| MethodInvocationBatch | | public class MethodInvocationBatch implements Batch,Serializable(Code) | | This class provides a

| Method Summary | |
| public void | addInvocation(Object obj, String method, String[] argTypes, Object[] args)
Adds a method invocation to the batch.
Parameters:
obj - the objects whose method is to be invoked.
Parameters:
method - the method name.
Parameters:
argTypes - the argument types as strings suitable forClassLoader.loadClass. | | public void | addInvocation(int result, String method, String[] argTypes, Object[] args, boolean discard)
Adds a method invocation on a previous result to the batch. | | public Object | execute(Context ctx)
Executes the registered method invocations one by one in a
single transaction. |
| MethodInvocationBatch | | public MethodInvocationBatch()(Code) | | Create a new empty method invocation batch. Equivalent to
MethodInvocationBatch(false).
|
| MethodInvocationBatch | | public MethodInvocationBatch(boolean stopOnException)(Code) | | Create a new empty method invocation batch. The flag passed as
parameter controls if an exception stops the batch execution.
Parameters:
stopOnException - if true execution isinterrupted on the first encountered exception |
| addInvocation | | public void addInvocation(Object obj, String method, String[] argTypes, Object[] args)(Code) | | Adds a method invocation to the batch.
Parameters:
obj - the objects whose method is to be invoked.
Parameters:
method - the method name.
Parameters:
argTypes - the argument types as strings suitable forClassLoader.loadClass. May be nullwhich is interpreted as "no parameters".
Parameters:
args - the actual arguments. May be nullwhich is interpreted as "no parameters". |
| addInvocation | | public void addInvocation(int result, String method, String[] argTypes, Object[] args, boolean discard)(Code) | | Adds a method invocation on a previous result to the batch.
Parameters:
result - relative index of the result to be usedfor method invovation, i.e. -1 is the previous result.
Parameters:
method - the method name.
Parameters:
argTypes - the argument types as strings suitable forClassLoader.loadClass. May be nullwhich is interpreted as "no parameters".
Parameters:
args - the actual arguments. May be nullwhich is interpreted as "no parameters".
Parameters:
discard - if true the referenced result willbe removed from the result list. |
| execute | | public Object execute(Context ctx)(Code) | | Executes the registered method invocations one by one in a
single transaction. Note that execution is terminated if an
invoked method sets rollback only.
Parameters:
ctx - the execution context. the execution result, which is of type ResultResult. |
