Column Data Accessor
Identifier:
org.eclipse.wst.rdb.data.core.columnDataAccessor
Since:
This extension point is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
Description:
The columnDataAccessor allows to contribute an IColumnDataAccessor object to be used with a particular vendor, version and datatype.
The contributed object is then used to perform the data access in the table editor, allowing to implement support for database-specific data types.

This element specifies an IColumnDataAccessor to be used with a combination of vendor/version/data type.
If several contributions matches a given column, the most specific contribution is used (the one that specifies the highest number of criteria).
- vendor - Vendor ID: 'product' attribute from the org.eclipse.wst.rdb.core.databaseDefinition extension.
Ommit to match all vendors, or separate multiple vendors with commas.
- version - Version ID: 'version' attribute from the org.eclipse.wst.rdb.core.databaseDefinition extension.
Ommit to match all versions, or separate multiple versions with commas.
- dataType - Data type ID: type name from the product xmi definition.
Ommit to match all data types, or separate multiple data types with commas.
- class - A class that implements IColumnDataAccessor.
