public final class Signature extends Object

Provides methods for encoding and decoding type and method signature strings.

Signatures obtained from parsing source files (i.e. files with one of the Java-like extensions) differ subtly from ones obtained from pre-compiled binary (".class") files in class names are usually left unresolved in the former. For example, the normal resolved form of the type "String" embeds the class's package name ("Ljava.lang.String;" or "Ljava/lang/String;"), whereas the unresolved form contains only what is written "QString;".

Generic types introduce to the Java language in J2SE 1.5 add three new facets to signatures: type variables, parameterized types with type arguments, and formal type parameters. Rich signatures containing these facets only occur when dealing with code that makes overt use of the new language features. All other code, and certainly all Java code written or compiled with J2SE 1.4 or earlier, involved only simple signatures.

Note that the "Q", "!", "|" and "Ungültige Eingabe: "&"" formats are specific to Eclipse; the remainder are specified in the JVM spec.

Due to historical reasons Eclipse uses "|" format for Intersection and "Ungültige Eingabe: "&"" for Union which is opposite to their usage in source code.

The syntax for a type signature is:

 TypeSignature ::=
     "B"  // byte
   | "C"  // char
   | "D"  // double
   | "F"  // float
   | "I"  // int
   | "J"  // long
   | "S"  // short
   | "V"  // void
   | "Z"  // boolean
   | "T" + Identifier + ";" // type variable
   | "[" + TypeSignature  // array X[]
   | "!" + TypeSignature  // capture-of ?
   | "|" + TypeSignature + (":" + TypeSignature)+ // intersection type
   | ResolvedClassTypeSignature
   | UnresolvedClassTypeSignature

 ResolvedClassTypeSignature ::= // resolved named type (in compiled code)
     "L" + Identifier + OptionalTypeArguments
           ( ( "." | "/" ) + Identifier + OptionalTypeArguments )* + ";"
     | OptionalTypeParameters + "L" + Identifier +
           ( ( "." | "/" ) + Identifier )* + ";"

 UnresolvedClassTypeSignature ::= // unresolved named type (in source code)
     "Q" + Identifier + OptionalTypeArguments
           ( ( "." | "/" ) + Identifier + OptionalTypeArguments )* + ";"
     | OptionalTypeParameters "Q" + Identifier +
           ( ( "." | "/" ) + Identifier )* + ";"

 OptionalTypeArguments ::=
     "<" + TypeArgument+ + ">"
   |

 TypeArgument ::=
   | TypeSignature
   | "*" // wildcard ?
   | "+" TypeSignature // wildcard ? extends X
   | "-" TypeSignature // wildcard ? super X

 OptionalTypeParameters ::=
     "<" + FormalTypeParameterSignature+ + ">"
   |

Examples:

"[[I" denotes int[][]
"Ljava.lang.String;" denotes java.lang.String in compiled code
"QString;" denotes String in source code
"Qjava.lang.String;" denotes java.lang.String in source code
"[QString;" denotes String[] in source code
"QMap<QString;*>;" denotes Map<String,?> in source code
"Qjava.util.List<V>;" denotes java.util.List<V> in source code
"<E>Ljava.util.List;" denotes <E>java.util.List in source code

The syntax for a method signature is:

 MethodSignature ::= OptionalTypeParameters + "(" + ParamTypeSignature* + ")" + ReturnTypeSignature
 ParamTypeSignature ::= TypeSignature
 ReturnTypeSignature ::= TypeSignature

Examples:

"()I" denotes int foo()
"([Ljava.lang.String;)V" denotes void foo(java.lang.String[]) in compiled code
"(QString;)QObject;" denotes Object foo(String) in source code

The syntax for a formal type parameter signature is:

 FormalTypeParameterSignature ::=
     TypeVariableName + OptionalClassBound + InterfaceBound*
 TypeVariableName ::= Identifier
 OptionalClassBound ::=
     ":"
   | ":" + TypeSignature
 InterfaceBound ::=
     ":" + TypeSignature

Examples:

"X:" denotes X
"X:QReader;" denotes X extends Reader in source code
"X:QReader;:QSerializable;" denotes X extends Reader Ungültige Eingabe: "&" Serializable in source code

This class provides static methods and constants only.

Note: An empty signature is considered to be syntactically incorrect. So most methods will throw an IllegalArgumentException if an empty signature is provided.

- createCharArrayTypeSignature
  
  public static char[] createCharArrayTypeSignature(char[] typeName, boolean isResolved)
  
  Creates a new type signature from the given type name encoded as a character array. The type name may contain primitive types or array types or parameterized types or represent an intersection type in source code notation using &. This method is equivalent to createTypeSignature(new String(typeName),isResolved).toCharArray(), although more efficient for callers with character arrays rather than strings. If the type name is qualified, then it is expected to be dot-based.
  Parameter:
  
  typeName - the possibly qualified type name
  
  isResolved - true if the type name is to be considered resolved (for example, a type name from a binary class file), and false if the type name is to be considered unresolved (for example, a type name found in source code)

  public static String createTypeSignature(char[] typeName, boolean isResolved)
  
  Creates a new type signature from the given type name encoded as a character array. The type name may contain primitive types, array types or parameterized types. This method is equivalent to createTypeSignature(new String(typeName),isResolved), although more efficient for callers with character arrays rather than strings. If the type name is qualified, then it is expected to be dot-based.
  Parameter:
  
  typeName - the possibly qualified type name
  
  isResolved - true if the type name is to be considered resolved (for example, a type name from a binary class file), and false if the type name is to be considered unresolved (for example, a type name found in source code)

  public static char[] toCharArray(char[] methodSignature, char[] methodName, char[][] parameterNames, boolean fullyQualifyTypeNames, boolean includeReturnType)
  Converts the given method signature to a readable form. The method signature is expected to be dot-based.
  For example:
  toString("([Ljava.lang.String;)V", "main", new String[] {"args"}, false, true) -> "void main(String[] args)"
  Parameter:
  
  methodSignature - the method signature to convert
  
  methodName - the name of the method to insert in the result, or null if no method name is to be included
  
  parameterNames - the parameter names to insert in the result, or null if no parameter names are to be included; if supplied, the number of parameter names must match that of the method signature
  
  fullyQualifyTypeNames - true if type names should be fully qualified, and false to use only simple names
  
  includeReturnType - true if the return type is to be included
  
  Gibt zurück:

- toQualifiedName
  
  public static char[] toQualifiedName(char[][] segments)
  Converts the given array of qualified name segments to a qualified name.
  For example:
  toQualifiedName({{'j', 'a', 'v', 'a'}, {'l', 'a', 'n', 'g'}, {'O', 'b', 'j', 'e', 'c', 't'}}) -> {'j', 'a', 'v', 'a', '.', 'l', 'a', 'n', 'g', '.', 'O', 'b', 'j', 'e', 'c', 't'} toQualifiedName({{'O', 'b', 'j', 'e', 'c', 't'}}) -> {'O', 'b', 'j', 'e', 'c', 't'} toQualifiedName({{}}) -> {}
  Parameter:
  
  segments - the list of name segments, possibly empty
  
  Gibt zurück:
  
  the dot-separated qualified name, or the empty string

- toQualifiedName
  
  public static String toQualifiedName(String[] segments)
  Converts the given array of qualified name segments to a qualified name.
  For example:
  toQualifiedName(new String[] {"java", "lang", "Object"}) -> "java.lang.Object" toQualifiedName(new String[] {"Object"}) -> "Object" toQualifiedName(new String[0]) -> ""
  Parameter:
  
  segments - the list of name segments, possibly empty
  
  Gibt zurück:
  
  the dot-separated qualified name, or the empty string
- toString
  
  public static String toString(String signature) throws IllegalArgumentException
  Converts the given type signature to a readable string. The signature is expected to be dot-based.
  For example:
  toString("[Ljava.lang.String;") -> "java.lang.String[]" toString("I") -> "int" toString("+QObject;") -> "? extends Object"
  
  Note: This method assumes that a type signature containing a '$' is an inner type signature. While this is correct in most cases, someone could define a non-inner type name containing a '$'. Handling this correctly in all cases would have required resolving the signature, which generally not feasible.
  Parameter:
  
  signature - the type signature
  
  Gibt zurück:
  
  the string representation of the type
  
  Löst aus:
  
  IllegalArgumentException - if the signature is not syntactically correct
- toString
  
  public static String toString(String methodSignature, String methodName, String[] parameterNames, boolean fullyQualifyTypeNames, boolean includeReturnType)
  
  Converts the given method signature to a readable string. The method signature is expected to be dot-based.
  Parameter:
  
  methodSignature - the method signature to convert
  
  methodName - the name of the method to insert in the result, or null if no method name is to be included
  
  parameterNames - the parameter names to insert in the result, or null if no parameter names are to be included; if supplied, the number of parameter names must match that of the method signature
  
  fullyQualifyTypeNames - true if type names should be fully qualified, and false to use only simple names
  
  includeReturnType - true if the return type is to be included
