Package org.smooks

Class Smooks

java.lang.Object

org.smooks.Smooks

All Implemented Interfaces:

Closeable, AutoCloseable

@ThreadSafe
public class Smooks
extends Object
implements Closeable

Smooks executor class.

Additional configurations can be carried out on the Smooks instance through the SmooksUtil class.

The basic usage scenario for this class might be as follows:

1. Develop (or reuse) an implementation of ElementVisitor to perform some transformation/analysis operation on a message. There are a number of prebuilt and reuseable implemntations available as "Smooks Cartridges".
2. Write a resource configuration to target the ElementVisitor implementation at the target fragment of the message being processed.
3. Apply the logic as follows:

    Smooks smooks = new Smooks("smooks-config.xml");
    ExecutionContext execContext;
   
    execContext = smooks.createExecutionContext();
    smooks.filter(new StreamSource(...), new StreamSink(...), execContext);
    

Remember, you can implement and apply multiple ElementVisitor within the context of a single filtering operation. You can also target DOMElementVisitors/ElementVisitor based on target profiles, and so use a single configuration to process multiple messages by sharing profiles across your message set.

createExecutionContext

public org.smooks.api.ExecutionContext createExecutionContext()

Create a ExecutionContext instance for use on this Smooks instance.

The created context is profile agnostic and should be used where profile based targeting is not in use.

The context returned from this method is used in subsequent calls to filterSource(ExecutionContext, org.smooks.api.io.Source, org.smooks.api.io.Sink...) It allows access to the execution context instance before and after calls on this method. This means the caller has an opportunity to set and get data bound to the execution context (before and after the calls), providing the caller with a mechanism for interacting with the content filtering phases.

Returns:

Execution context instance.

createExecutionContext

public org.smooks.api.ExecutionContext createExecutionContext(String targetProfile)
                                                       throws org.smooks.api.profile.UnknownProfileMemberException

Create a ExecutionContext instance for use on this Smooks instance.

The created context is profile aware and should be used where profile based targeting is in use. In this case, the transfromation/analysis resources must be configured with profile targeting information.

The context returned from this method is used in subsequent calls to filterSource(ExecutionContext, org.smooks.api.io.Source, org.smooks.api.io.Sink...). It allows access to the execution context instance before and after calls on this method. This means the caller has an opportunity to set and get data bound to the execution context (before and after the calls), providing the caller with a mechanism for interacting with the content filtering phases.

Parameters:

targetProfile - The target profile (base profile) on behalf of whom the filtering/serialisation filter is to be executed.

Returns:

Execution context instance.

Throws:

org.smooks.api.profile.UnknownProfileMemberException - Unknown target profile.
