getQuickInfo

public String getQuickInfo()

Returns a quick info about the object, which can be displayed in the GUI.
Default implementation returns null.

Specified by:

getQuickInfo in interface QuickInfoSupporter

Returns:

null if no info available, otherwise short string

minNumMapsRequired

public abstract int minNumMapsRequired()

Returns the minimum number of maps that are required for the operation.

Returns:

the number of maps that are required, <= 0 means no lower limit

maxNumMapsRequired

public abstract int maxNumMapsRequired()

Returns the maximum number of maps that are required for the operation.

Returns:

the number of maps that are required, <= 0 means no upper limit

generates

public abstract Class generates()

The type of data that is generated.

Returns:

the class

check

protected void check(Map[] maps)

Checks the maps.

Default implementation only ensures that maps are present.

Parameters:

maps - the maps to check

doProcess

protected abstract O doProcess(Map[] maps,
                               MessageCollection errors)

Performs the actual processing of the maps.

Parameters:

maps - the containers to process

errors - for collecting errors

Returns:

the generated data

process

public O process(Map[] maps,
                 MessageCollection errors)

Processes the containers.

Parameters:

maps - the containers to process

errors - for collecting errors

Returns:

the generated data
