IContainer createInstance(ContainerTypeDescription description, java.lang.Object[] parameters) throws ContainerCreateException
ContainerFactory.getDefault().createContainer("foocontainer",new Object { "hello" });
description
- the ContainerTypeDescription associated with the registered
container provider implementationparameters
- parameters specified by the caller. May be null if no
parameters are passed in by caller to
ContainerFactory.getDefault().createContainer(...)
ContainerCreateException
java.lang.String[] getSupportedAdapterTypes(ContainerTypeDescription description)
IContainer.getAdapter(Class)
with the same type name as a
returned value will return a non-null
result. In other
words, even if the class name is in the returned array, subsequent calls
to IContainer.getAdapter(Class)
may still return
null
.

- the ContainerTypeDescription to report adapters for. Must not
be null
.
null
may be returned by
the provider if no adapters are supported for this description.java.lang.Class[][] getSupportedParameterTypes(ContainerTypeDescription description)
createInstance(ContainerTypeDescription, Object[])
.
Each of the rows of the returned array specifies a Class[] of parameter types. These parameter types correspond to the types of Object[] that can be passed into the second parameter of
createInstance(ContainerTypeDescription, Object[])
.
Consider the following example:
public Class[][] getSupportedParameterTypes() { return new Class[][] { { String.class }, { String.class, String.class } }; }The above means that there are two acceptable values for the Object [] passed into
createInstance(ContainerTypeDescription, Object[])
:
1) a single String, and 2) two Strings. These would therefore be
acceptable as input to createInstance:
IContainer container = ContainerFactory.getDefault().createContainer( description, new Object[] { "Hello" }); IContainer container2 = ContainerFactory.getDefault().createContainer( description, new Object[] { "Hello" });
