Description copied from interface: ComponentFactory

Create a new component adapter based on the specified arguments.

Parameters:

monitor - the component monitor

lifecycleStrategy - te lifecycle strategy

componentProperties - the component properties

componentKey - the key to be associated with this adapter. This value should be returned from a call to ComponentAdapter.getComponentKey() on the created adapter.

componentImplementation - the implementation class to be associated with this adapter. This value should be returned from a call to ComponentAdapter.getComponentImplementation() on the created adapter. Should not be null.

parameters - additional parameters to use by the component adapter in constructing component instances. These may be used, for example, to make decisions about the arguments passed into the component constructor. These should be considered hints; they may be ignored by some implementations. May be null, and may be of zero length.

Returns:

a new component adapter based on the specified arguments. Should not return null.

Throws:

PicoCompositionException - if the creation of the component adapter results in a PicoCompositionException.
