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)

Method Details

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:

the Ruby singleton class

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:

the true Java class of this (Ruby) object

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)

newBoolean

public static RubyBoolean newBoolean(ThreadContext context,
 boolean value)

hash

public RubyFixnum hash(ThreadContext context)

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()

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:

the object id

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
