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.

See Also:

typedescToSignature(String, jodd.mutable.MutableInteger)

typeref2Name

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

Converts type reference to java-name.

typeNameToOpcode

public static char typeNameToOpcode(java.lang.String typeName)

Returns type-name to type char. Arrays are not supported.

typedescToSignature

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

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

See Also:

typedescToSignature(String, jodd.mutable.MutableInteger)

typedescToSignature

public static java.lang.String typedescToSignature(java.lang.String desc,
                                                   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:

 <field_signature> ::= <field_type>
 <field_type>      ::= <base_type>|<object_type>|<array_type>
 <base_type>       ::= B|C|D|F|I|J|S|Z
 <object_type>     ::= L<fullclassname>;
 <array_type>      ::= [<field_type>

 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<fullclassname>; ... an object of the given class
 S short signed short
 Z boolean true or false
 [<field sig> ... array
 

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