B.1 EL Properties of Oracle ADF Bindings

Table B-1 shows the properties that you can use in EL expressions to access values of the ADF binding objects at runtime. The properties appear in alphabetical order.

Note:

When you use the EL Expression Builder dialog in JDeveloper, you may see properties listed below the ADF bindings and ADF data variables that do not appear in this appendix. Properties that do not appear in this appendix will become deprecated in a future release. For the full list of deprecated binding properties, please refer to the JDeveloper Release Note.

`fullName`	Returns the fully qualified name of the binding object in the Oracle ADF binding context.	yes	yes	yes	yes	yes	yes	yes
`inputValue`	Returns the value of the first attribute to which the binding is associated. If the binding was used to set the value on the attribute and the set operation failed, this method returns the invalid value that was being set.	n/a	n/a	yes	yes	yes	yes	yes
`iteratorBinding`	Returns the iterator binding that provides access to the data collection.	n/a	yes	yes	yes	yes	yes	yes

`rangeSet`	Returns a list of map elements over the range of rows from the associated iterator binding. The elements in this list are wrapper objects over the indexed row in the range that restricts access to only the attributes to which the binding is bound.

Returns "*" if the current entry belongs to the current row; otherwise, returns " ". This property is useful in JSP applications to display the current row. `attributeValues` — The array of applicable attribute values from the row.
