Enclosing class:

public static interface OptoFactory.ConstantFactory

A factory for abstract "constant" representations of objects. This is currently only used by our invokedynamic support to cache the "constant" handles that wrap common literal fixnums and symbols. See #2058.

java.lang.Object create(java.lang.Class type,
                        java.lang.Object object)

Parameters:

type - the type to which the constant should conform

object - the object which represents the constant's value

Returns:

a constant representation suitable for optimization
