Method Detail

convertToJavaArray

public static IRubyObject[] convertToJavaArray(IRubyObject value)

convertToRubyArray

public static RubyArray convertToRubyArray(Ruby runtime,
                                           IRubyObject value,
                                           boolean coerce)

This name may be a bit misleading, since this also attempts to coerce array behavior using to_ary.

Parameters:

runtime - The JRuby runtime

value - The value to convert

coerce - Whether to coerce using to_ary or just wrap with an array

convertToRubyArrayWithCoerce

public static RubyArray convertToRubyArrayWithCoerce(Ruby runtime,
                                                     IRubyObject value)

convertToRubyArray19

public static RubyArray convertToRubyArray19(Ruby runtime,
                                             IRubyObject value,
                                             boolean coerce)

convertToRubyArrayWithCoerce19

public static RubyArray convertToRubyArrayWithCoerce19(Ruby runtime,
                                                       IRubyObject value)

popArray

public static IRubyObject[] popArray(IRubyObject[] array)

Remove first element from array

Parameters:

array - to have first element "popped" off

Returns:

all but first element of the supplied array

arrayLength

public static int arrayLength(IRubyObject node)

getOptionsArg

public static IRubyObject getOptionsArg(Ruby runtime,
                                        IRubyObject... args)
