Function Documentation

◆ get_method_handle_type()

static java_class_typet::method_handle_kindt get_method_handle_type ( method_handle_infot::method_handle_kindt java_handle_kind )

static

Translate the lambda method reference kind in a class file into the kind of handling the method requires.

invokestatic/special translate into direct method calls; invokevirtual/interface translate into virtual dispatch, newinvokespecial translates into a special instantiate-and-construct sequence. The field-manipulation reference kinds appear never to happen in reality and don't have syntax in the Java language.

Definition at line 1892 of file java_bytecode_parser.cpp.

◆ java_bytecode_parse() [1/2]

std::optional<java_bytecode_parse_treet> java_bytecode_parse	(	const std::string &	file,
		const irep_idt &	class_name,
		class message_handlert &	msg,
		bool	skip_instructions = `false`
	)

Attempt to parse a Java class from the given file.

Parameters

file	file to load from
class_name	name of the class to load
msg	handles log messages
skip_instructions	if true, the loaded class's methods will all be empty. Saves time and memory for consumers that only want signature info.

Returns: parse tree, or empty std::optional on failure

Definition at line 1830 of file java_bytecode_parser.cpp.

◆ java_bytecode_parse() [2/2]

std::optional<java_bytecode_parse_treet> java_bytecode_parse	(	std::istream &	stream,
		const irep_idt &	class_name,
		class message_handlert &	msg,
		bool	skip_instructions = `false`
	)

Attempt to parse a Java class from the given stream.
