Interface MetadataParamsFilter

All Known Implementing Classes:
DefaultMetadataParamsFilter
@SPI public interface MetadataParamsFilter
This filter applies an either 'include' or 'exclude' policy with 'include' having higher priority. That means if 'include' is specified then params specified in 'exclude' will be ignored If multiple Filter extensions are provided, then, 1. All params specified as should be included within different Filter extension instances will determine the params that will finally be used. 2. If none of the Filter extensions specified any params as should be included, then the final effective params would be those left after removed all the params specified as should be excluded. It is recommended for most users to use 'exclude' policy for service params and 'include' policy for instance params. Please use 'params-filter=-default, -filterName1, filterName2' to activate or deactivate filter extensions.
