Method Detail

typedesc2ClassName

public static java.lang.String typedesc2ClassName(java.lang.String desc)

Converts bytecode-like description to java class name that can be loaded with a classloader. Uses less-known feature of class loaders for loading array classes. For base types returns the one-letter string that can be used with loadBaseTypeClass(String).

typedescToSignature(String, jodd.mutable.MutableInteger)

typeref2Name

public static java.lang.String typeref2Name(java.lang.String desc)

Converts type reference to java-name.

loadBaseTypeClass

public static java.lang.Class loadBaseTypeClass(java.lang.String desc)
                                         throws java.lang.ClassNotFoundException

Loads base class type.

Throws:

java.lang.ClassNotFoundException

typedescToSignature

public static java.lang.String typedescToSignature(java.lang.String desc)

Returns java-like signature of a bytecode-like description.

typedescToSignature(String, jodd.mutable.MutableInteger)

typedescToSignature

public static java.lang.String typedescToSignature(java.lang.String desc,
                                                   jodd.mutable.MutableInteger from)

Returns java-like signature of a bytecode-like description. Only first description is parsed. The field signature represents the value of an argument to a function or the value of a variable. It is a series of bytes generated by the following grammar:

  ::= 
       ::= ||
        ::= B|C|D|F|I|J|S|Z
      ::= L;
       ::= [

 The meaning of the base types is as follows:
 B byte signed byte
 C char character
 D double double precision IEEE float
 F float single precision IEEE float
 I int integer
 J long long integer
 L; ... an object of the given class
 S short signed short
 Z boolean true or false
 [ ... array
 

This method converts this string into a Java type declaration such as String[].
