Methods

Modifier and Type	Method and Description
Object	constant()
static RubyClass	createFalseClass(Ruby runtime)
static RubyClass	createTrueClass(Ruby runtime)
Class<?>	getJavaClass() Will return the Java interface that most closely can represent this object, when working through JAva integration translations.
ClassIndex	getNativeClassIndex() This is overridden in the other concrete Java builtins to provide a fast way to determine what type they are.
RubyClass	getSingletonClass() rb_singleton_class Note: this method is specialized for RubyFixnum, RubySymbol, RubyNil and RubyBoolean Will either return the existing singleton class for this object, or create a new one and return that.
RubyFixnum	hash(ThreadContext context)
int	hashCode() Override the Object#hashCode method to make sure that the Ruby hash is actually used as the hashcode for Ruby objects.
RubyFixnum	id() rb_obj_id Return the internal id of an object.
boolean	isImmediate() Is object immediate (def: Fixnum, Symbol, true, false, nil?).
void	marshalTo(MarshalStream output)
static RubyBoolean	newBoolean(Ruby runtime, boolean value)
IRubyObject	taint(ThreadContext context) rb_obj_taint call-seq: obj.taint -> obj Marks obj as tainted---if the $SAFE level is set appropriately, many method calls which might alter the running programs environment will refuse to accept tainted strings.
Object	toJava(Class target) Convert the object to the specified Java class, if possible.

Method Detail

getNativeClassIndex

public ClassIndex getNativeClassIndex()

Description copied from class: RubyObject

This is overridden in the other concrete Java builtins to provide a fast way to determine what type they are. Will generally return a value from org.jruby.runtime.ClassIndex

Specified by:

getNativeClassIndex in interface CoreObjectType

Overrides:

getNativeClassIndex in class RubyObject

See Also:

ClassIndex

isImmediate

public boolean isImmediate()

Description copied from class: RubyBasicObject

Is object immediate (def: Fixnum, Symbol, true, false, nil?).

Specified by:

isImmediate in interface IRubyObject

Overrides:

isImmediate in class RubyBasicObject

Returns:

getSingletonClass

public RubyClass getSingletonClass()

Description copied from class: RubyBasicObject

rb_singleton_class Note: this method is specialized for RubyFixnum, RubySymbol, RubyNil and RubyBoolean Will either return the existing singleton class for this object, or create a new one and return that.

Specified by:

getSingletonClass in interface IRubyObject

Overrides:

getSingletonClass in class RubyBasicObject

Returns:

RubyClass

getJavaClass

public 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:

Class

constant

public Object constant()

Specified by:

constant in interface Constantizable

See Also:

Constantizable

createFalseClass

public static RubyClass createFalseClass(Ruby runtime)

createTrueClass

public static RubyClass createTrueClass(Ruby runtime)

newBoolean

public static RubyBoolean newBoolean(Ruby runtime,
                     boolean value)

hash

public RubyFixnum hash(ThreadContext context)

hashCode

public int hashCode()

Description copied from class: RubyObject

Override the Object#hashCode method to make sure that the Ruby hash is actually used as the hashcode for Ruby objects. If the Ruby "hash" method doesn't return a number, the Object#hashCode implementation will be used instead.

Overrides:

hashCode in class RubyObject

id

public RubyFixnum id()

Description copied from class: RubyBasicObject

rb_obj_id Return the internal id of an object.

Specified by:

id in interface IRubyObject

Overrides:

id in class RubyBasicObject

Returns:

taint

public IRubyObject taint(ThreadContext context)

Description copied from class: RubyBasicObject

rb_obj_taint call-seq: obj.taint -> obj Marks obj as tainted---if the $SAFE level is set appropriately, many method calls which might alter the running programs environment will refuse to accept tainted strings.

Overrides:

taint in class RubyBasicObject

marshalTo

public void marshalTo(MarshalStream output)
               throws IOException

Throws:

IOException

toJava

public Object toJava(Class target)

Description copied from interface: IRubyObject

Convert the object to the specified Java class, if possible.

Specified by:

toJava in interface IRubyObject

Overrides:

toJava in class RubyBasicObject

Parameters:

target - The target type to which the object should be converted.
