Method Detail

getPath

java.lang.String getPath()

Gets the path of this instance of the column.

Returns:

The path of this column (for example "/etc/reports/areport/jcr:content/report/col1")

getName

java.lang.String getName()

Gets the name of this instance of the column.

Returns:

The name of this column (usually last part of the column's path)

getTitle

java.lang.String getTitle()

Gets the title of this instance of the column.

Returns:

The title of the column

getColumnType

java.lang.String getColumnType()

Returns the column's data type.

Returns:

The column's data type

getActualType

java.lang.String getActualType()

Returns the column's actual type for the current report setting.

Contrary to getColumnType(), this method considers aggregation state.

The returned value must be supported by the clientside reporting implementation. See DisplayDataType for a list of officially supported display types. Note that there might be more supported types (which is why a String is returned rather than a DisplayDataType).

Returns:

The actual type

getColumnDef

QueryEngineConfig getColumnDef()

Get the query engine-specific column definitions.

Returns:

The query engine-specific definition

isGrouped

boolean isGrouped()

Checks if the column is currently grouped.

Returns:

true if the column is grouped

getAggregateType

java.lang.String getAggregateType()

Returns the aggregate type defined for the column.

Returns:

The aggregate type defined for the column

getSorting

Sorting getSorting()

Returns the sorting defined for the column.

Returns:

The sorting defined for the column

startProcessing

void startProcessing()

Starts the postprocessing of data.

endProcessing

void endProcessing()

Ends the postprocessing of data.

preprocessData

CellValue preprocessData(ProcessingPhase type,
                         DataRow row,
                         boolean isAggregated,
                         boolean isReportGrouped)

Preprocesses the specified data row.

If required by the type parameter (for example for ProcessingPhase.APPLY), the preprocessed data gets changed in the DataRow specified.

Parameters:

type - Type of preprocessing to be executed

row - The row to be preprocessed

isAggregated - true if the preprocessing is executed for the aggregated column value (if the column actually represents an aggregated value)

isReportGrouped - true if the report as a whole is grouped

Returns:

The preprocessed data

resolve

void resolve(Session session,
             DataRow rowToResolve)
      throws RepositoryException

Resolves the column's value in the specified row if applicable.

The resolved value must be set in the row.

Parameters:

session - JCR Session used for resolving

rowToResolve - The row

Throws:

RepositoryException - if resolving the value has failed due to a repository problem

matchesFilter

boolean matchesFilter(FilteringPhase phase,
                      DataRow rowToCheck)

Checks if the specified DataRow matches the current filter settings

Parameters:

phase - The current filtering phase

rowToCheck - The row to be checked against the filter

Returns:

true if the row matches the filter and should be kept in the result set

cleanup

void cleanup()

Cleans up the column after using it.
