Method Detail

resolveType

IType resolveType(IType target,
                  IType source)

This method should produce a more appropriately parameterized type for the given target type for this coercion. This allows a coercion to communicate type information through the coercion process. An example is the MetaType-to-Class coercion. MetaType should be interpreted as Class from a type inference perspective, so this give the coercer a chance to let the compiler know so.

If no more appropriate inference type exists, this method should return the source type.

Parameters:

target - type

source -

Returns:

a possibly more appropriately parameterized type or the source type if not
