==Description==

Field element is used by [[Data providers]]. Allows to define the key and direction of the Expression defined above.

=={{GVESB}} Configuration==

The Field Element is used by: [[ArrayDataProvider]], [[Axis2MessageContextDataProvider]], [[Axis2SAAJSOAPMessageDataProvider]], [[CollectionDataProvider]], [[HttpMethodDataProvider]], [[InputStreamDataProvider]], [[JMSBytesMessageDataProvider]], [[JMSMapMessageDataProvider]], [[JMSObjectMessageDataProvider]], [[JMSStreamMessageDataProvider]], [[JMSTextMessageDataProvider]], [[MapDataProvider]], [[ObjectDataProvider]], [[StringDataProvider]], [[XMLEventCollectionDataProvider]].

The following table shows the Field element's attributes:
{|class="gvtable"
! Attribute !! Type !! Description
|-
| key || required || The attribute's value can't be null.
|-
| type || fixed || This attribute must assume the value '''field'''.
|-
| direction || optional || Field direction.
* INOUT: The expression is evaluated on the object set (usually the current [[GVBuffer]], unless otherwise specified
by the attribute 'source-selector') the value returned by the expression, is added to the context with the prefix 'key_' +
@key, and set the data provider to be returned in the output.
* IN : The expression is evaluated on the object set (usually the current [[GVBuffer]], unless otherwise specified by
the attribute 'source-selector') the value returned by the expression is added to the context with the prefix 'key_' + @key.
* OUT : The expression is evaluated directly on the object that is returned by the [[Data provider]].

In all cases, two variables are added to the context:
* Input: object setted, usually the current [[GVBuffer]], which will not be overwritten from attribute 'source-selector';
* Output: the object that is returned by the [[Data provider]].
|}

Contains a sub-element [[#Expression|Expression]].
