Detailed Description

Class to hold type with generic type arguments, for example java.util.List in either a reference of type List<Integer> or List<T> (here T must have been concretized already to create this object so technically it is an argument rather than parameter/variable, but in the symbol table this still shows as the parameter T).

The vector holds the types of the type arguments (all of type or subtype of reference_typet), that is the vector has the length of the number of type parameters of the generic class. For example:

in HashMap<K, V> it would contain two elements, each of type java_generic_parametert,
in HashMap<Integer, V> it would contain two elements, the first of type reference_typet and the second of type java_generic_parametert,
in HashMap<List<T>, V> it would contain two elements, the first of type java_generic_typet and the second of type java_generic_parametert.

◆ java_generic_struct_tag_typet() [2/2]

java_generic_struct_tag_typet::java_generic_struct_tag_typet	(	const struct_tag_typet &	type,
		const std::string &	base_ref,
		const std::string &	class_name_prefix )

Construct a generic symbol type by extending the symbol type type with generic types extracted from the reference base_ref.

This assumes that the class named class_name_prefix extends or implements the class type, and that base_ref corresponds to a generic class. For instance since HashMap<K,V> extends Map<K,V> we would call java_generic_struct_tag_typet(struct_tag_typet("Map"), "Ljava/util/Map<TK;TV;>;", "java.util.HashMap") which generates a symbol type with identifier "Map", and two generic types with identifier "java.util.HashMap::K" and "java.util.HashMap::V" respectively.

Member Function Documentation

◆ generic_type_index()

optionalt< size_t > java_generic_struct_tag_typet::generic_type_index ( const java_generic_parametert & type ) const

Check if this symbol has the given generic type.

If yes, return its index in the vector of generic types.

Parameters

type	The parameter type we are looking for.

Returns: The index of the type in the vector of generic types.
