GVThrowException element stops the Flow with an exception.

=={{GVESB}} Configuration==

The element GVThrowException is used in a [[GVEndNode]] and allows to stop the workflow of {{GVESB}} with exception.

Exceptions are allowed only of type '''it.greenvulcano.gvesb.buffer.GVException''' and its subclasses.

The exception-id attribute or value can contain [[placeholders|metadata]] to be replaced with fields of any [[GVBuffer]] in the execution environment. The parameters are always written in ${param} format.

The possible parameters are:

For a [[GVBuffer]] object
* for standard fields, the field name
* ${GVBuffer.system}
* ${GVBuffer.service}
* ${GVBuffer.id}
* ${GVBuffer.retCode}

For properties:
* ${GVBuffer.property:}
* ${GVBuffer.properties} (return all the properties, in the form name: 'filedName' value: 'fieldValue')

All [[placeholders|metadata]] are written in accordance with the above format.
If an error occurs the [[placeholders|metadata]] will not be replaced.
The GVThrowException Element is used by: GVEndNode.
The following table shows the GVThrowException element's attributes:
{|class="gvtable"
! Attribute !! Type !! Description
|-
| exception-id || required || ID of the exception.
|-
| class || optional || Exception class.
Exceptions are allowed only of type '''it.greenvulcano.gvesb.buffer.GVException''' and its subclass.
