Method Detail

• getPackageElement

  PackageElement getPackageElement(CharSequence name)

  Returns a package given its fully qualified name.

  Parameters:

  name - fully qualified package name, or "" for an unnamed package

  Returns:

  the named package, or null if it cannot be found

• getTypeElement

  TypeElement getTypeElement(CharSequence name)

  Returns a type element given its canonical name.

  Parameters:

  name - the canonical name

  Returns:

  the named type element, or null if it cannot be found

• getElementValuesWithDefaults

  Map<? extends ExecutableElement,? extends AnnotationValue> getElementValuesWithDefaults(AnnotationMirror a)

  Returns the values of an annotation's elements, including defaults.

  Parameters:

  a - annotation to examine

  Returns:

  the values of the annotation's elements, including defaults

  See Also:

  AnnotationMirror.getElementValues()

• getDocComment

  String getDocComment(Element e)

  Returns the text of the documentation ("Javadoc") comment of an element.

  A documentation comment of an element is a comment that begins with "/**" , ends with a separate "*/", and immediately precedes the element, ignoring white space. Therefore, a documentation comment contains at least three"*" characters. The text returned for the documentation comment is a processed form of the comment as it appears in source code. The leading "/**" and trailing "*/" are removed. For lines of the comment starting after the initial "/**", leading white space characters are discarded as are any consecutive "*" characters appearing after the white space or starting the line. The processed lines are then concatenated together (including line terminators) and returned.

  Parameters:

  e - the element being examined

  Returns:

  the documentation comment of the element, or null if there is none

  See The Java™ Language Specification:

  3.6 White Space

• isDeprecated

  boolean isDeprecated(Element e)

  Returns true if the element is deprecated, false otherwise.

  Parameters:

  e - the element being examined

  Returns:

  true if the element is deprecated, false otherwise

• getBinaryName

  Name getBinaryName(TypeElement type)

  Returns the binary name of a type element.

  Parameters:

  type - the type element being examined

  Returns:

  the binary name

  See Also:

  TypeElement.getQualifiedName()

  See The Java™ Language Specification:

  13.1 The Form of a Binary

• getPackageOf

  PackageElement getPackageOf(Element type)

  Returns the package of an element. The package of a package is itself.

  Parameters:

  type - the element being examined

  Returns:

  the package of an element

• getAllMembers

  List<? extends Element> getAllMembers(TypeElement type)

  Returns all members of a type element, whether inherited or declared directly. For a class the result also includes its constructors, but not local or anonymous classes.

  Note that elements of certain kinds can be isolated using methods in ElementFilter.

  Parameters:

  type - the type being examined

  Returns:

  all members of the type

  See Also:

  Element.getEnclosedElements()

• getAllAnnotationMirrors

  List<? extends AnnotationMirror> getAllAnnotationMirrors(Element e)

  Returns all annotations of an element, whether inherited or directly present.

  Parameters:

  e - the element being examined

  Returns:

  all annotations of the element

  See Also:

  Element.getAnnotationMirrors()

• hides

  boolean hides(Element hider,
              Element hidden)

  Tests whether one type, method, or field hides another.

  Parameters:

  hider - the first element

  hidden - the second element

  Returns:

  true if and only if the first element hides the second

• overrides

  boolean overrides(ExecutableElement overrider,
                  ExecutableElement overridden,
                  TypeElement type)

  Tests whether one method, as a member of a given type, overrides another method. When a non-abstract method overrides an abstract one, the former is also said to implement the latter.

  In the simplest and most typical usage, the value of the type parameter will simply be the class or interface directly enclosing overrider (the possibly-overriding method). For example, suppose m1 represents the method String.hashCode and m2 represents Object.hashCode. We can then ask whether m1 overrides m2 within the class String (it does):

  assert elements.overrides(m1, m2, elements.getTypeElement("java.lang.String"));

  A more interesting case can be illustrated by the following example in which a method in type A does not override a like-named method in type B:

  class A { public void m() {} }
interface B { void m(); }
  ...
  m1 = ...; // A.m
m2 = ...; // B.m
assert ! elements.overrides(m1, m2, elements.getTypeElement("A"));

  When viewed as a member of a third type C, however, the method in A does override the one in B:

  class C extends A implements B {}
  ...
  assert elements.overrides(m1, m2, elements.getTypeElement("C"));

  Parameters:

  overrider - the first method, possible overrider

  overridden - the second method, possibly being overridden

  type - the type of which the first method is a member

  Returns:

  true if and only if the first method overrides the second

  8.4.8 Inheritance, Overriding, and Hiding, 9.4.1 Inheritance and Overriding

• getConstantExpression

  String getConstantExpression(Object value)

  Returns the text of a constant expression representing a primitive value or a string. The text returned is in a form suitable for representing the value in source code.

  Parameters:

  value - a primitive value or string

  Returns:

  the text of a constant expression

  Throws:

  IllegalArgumentException - if the argument is not a primitive value or string

  See Also:

  VariableElement.getConstantValue()

• printElements

  void printElements(Writer w,
                   Element... elements)

  Prints a representation of the elements to the given writer in the specified order. The main purpose of this method is for diagnostics. The exact format of the output is not specified and is subject to change.

  Parameters:

  w - the writer to print the output to

  elements - the elements to print

• getName

  Name getName(CharSequence cs)

  Return a name with the same sequence of characters as the argument.

  Parameters:

  cs - the character sequence to return as a name
