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:

the Ruby singleton class

getJavaClass

public java.lang.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 java.lang.Object constant()

Specified by:

constant in interface Constantizable

See Also:

Constantizable

createFalseClass

public static RubyClass createFalseClass(Ruby runtime)

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

marshalTo

public void marshalTo(MarshalStream output)
               throws java.io.IOException

Throws:

java.io.IOException

taint

@Deprecated
public IRubyObject taint(ThreadContext context)

Deprecated.

Overrides:
