Class MockContext

java.lang.Object

org.mockejb.jndi.MockContext

All Implemented Interfaces:

javax.naming.Context

public class MockContext
extends java.lang.Object
implements javax.naming.Context

Provides implementation of javax.naming.Context interface for hierarchical in memory single-namespace naming system. A name in the MockContext namespace is a sequence of one or more atomic names, relative to a root initial context. When a name consist of more than one atomic names it is a CompoundName where atomic names are separated with separator character - '/' or '.'. It is possible to use both separator characters in the same name. In such cases any occurrences of '.' are replaced with '/' before parsing.

Leading and terminal components of a CompoundName can not be empty - for example "name1/name2/name3" is a valid name, while the following names are not valid - "/name1/name2/name3", "name1/name2/name3/", "/name1/name2/name3/". If such name is passed, all empty leading/terminal components will be removed before the name is actually used (this will not affect the original value) - from the above three examples the actual name will be "name1/name2/name3". If a name contains intermediate empty components (for example "a//b") then InvalidNameException will be thrown.

Composite names (instances of CompositeName) must contain zero or one component from the MockContext namespace.

The namespace of MockContext can be represented as a tree of atomic names. Each name is bound to an instance of MockContext (subcontext) or to an arbitrary object. Each subcontext has collection of names bound to other subcontexts or arbitrary objects.

When instance of Name is used as parameter to any of the MockContext methods, if the object is not CompositeName then it is assumed that it is CompoundName

Example:

 myContext = initialContext.lookup("foo");
 myObject = myContext.lookup("bar");
 
 is equivalent to
 myObject = initialContext.lookup("foo/bar");
 

Instances of MockContext are created only through MockContextFactory, when InitialContext is instantiated.

If a remote context is provided, this class will search in that remote context if the object is not found locally.

For overloaded methods that accept name as String or Name only the version for Name is documented. The String version creates CompoundName, from the string name passed as parameter, and calls the Name version of the same method.
