (*get_basic_types_length)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns the length of the basic types owned by the SPVM runtime I<runtime>.
=head2 build_precompile_class_source
C<void (*build_precompile_class_source)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>, L<void* string_buffer|SPVM::Document::NativeAPI::StringBuffer>, L<void* basic_type|SPVM::Document::NativeAPI::BasicType>);>
Creates a C source code for methods with the C<precompile> attribute defined in the class given by the its basic type I<basic_type>, and saves it to the string buffer I<string_buffer>.
=head2 build_precompile_method_source
C<void (*build_precompile_method_source)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>, L<void* string_buffer|SPVM::Document::NativeAPI::StringBuffer>, L<void* method|SPVM::Document::NativeAPI::Method>);>
Creates a C source code for the method I<method>, and saves it to the string buffer I<string_buffer>.
=head2 get_compiler
C<void* (*get_compiler)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns the value of the C<compiler> field. The compiler that build the runtime I<runtime> is stored to this field.
=head2 set_compiler
C<void (*set_compiler)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>, L<void* compiler|SPVM::Document::NativeAPI::Compiler>);>
Sets I<compiler> to the C<compiler> field.
=head2 get_spvm_stdin
C<FILE* (*get_spvm_stdin)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns L<SPVM's standard input|SPVM::Document::Language::System/"Standard Streams">.
=head2 get_spvm_stdout
C<FILE* (*get_spvm_stdout)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns L<SPVM's standard output|SPVM::Document::Language::System/"Standard Streams">.
=head2 get_spvm_stderr
C<FILE* (*get_spvm_stderr)(L<void* runtime|SPVM::Document::NativeAPI::Runtime>);>
Returns L<SPVM's standard error|SPVM::Document::Language::System/"Standard Streams">.
