Returns:

staticpreprocessor

public void staticpreprocessor(java.lang.String next)

Overrides:

staticpreprocessor in class FlatFileLoaderColumn<E extends DataObject<E> & UniqueidentifiedInterface<E>>

load

public boolean load(E object,
                    java.lang.Object value,
                    PostUpdateProcessingStore<E> postupdateprocessingstore)

performs the load

Specified by:

load in class FlatFileLoaderColumn<E extends DataObject<E> & UniqueidentifiedInterface<E>>

Parameters:

object - the object on which to load data

value - an object, either Date, String or Double

postupdateprocessingstore - a store to perform post processing after the single update

Returns:

true if something was changed on the object, else, false

isLinePreparatorExtra

public boolean isLinePreparatorExtra()

Overrides:

isLinePreparatorExtra in class FlatFileLoaderColumn<E extends DataObject<E> & UniqueidentifiedInterface<E>>

Returns:

true if the line is a preparator extra. Then, the loader column will have to implement (overrides) the method generateLinePreparatorExtra

Specified by:

putContentInCell in class FlatFileLoaderColumn<E extends DataObject<E> & UniqueidentifiedInterface<E>>

Parameters:

currentobject - the object to analyze

cell - cell to put the data in

context - a context in case of multiple lines per same object

Returns:

true if specific style was applied, false if specific style was not applied
