    • TargetType

      public TargetType(com.sun.tools.javac.code.Type type, TreePath path)
      Creates an instance of a TargetType record class.
      Parameters:
      type - the value for the type record component
      path - the value for the path record component

  • Method Details

    • targetType

      public static @Nullable TargetType targetType(VisitorState state)
      Returns the target type of the tree at the given VisitorState's path, or else null.

      For example, the target type of an assignment expression is the variable's type, and the target type of a return statement is the enclosing method's type.

      A general mental model is that the target type of an expression where the value is used is the highest supertype that you could cast to and still have this compile.

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • type

      public com.sun.tools.javac.code.Type type()
      Returns the value of the type record component.
      Returns:
      the value of the type record component

    • path

      public TreePath path()
      Returns the value of the path record component.
      Returns:
      the value of the path record component
