Package com.sun.corba.ee.impl.resolver

Class INSURLOperationImpl

java.lang.Object

com.sun.corba.ee.impl.resolver.INSURLOperationImpl

All Implemented Interfaces:

Operation

public class INSURLOperationImpl
extends Object
implements Operation

This class provides an Operation that converts from CORBA INS URL strings into CORBA object references. It will eventually become extensible, but for now it simply encapsulates the existing implementation. Once the full extensibility is in place, we want this operation to convert string to INSURL, which has mainly a public resolver method that returns an object reference.

Method Details

getIORFromString

private Object getIORFromString(String str)

This static method takes a Stringified IOR and converts it into IOR object. It is the caller's responsibility to only pass strings that start with "IOR:".

operate

public Object operate(Object arg)

Description copied from interface: Operation

Apply some function to a value and return the result.

Specified by:

operate in interface Operation

Parameters:

arg - value to apply function to

Returns:

result of function

resolveINSURL

private Object resolveINSURL(INSURL theURLObject)

resolveCorbaloc

private Object resolveCorbaloc(CorbalocURL theCorbaLocObject)

resolves a corbaloc: url that is encapsulated in a CorbalocURL object.

Returns:

the CORBA.Object if resolution is successful

resolveCorbaname

private Object resolveCorbaname(CorbanameURL theCorbaName)

resolves a corbaname: url that is encapsulated in a CorbanameURL object.

Returns:

the CORBA.Object if resolution is successful

getIORUsingCorbaloc

private Object getIORUsingCorbaloc(INSURL corbalocObject)

This is an internal method to get the IOR from the CorbalocURL object.

Returns:

the CORBA.Object if resolution is successful

getDefaultRootNamingContext

private NamingContextExt getDefaultRootNamingContext()

This is required for corbaname: resolution. Currently we are not caching RootNamingContext as the reference to rootNamingContext may not be Persistent in all the implementations. _REVISIT_ to clear the rootNamingContext in case of COMM_FAILURE.

Returns:

the org.omg.COSNaming.NamingContextExt if resolution is successful

clearRootNamingContextCache

private void clearRootNamingContextCache()

A utility method to clear the RootNamingContext, if there is an exception in resolving CosNaming:Name from the RootNamingContext,
