SPVM::Document::NativeAPI::Method - Method Native APIs

Description

The method native APIs in SPVM are the APIs to get definition information for methods.

Usage

SPVM_API_METHOD* api_method = env->api->method;

void* basic_type = env->get_basic_type(env, stack, "Foo");

void* method = env->api->basic_type->get_method_by_name(env->runtime, basic_type, "get");

const char* method_name = api_method->get_name(env->runtime, method);

Native APIs

get_name

const char* (*get_name)(void* runtime, void* method);

Returns the name of the method method.

get_index

int32_t (*get_index)(void* runtime, void* method);

Returns the index of the method method. This index is the position of the method method in its belonging class.

get_return_basic_type

void* (*get_return_basic_type)(void* runtime, void* method);

Returns the basic type of the return type of the method method.

get_return_type_dimension

int32_t (*get_return_type_dimension)(void* runtime, void* method);

Returns the type dimention of the return type of the method method.

get_return_type_flag

int32_t (*get_return_type_flag)(void* runtime, void* method);

Returns the type flag ID of the return type of the method method.

get_arg_by_index

void* (*get_arg_by_index)(void* runtime, void* method, int32_t arg_index);

Searches a argument at the index arg_index.

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

get_args_length

int32_t (*get_args_length)(void* runtime, void* method);

Returns the length of the arguments of the method method.

get_required_args_length

int32_t (*get_required_args_length)(void* runtime, void* method);

Returns the length of the required arguments of the method method.

get_current_basic_type

void* (*get_current_basic_type)(void* runtime, void* method);

Returns the basic type that owns the method method.

get_opcode_by_index

void* (*get_opcode_by_index)(void* runtime, void* method, int32_t opcode_index);

Searches an operation code at the index opcode_index.

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

get_opcodes_length

int32_t (*get_opcodes_length)(void* runtime, void* method);

Returns the length of operation codes.

is_class_method

int32_t (*is_class_method)(void* runtime, void* method);

If the method method is a class method, returns 1, otherwise returns 0.

is_anon

int32_t (*is_anon)(void* runtime, void* method);

If the method method is an anon method, returns 1, otherwise returns 0.

is_native

int32_t (*is_native)(void* runtime, void* method);

If the method method is a native method, returns 1, otherwise returns 0.

is_precompile

int32_t (*is_precompile)(void* runtime, void* method);

If the method method is a method with the precompile attribute, returns 1, otherwise returns 0.

is_enum

int32_t (*is_enum)(void* runtime, void* method);

If the method method is an enumeration, returns 1, otherwise returns 0.

get_byte_vars_width

int32_t (*get_byte_vars_width)(void* runtime, void* method);

Returns the length of the variables of the byte type allocated by the method method.

get_short_vars_width

int32_t (*get_short_vars_width)(void* runtime, void* method);

Returns the length of the variables of the short type allocated by the method method.

get_int_vars_width

int32_t (*get_int_vars_width)(void* runtime, void* method);

Returns the length of the variables of the int type allocated by the method method.

get_long_vars_width

int32_t (*get_long_vars_width)(void* runtime, void* method);

Returns the length of the variables of the long type allocated by the method method.

get_float_vars_width

int32_t (*get_float_vars_width)(void* runtime, void* method);

Returns the length of the variables of the float type allocated by the method method.

get_double_vars_width

int32_t (*get_double_vars_width)(void* runtime, void* method);

Returns the length of the variables of the double type allocated by the method method.

get_object_vars_width

int32_t (*get_object_vars_width)(void* runtime, void* method);

Returns the length of the variables of the object type allocated by the method method.

get_ref_vars_width

int32_t (*get_ref_vars_width)(void* runtime, void* method);

Returns the length of the variables of the reference type allocated by the method method.

get_mortal_stack_length

int32_t (*get_mortal_stack_length)(void* runtime, void* method);

Returns the length of the mortal stack of the method method.

get_native_address

void* (*get_native_address)(void* runtime, void* method);

Returns the native_address field of the method method. The address of the machine code for a native method is stored to this field.

set_native_address

void (*set_native_address)(void* runtime, void* method, void* address);

Sets address to the native_address field of the method method.

get_precompile_address

void* (*get_precompile_address)(void* runtime, void* method);

Returns the precompile_address field of the method method. The address of the machine code for a precompiled method is stored to this field.

set_precompile_address

void (*set_precompile_address)(void* runtime, void* method, void* address);

Sets address to the precompile_address field of the method method.

is_precompile_fallback

int32_t (*is_precompile_fallback)(void* runtime, void* method);

Gets the is_precompile_fallback field.

If this field is a true value, the precompilation method that does not have the execution address is fallback to the vm method.

void (*set_is_precompile_fallback)(void* runtime, void* method, int32_t is_precompile_fallback);

Sets the is_precompile_fallback field to is_precompile_fallback.
