Constructor Detail

JavaObject

public JavaObject(java.lang.Object obj)

JavaObject

public JavaObject(java.lang.Object obj,
                  java.lang.Class<?> intendedClass)

Constructs a Java Object with the given intended class, used to access the object reflectively. If the class represents a primitive type, the corresponding wrapper type is used instead.

Throws:

java.lang.ClassCastException - if the object is not an instance of the intended class.

Method Detail

typeOf

public LispObject typeOf()

Overrides:

typeOf in class LispObject

classOf

public LispObject classOf()

Overrides:

classOf in class LispObject

typep

public LispObject typep(LispObject type)

Overrides:

typep in class LispObject

STRING

public LispObject STRING()

Overrides:

STRING in class LispObject

getObject

public final java.lang.Object getObject()

getInstance

public static final LispObject getInstance(java.lang.Object obj)

Encapsulates obj, if required. If obj is a LispObject, it's returned as-is.

Parameters:

obj - Any java object

Returns:

obj or a new JavaObject encapsulating obj

getInstance

public static final LispObject getInstance(java.lang.Object obj,
                                           java.lang.Class<?> intendedClass)

Encapsulates obj, if required. If obj is a LispObject, it's returned as-is. If not, a java object with the specified intended class is returned.

Parameters:

obj - Any java object

intendedClass - the class that shall be used to access obj

Returns:

obj or a new JavaObject encapsulating obj

getInstance

public static final LispObject getInstance(java.lang.Object obj,
                                           boolean translated)

Encapsulates obj, if required. If obj is a LispObject, it's returned as-is. If obj is of a type which can be mapped to a lisp type, an object of the mapped type is returned, if translated is true.

Parameters:

obj -

translated -

Returns:

a LispObject representing or encapsulating obj

getInstance

public static final LispObject getInstance(java.lang.Object obj,
                                           boolean translated,
                                           java.lang.Class<?> intendedClass)

Encapsulates obj, if required. If obj is a LispObject, it's returned as-is. If obj is of a type which can be mapped to a lisp type, an object of the mapped type is returned, if translated is true.

Parameters:

obj -

translated -

intendedClass - the class that shall be used to reflectively access obj; it is an error for obj not to be an instance of this class. This parameter is ignored if translated == true and the object can be converted to a Lisp object.

Returns:

a LispObject representing or encapsulating obj

javaInstance

public java.lang.Object javaInstance()

Overrides:

javaInstance in class LispObject

javaInstance

public java.lang.Object javaInstance(java.lang.Class<?> c)

Overrides:

javaInstance in class LispObject

lockableInstance

public java.lang.Object lockableInstance()

Returns the encapsulated Java object for interoperability with wait, notify, synchronized, etc.

Overrides:

lockableInstance in class LispObject

Returns:

The encapsulated object

getIntendedClass

public java.lang.Class<?> getIntendedClass()

getObject

public static final java.lang.Object getObject(LispObject o)

equal

public final boolean equal(LispObject other)

Overrides:

equal in class LispObject

equalp

public final boolean equalp(LispObject other)

Overrides:

equalp in class LispObject

Overrides:

sxhash in class LispObject

printObject

public java.lang.String printObject()

Overrides:

printObject in class LispObject

getDescription

public LispObject getDescription()

Overrides:

getDescription in class LispObject

getParts

public LispObject getParts()

Description copied from class: LispObject

Implementing the getParts() protocol will allow INSPECT to return information about the substructure of a descendent of LispObject. The protocol is to return a List of Cons pairs, where the car of each pair contains a decriptive string, and the cdr returns a subobject for inspection.

Overrides:

getParts in class LispObject

Executes a function recursively over and its superclasses and interfaces.

mapcarClassHierarchy

public static LispObject mapcarClassHierarchy(java.lang.Class<?> clss,
                                              LispObject fn)

describeJavaObject

public static java.lang.String describeJavaObject(JavaObject javaObject)

registerJavaClass

public static LispObject registerJavaClass(java.lang.Class<?> javaClass,
                                           LispObject classMetaObject)

findJavaClass
