Method Details

dataGetStruct

public final Object dataGetStruct()

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)

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

public static JavaObject wrap(Ruby runtime,
 Object value)

wrap

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

getJavaClass

public final 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

getValue

public final Object getValue()

createJavaObjectClass

public static RubyClass createJavaObjectClass(Ruby runtime,
 RubyModule javaModule)

registerRubyMethods

protected static void registerRubyMethods(Ruby runtime,
 RubyClass JavaObject)

equals

public boolean equals(Object other)

Description copied from class: RubyObject

This override does not do a "checked" dispatch.

Overrides:

equals in class RubyObject

See Also:

• RubyBasicObject.equals(Object)

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()

hash

public RubyFixnum hash()

Description copied from class: RubyBasicObject

rb_obj_id 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

to_s

public IRubyObject to_s()

Description copied from class: RubyBasicObject

rb_any_to_s call-seq: obj.to_s => string Returns a string representing obj. The default to_s prints the object's class and an encoding of the object id. As a special case, the top-level object that is the initial execution context of Ruby programs returns ``main.''

Overrides:

to_s in class RubyBasicObject

to_s

public static IRubyObject to_s(Ruby runtime,
 Object dataStruct)

op_equal

public IRubyObject op_equal(IRubyObject other)

op_equal

public static RubyBoolean op_equal(JavaProxy self,
 IRubyObject other)

equals

private static RubyBoolean equals(Ruby runtime,
 Object thisValue,
 IRubyObject other)

same

public IRubyObject same(IRubyObject other)

unwrapObject

private static Object unwrapObject(IRubyObject wrapped,
 Object defaultValue)

java_type

public RubyString java_type()

java_class

@Deprecated
public JavaClass java_class()

Deprecated.

get_java_class

public IRubyObject get_java_class()

length

public RubyFixnum length()

is_java_proxy

public IRubyObject is_java_proxy()

ruby_synchronized

public final IRubyObject ruby_synchronized(ThreadContext context,
 Block block)

ruby_synchronized

public static IRubyObject ruby_synchronized(ThreadContext context,
 Object lock,
 Block block)

marshal_dump

public IRubyObject marshal_dump(ThreadContext context)

marshal_load

public IRubyObject marshal_load(ThreadContext context,
 IRubyObject str)

toJava

public <T> T toJava(Class<T> 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.

• IRubyObject.toJava(java.lang.Class<T>)
