parseClass	back to summary
public static Class<?> parseClass(String descriptor, ClassLoader loader) Parses and validates a field descriptor string in the `loader` context. Parameters descriptor:String a field descriptor string loader:ClassLoader the class loader in which to look up the types (null means bootstrap class loader) Exceptions IllegalArgumentException: if the descriptor is invalid TypeNotPresentException: if the descriptor is valid, but the class cannot be found by the loader

public static Class<?> parseClass(String descriptor, ClassLoader loader)

Parses and validates a field descriptor string in the loader context.

Parameters

descriptor:String: a field descriptor string
loader:ClassLoader: the class loader in which to look up the types (null means bootstrap class loader)

Exceptions

IllegalArgumentException:: if the descriptor is invalid
TypeNotPresentException:: if the descriptor is valid, but the class cannot be found by the loader

Parameters descriptor:String a method descriptor string loader:ClassLoader the class loader in which to look up the types (null means bootstrap class loader) Exceptions IllegalArgumentException: if the descriptor is invalid TypeNotPresentException: if a reference type cannot be found by the loader (before the descriptor is found invalid)

public static List<Class<?>> parseMethod(String descriptor, ClassLoader loader)

Parses and validates a method descriptor string in the loader context.

Parameters

descriptor:String: a method descriptor string
loader:ClassLoader: the class loader in which to look up the types (null means bootstrap class loader)

Exceptions

IllegalArgumentException:: if the descriptor is invalid
TypeNotPresentException:: if a reference type cannot be found by the loader (before the descriptor is found invalid)

parseSig back to summary

parseSig	back to summary
private static Class<?> parseSig(String str, int[] i, int end, ClassLoader loader) Parse a single type in a descriptor. Results can be: A `Class` for successful parsing `null` for malformed descriptor format Throwing a `TypeNotPresentException` for valid class name, but class cannot be found Parameters str:String contains the string to parse i:int[] cursor for the next token in the string, modified in-place end:int the limit for parsing loader:ClassLoader the class loader in which to look up the types (null means bootstrap class loader)

private static Class<?> parseSig(String str, int[] i, int end, ClassLoader loader)

Parse a single type in a descriptor. Results can be:

A Class for successful parsing
null for malformed descriptor format
Throwing a TypeNotPresentException for valid class name, but class cannot be found

Parameters

str:String: contains the string to parse
i:int[]: cursor for the next token in the string, modified in-place
end:int: the limit for parsing
loader:ClassLoader: the class loader in which to look up the types (null means bootstrap class loader)
