  - dataGetStruct
```
public final Object dataGetStruct()
```
    Description copied from interface: IRubyObject
    
    Our version of Data_Get_Struct. Returns a wrapped data value if there is one, otherwise returns null.
    
    Specified by:
    
    dataGetStruct in interface IRubyObject
    
    Overrides:
    
    dataGetStruct in class RubyBasicObject
    
    Returns:
    
    the object wrapped.
    
    See Also:
    
    IRubyObject.dataGetStruct()
  - dataWrapStruct
```
public final void dataWrapStruct(Object object)
```
    Description copied from interface: IRubyObject
    
    Our version of Data_Wrap_Struct. This method will just set a private pointer to the object provided. This pointer is transient and will not be accessible from Ruby.
    
    Specified by:
    
    dataWrapStruct in interface IRubyObject
    
    Overrides:
    
    dataWrapStruct in class RubyBasicObject
    
    Parameters:
    
    object - the object to wrap

  - getJavaClass
```
public final Class<?> getJavaClass()
```
    Description copied from class: RubyBasicObject
    
    Will return the Java interface that most closely can represent this object, when working through JAva integration translations.
    
    Specified by:
    
    getJavaClass in interface IRubyObject
    
    Overrides:
    
    getJavaClass in class RubyBasicObject
    
    Returns:

  - equals
```
public boolean equals(Object other)
```
    Description copied from class: RubyObject
    
    This override does not do a "checked" dispatch.
    
    Overrides:
    
    equals in class RubyObject
    
    See Also:
    
    RubyBasicObject.equals(Object)
  - hashCode
```
public int hashCode()
```
    Description copied from class: RubyObject
    
    This override does not do "checked" dispatch since Object usually has #hash defined.
    
    Overrides:
    
    hashCode in class RubyObject
    
    See Also:
    
    RubyBasicObject.hashCode()
  - hash
```
public RubyFixnum hash()
```
    Description copied from class: RubyBasicObject
    
    rb_obj_id Will return the hash code of this object. In comparison to MRI, this method will use the Java identity hash code instead of using rb_obj_id, since the usage of id in JRuby will incur the cost of some. ObjectSpace maintenance.
    
    Overrides:
    
    hash in class RubyBasicObject
  - to_s
```
public IRubyObject to_s()
```
    Description copied from class: RubyBasicObject
    
    rb_any_to_s call-seq: obj.to_s => string Returns a string representing obj. The default to_s prints the object's class and an encoding of the object id. As a special case, the top-level object that is the initial execution context of Ruby programs returns ``main.''

```
    Description copied from interface: IRubyObject
