  public java.lang.Class<?> instanceClass​()
                                   throws java.io.IOException,
                                          java.lang.ClassNotFoundException

• isApplet

  @Deprecated
  public boolean isApplet​()

  Deprecated. This method probably should not be used, as it catches a variety of potentially serious exceptions and errors, and swallows them so as to produce a simple boolean result. (Notifying them all would be inappropriate as they typically come from user code.) Better to directly parse the bytecode, using e.g. the classfile module, which is immune to this class of errors.
  Is this an applet?

  Returns:

  true if this class is a java.applet.Applet

• isExecutable

  @Deprecated
  public boolean isExecutable​()

  Deprecated. This method probably should not be used, as it catches a variety of potentially serious exceptions and errors, and swallows them so as to produce a simple boolean result. (Notifying them all would be inappropriate as they typically come from user code.) Better to directly parse the bytecode, using e.g. the classfile module, which is immune to this class of errors.
  Is this a standalone executable?

  Returns:

  true if this class has main method (e.g., public static void main (String[] arguments)).

• isJavaBean

  @Deprecated
  public boolean isJavaBean​()

  Deprecated. This method probably should not be used, as it catches a variety of potentially serious exceptions and errors, and swallows them so as to produce a simple boolean result. (Notifying them all would be inappropriate as they typically come from user code.) Better to directly parse the bytecode, using e.g. the classfile module, which is immune to this class of errors.
  Is this a JavaBean?

  Returns:

  true if this class represents JavaBean (is public and has a public default constructor).

• isInterface

  @Deprecated
  public boolean isInterface​()

  Deprecated. This method probably should not be used, as it catches a variety of potentially serious exceptions and errors, and swallows them so as to produce a simple boolean result. (Notifying them all would be inappropriate as they typically come from user code.) Better to directly parse the bytecode, using e.g. the classfile module, which is immune to this class of errors.
  Is this an interface?

  Returns:

  true if the class is an interface

• toString

  public java.lang.String toString​()

  Overrides:

  toString in class java.lang.Object

• findHelp

  @Deprecated
  public static org.openide.util.HelpCtx findHelp​(org.openide.cookies.InstanceCookie instance)

  Deprecated. use org.openide.util.HelpCtx.findHelp (Object)
  Find context help for some instance. Helper method useful in nodes or data objects that provide an instance cookie; they may choose to supply their own help context based on this. All API classes which can provide help contexts will be tested for (including HelpCtx instances themselves). JComponents are checked for an attached help ID property, as with HelpCtx.findHelp(java.awt.Component) (but not traversing parents).

  Also, partial compliance with the JavaHelp section on JavaBeans help is implemented--i.e., if a Bean in its BeanInfo provides a BeanDescriptor which has the attribute helpID, this will be returned. The value is not defaulted (because it would usually be nonsense and would mask a useful default help for the instance container), nor is the help set specification checked, since someone should have installed the proper help set anyway, and the APIs cannot add a new reference to a help set automatically. See javax.help.HelpUtilities.getIDStringFromBean for details.

  Special IDs are added, corresponding to the class name, for all standard visual components.

  Parameters:

  instance - the instance to check for help (it is permissible for the InstanceCookie.instanceCreate() to return null)

  Returns:

  the help context found on the instance or inferred from a Bean, or null if none was found (or it was HelpCtx.DEFAULT_HELP)

• createClassLoader

  protected java.lang.ClassLoader createClassLoader​()

  Creates new NbClassLoader with restricted PermissionCollection that contains only: java.io.FilePermission("<<ALL FILES>>", "read") java.util.PropertyPermission("*", "read")

  Returns:

  ClassLoader
