getDefaultValue

public static java.lang.Object getDefaultValue(java.lang.reflect.Type paramType)

hasIllegalTypeNameChars

public static boolean hasIllegalTypeNameChars(java.lang.String typeName)

Tests whether a type name carries a character that cannot appear in a Java binary class name but is meaningful in a URL. A nested jar URL such as jar:http://host/x.jar!/ is resolvable by some class loaders, so a type name carrying one must never reach one.

Every autoType entry point shares this predicate; validating in only some of them is the asymmetry that lets a type name reach a class loader through the unchecked path.

Internal, public only because the autoType entry points live in different packages.

Parameters:

typeName - the type name to test

Returns:

true if the type name must be rejected without being resolved

normalizeAcceptName

public static java.lang.String normalizeAcceptName(java.lang.String typeName)

Normalizes a type name the way the autoType accept-list rolling hash normalizes it, so that a nested class matches whether it is written with its binary name (a.b.Outer$Inner) or its canonical name (a.b.Outer.Inner). Following that existing rolling-hash rule means the two spellings are equivalent as accept entries.

Internal, public only because the autoType entry points live in different packages.

Parameters:

typeName - the type name to normalize

Returns:

the normalized type name
