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

Returns:

the ClassIndex of the native type this object was constructed from

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:

boolean

singletonClass

public RubyClass singletonClass(ThreadContext context)

Description copied from class: RubyBasicObject

Will either return the existing singleton class for this object, or create a new one and return that. For a few types a singleton class is not possible so it will throw an error.

Specified by:

singletonClass in interface IRubyObject

Overrides:

singletonClass in class RubyBasicObject

Parameters:

context - the current thread context

Returns:

the singleton of this type

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

finishFalseClass

public static void finishFalseClass(ThreadContext context,
 RubyClass False)

finishTrueClass

public static void finishTrueClass(ThreadContext context,
 RubyClass True)

newBoolean

@Deprecated
public static RubyBoolean newBoolean(Ruby runtime,
 boolean value)

Deprecated.

newBoolean

@Deprecated
public static RubyBoolean newBoolean(ThreadContext context,
 boolean value)

Deprecated.

appendIntoString

public void appendIntoString(RubyString target)

Specified by:

appendIntoString in interface Appendable

hash

public RubyFixnum hash(ThreadContext context)

Description copied from class: RubyBasicObject

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

Parameters:

context - the current thread context

Returns:

the hash value

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

Returns:

the hash code

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

@Deprecated(since="10.0",
            forRemoval=true)
public void marshalTo(MarshalStream output)
               throws IOException

Deprecated, for removal: This API element is subject to removal in a future version.

Throws:

IOException

taint

@Deprecated
public IRubyObject taint(ThreadContext context)

Deprecated.

Overrides:

taint in class RubyBasicObject
