Direct Known Subclasses:

JavaArray, JavaClass

@Deprecated
public class JavaObject
extends RubyObject

Deprecated.

since 9.4

Java::JavaObject wrapping is no longer used with JRuby. The (automatic) Java proxy wrapping has been the preferred method for a while. Just keep using java.lang.Object.new as usual, without the manual JavaObject.wrap java_object.

Method Details

dataGetStruct

public final Object dataGetStruct()

Deprecated.

Description copied from interface: IRubyObject

Our version of Data_Get_Struct. Returns a wrapped data value if there is one, otherwise returns null.

Specified by:

dataGetStruct in interface IRubyObject

Overrides:

dataGetStruct in class RubyBasicObject

Returns:

the object wrapped.

See Also:

• IRubyObject.dataGetStruct()

dataWrapStruct

public final void dataWrapStruct(Object object)

Deprecated.

Description copied from interface: IRubyObject

Our version of Data_Wrap_Struct. This method will just set a private pointer to the object provided. This pointer is transient and will not be accessible from Ruby.

Specified by:

dataWrapStruct in interface IRubyObject

Overrides:

dataWrapStruct in class RubyBasicObject

Parameters:

object - the object to wrap

See Also:

• IRubyObject.dataWrapStruct(Object)

wrap

@Deprecated(since="9.4-")
public static JavaObject wrap(Ruby runtime,
 Object value)

Deprecated.

wrap

public static IRubyObject wrap(ThreadContext context,
 IRubyObject self,
 IRubyObject object)

Deprecated.

getJavaClass

public final Class<?> getJavaClass()

Deprecated.

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

getValue

public final Object getValue()

Deprecated.

createJavaObjectClass

public static RubyClass createJavaObjectClass(Ruby runtime,
 RubyClass Object,
 RubyModule javaModule)

Deprecated.

equals

public boolean equals(Object other)

Deprecated.

Description copied from class: RubyObject

This override does not do a "checked" dispatch.

Overrides:

equals in class RubyObject

Parameters:

other - object to compare

Returns:

true if equals

See Also:

• RubyBasicObject.equals(Object)

hashCode

public int hashCode()

Deprecated.

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()

hash

public RubyFixnum hash(ThreadContext context)

Deprecated.

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

to_s

public IRubyObject to_s(ThreadContext context)

Deprecated.

Overrides:

to_s in class RubyBasicObject

to_s

@Deprecated(since="10.0")
public static IRubyObject to_s(Ruby runtime,
 Object dataStruct)

Deprecated.

op_equal

@Deprecated(since="10.0")
public IRubyObject op_equal(IRubyObject other)

Deprecated.

op_equal

public IRubyObject op_equal(ThreadContext context,
 IRubyObject other)

Deprecated.

Description copied from class: RubyBasicObject

rb_obj_equal Will by default use identity equality to compare objects. This follows the Ruby semantics. The name of this method doesn't follow the convention because hierarchy problems

Specified by:

op_equal in interface IRubyObject

Overrides:

op_equal in class RubyBasicObject

op_equal

@Deprecated(since="10.0")
public static RubyBoolean op_equal(JavaProxy self,
 IRubyObject other)

Parameters:

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

Returns:

java type
