Table implementation backed by a registered KCriteria builder, rendering the result of running that criteria query as rows with one column per configured property path. Created from XStream persisted configuration (aliased "table") or ad hoc through QueriesFolder.createCriteriaQuery, then saved via QueryManager.saveTable and looked up like any other Table when a report runs.
Implements: Table
Properties
| Property | Returns | Description |
|---|---|---|
| description | String | Description for this table. Always returns null, as criteria tables do not carry a separate description. |
| headers | List<String> | Column header labels, one per configured column, taken from each column's text. |
| tableId | String | The table id, matching the id of the KCriteria builder this table runs and the key it is looked up under via QueryManager.getTable. |
Inherited from Table
Methods
getRows(int start, Integer maxRows)
Returns: RowsResult
Reads a page of rows starting at the given row, discarding any progress status. Delegates to the three argument overload with a status callback that does nothing.
| Parameter | Description |
|---|---|
start | the zero based index of the first row to return |
maxRows | the maximum number of rows to return, or null for no limit |
getRows(int start, Integer maxRows, Consumer<String> status, Map<String,Object> extraParams)
Returns: RowsResult
Reads a page of rows, optionally taking extra parameters that a specific table implementation can use to filter its results. The default implementation ignores extraParams and reads from row zero rather than the given start; implementations that use extraParams override this method directly.
| Parameter | Description |
|---|---|
start | the zero based index of the first row to return; not used by the default implementation |
maxRows | the maximum number of rows to return, or null for no limit |
status | callback invoked with progress messages while the rows are being read |
extraParams | implementation specific filter parameters; not used by the default implementation |
supportsPagination()
Returns: boolean
Whether this table supports paged reads via the start and maxRows parameters of getRows. A table that returns false always returns its full result set regardless of the paging parameters supplied.
Methods
getTableId()
Returns: String
The table id, matching the id of the KCriteria builder this table runs and the key it is looked up under via QueryManager.getTable.
getDescription()
Returns: String
Description for this table. Always returns null, as criteria tables do not carry a separate description.
getHeaders()
Returns: List<String>
Column header labels, one per configured column, taken from each column's text.
getRows(int start, Integer maxRows, Consumer<String> status)
Returns: RowsResult
Runs the registered KCriteria builder matching this table's id with the given paging, then evaluates each configured column's property path against every result item, using MvelTemplater, to build the output rows.
| Parameter | Description |
|---|---|
start | the zero based index of the first row to return |
maxRows | the maximum number of rows to return, or null for no limit |
status | progress callback; not used by this implementation |
