Description copied from interface: LaggableMap

Gets the field value at the current position.

Specified by:

get in interface LaggableMap<String,Object>

Specified by:

get in interface Map<String,Object>

Overrides:

get in class AbstractMap<String,Object>

Parameters:

key - The field name.

Returns:

The field value or null.

getLagged

public Object getLagged(String key,
                        int n,
                        List<String> blockIndicatorKeys)

Description copied from interface: LaggableMap

Gets the field value after applying a "lag transformation" to the current position.

Specified by:

getLagged in interface LaggableMap<String,Object>

Parameters:

key - The field name.

n - The number of steps to move backwards from the current position. The previous position is 1 step backwards.

blockIndicatorKeys - Block indicator field names.

Returns:

The field value or null.

getAggregated

@IgnoreJRERequirement
public Object getAggregated(String key,
                            String function,
                            int n,
                            List<String> blockIndicatorKeys)

Description copied from interface: AggregableMap

Gets the aggregate field value after applying a "window transformation" to the current position.

Specified by:

getAggregated in interface AggregableMap<String,Object>

Parameters:

key - The field name.

function - The aggregation function name. The implementation should recognize and support all Lag.Aggregate enum constant values (except for the `none` value).

n - The window size.

blockIndicatorKeys - Block indicator field names.

Returns:

The aggregate field value.
