Method Detail

asDottedString

public static String asDottedString(char[][] name)

Returns a source name from an array of names.

join

public static String join(char[][] name,
                          String separator)

Returns a string name from an array of names using separator.

getClassName

public static String getClassName(org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding binding)

Returns the name of the class from reference binding.

JDT Core (at least 3.11.0.v20150407) returns $Local$ synthetic name for local classes.
This method aware about local classes and instead of $Local$ synthetic name returns fully qualified name of the local class in form of anonymous class (e.g. test.Class1$2).

getDefiningCompilationUnitType

public static String getDefiningCompilationUnitType(org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding binding)

Returns the top type of the compilation unit that defines binding.

getSourceName

public static String getSourceName(org.eclipse.jdt.internal.compiler.lookup.TypeBinding classBinding)

getSourceName

public static String getSourceName(String qualifiedPackageName,
                                   String qualifiedSourceName)

getBinaryName

public static String getBinaryName(org.eclipse.jdt.internal.compiler.lookup.TypeBinding classBinding)

getBinaryName

public static String getBinaryName(String qualifiedPackageName,
                                   String qualifiedSourceName)

isInnerClass

public static boolean isInnerClass(org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding binding)

formatMethodSignature

public static String formatMethodSignature(org.eclipse.jdt.internal.compiler.lookup.MethodBinding methodBinding)

Get a readable method description from methodBinding conforming with JSNI formatting.

See examples:

• a constructor of class A with a java.lang.String parameter will be formatted as "new(Ljava/lang/String;).
• a method with name m with an parameter of class java.lang.Object and return type boolean will be formatted as "m(Ljava/lang/Object;
