Method Details

getComposite

Composite getComposite(String compositePath)
                throws IllegalArgumentException,
BadItemTypeException

Retrieves the composite at the given path

Parameters:

compositePath - path of the composite to retrieve

Returns:

the composite or null if not exists or is empty

Throws:

IllegalArgumentException - if the given composite path is null or empty

BadItemTypeException - if the stored value at the given path is not a composite

hasValue

boolean hasValue(String dataPath)
          throws IllegalArgumentException

Checks if there is a non empty value for the data at the given path

Parameters:

dataPath - path of the data

Returns:

true if there is a non empty value for the data, false otherwise

Throws:

IllegalArgumentException - if the given data path is null or empty

hasValueOrEmpty

boolean hasValueOrEmpty(String dataPath)
                 throws IllegalArgumentException

Checks if there is a value, even empty, for the data at the given path

Parameters:

dataPath - path of the data

Returns:

true if there is value, even empty, for the data, false otherwise

Throws:

IllegalArgumentException - if the given data path is null or empty

getDataNames

Collection<String> getDataNames()

Retrieves the names of data contained by this data holder Retrieves only the data at first level, does not check composite data

Returns:

the names of all data contained by this data holder

copyTo

default void copyTo(ModifiableDataHolder dataHolder)
             throws UndefinedItemPathException,
BadItemTypeException,
UnknownTypeException,
NotUniqueTypeException

Copies the current DataHolder to the given ModifiableModelAwareDataHolder.

Parameters:

dataHolder - The destination dataHolder. Can not be null.

Throws:

UndefinedItemPathException - if one of the copied data is not defined by the model of the destination ModifiableModelAwareDataHolder

BadItemTypeException - if the type defined by the model of the destination ModifiableModelAwareDataHolder doesn't match the copied value

UnknownTypeException - if there is no available type compatible with the copied value for the type extension point of the destination ModifiableModelLessDataHolder

NotUniqueTypeException - if there is more than one available types compatibles with the copied value for the type extension point of the destination ModifiableModelLessDataHolder

dataToSAX

default void dataToSAX(ContentHandler contentHandler,

Parameters:

contentHandler - the ContentHandler that will receive the SAX events

dataPath - the path of the data to SAX

Throws:

SAXException - if an error occurs during the SAX events generation

dataToSAX

void dataToSAX(ContentHandler contentHandler,
 String dataPath,
 DataContext context)
        throws SAXException
