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 value 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

hasNonEmptyValue

boolean hasNonEmptyValue(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

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,
 String dataPath)
                throws SAXException,
IOException

Generates SAX events for the data at the given data path in the current DataHolder Do not generate any event if there is no values at the given path

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

IOException - if an error occurs while reading a value using the I/O API

dataToSAX

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

Generates SAX events for the data at the given data path in the current DataHolder Do not generate any event if there is no values at the given path

Parameters:

contentHandler - the ContentHandler that will receive the SAX events

dataPath - the path of the data to SAX

context - The context of the data to SAX

Throws:

SAXException - if an error occurs during the SAX events generation

IOException - if an error occurs while reading a value using the I/O API
