javaPackageName

public static java.lang.String javaPackageName(java.net.URI codebase_oid)

Creates a mangled Java package name from a Fabric codebase oid.

Parameters:

codebase_oid - The oid of a codebase

Returns:

the parent package name for classes in the codebase

javaClassName

public static java.lang.String javaClassName(java.net.URI fclass_ref)

Return the mangled Java interface name for the Fabric class specified by the absolute name fclass_ref.

javaClassName

public static java.lang.String javaClassName(fabric.lang.FClass._Proxy fClass)

Return the mangled Java interface name of a Fabric class object.

javaImplName

public static java.lang.String javaImplName(java.net.URI fclass_ref)

Return the mangled Java Impl class name for the Fabric class specified by the absolute name fclass_ref.

javaProxyName

public static java.lang.String javaProxyName(java.net.URI fclass_ref)

Return the mangled Java Impl class name for the Fabric class specified by the absolute name fclass_ref.

toJavaImplName

public static java.lang.String toJavaImplName(java.lang.String className)

Returns the Java _Impl class name of a Fabric or FabIL class suitable for passing to ClassLoader.loadClass(). If className is the absolute name of a published Fabric class qualified by a fabric codebase URI, toJavaImplName will return a mangled java name.

Parameters:

className -

Returns:

toJavaProxyName

public static java.lang.String toJavaProxyName(java.lang.String className)

Returns the Java _Proxy class name of a Fabric or FabIL class suitable for passing to ClassLoader.loadClass(). If className is the absolute name of a published Fabric class qualified by a fabric codebase URI, toJavaImplName will return a mangled java name.

Parameters:

className -

Returns:

toJavaStaticName

public static java.lang.String toJavaStaticName(java.lang.String className)

Returns the Java _Static interface name of a Fabric or FabIL class suitable for passing to ClassLoader.loadClass(). If className is the absolute name of a published Fabric class qualified by a fabric codebase URI, toJavaImplName will return a mangled java name.

Parameters:

className -

Returns:

toJavaStaticImplName

public static java.lang.String toJavaStaticImplName(java.lang.String className)

Returns the Java _Static._Impl class name of a Fabric or FabIL class suitable for passing to ClassLoader.loadClass(). If className is the absolute name of a published Fabric class qualified by a fabric codebase URI, toJavaImplName will return a mangled java name.

Parameters:

className -

Returns:

toJavaStaticProxyName

public static java.lang.String toJavaStaticProxyName(java.lang.String className)

Returns the Java _Static._Proxy class name of a Fabric or FabIL class suitable for passing to ClassLoader.loadClass(). If className is the absolute name of a published Fabric class qualified by a fabric codebase URI, toJavaImplName will return a mangled java name.

Parameters:
