checkData

public static IRubyObject checkData(IRubyObject obj)

Checks that this object is of type DATA and then returns it, otherwise raises failure (MRI: Check_Type(obj, T_DATA))

Parameters:

obj - the object to check

Returns:

typeAsString

public static RubyString typeAsString(IRubyObject obj)

checkID

public static RubySymbol checkID(IRubyObject obj)

Convert the supplied object into an internal identifier String. Basically, symbols are stored internally as raw bytes from whatever encoding they were originally sourced from. When methods are stored they must also get stored in this same raw fashion so that if we use symbols to look up methods or make symbols from these method names they will match up. For 2.2 compatibility, we also force all incoming identifiers to get anchored as hard-referenced symbols.

checkID

public static RubySymbol checkID(Ruby runtime,

                                                 java.lang.String convertMethod)
