IteratorDataHolder

public IteratorDataHolder(Supplier<Iterator<DataEntry>> iteratorSupplier)

Method Details

asPrintableString

public String asPrintableString(boolean includeData)

Specified by:

asPrintableString in interface ImportDataHolder

hasNext

public boolean hasNext()

Description copied from interface: ImportDataHolder

Return true if a call to nextEntry will return more data. Returns false when all data has been read

Specified by:

hasNext in interface ImportDataHolder

nextEntry

public DataEntry nextEntry()

Description copied from interface: ImportDataHolder

Reads an object entry. Returns a list of strings that represents the data read from the external source. The list should contain all information required to create one object. I.e. all the relevant attributes represented by the data locators should be present. E.g. in the CSV file this will be one row in the file.

Specified by:

nextEntry in interface ImportDataHolder

Returns:

the next entry to be handled. Can return null to indicate that all data has been processed. An empty list will be treated as end of data and no more data will be read (the same as with null)

numberOfEntries

public int numberOfEntries()

Description copied from interface: ImportDataHolder

Returns the number of entries that this data holder contains

Specified by:

numberOfEntries in interface ImportDataHolder

dataToImport

public boolean dataToImport()

Description copied from interface: ImportDataHolder

Used to indicate if data exist to import. Notice that there is a difference between numberOfEntries != 0 and dataToImport = false. If dataToImport is false the handling of missing objects will be ignored but if the dataToImport is true and numberOfEntries = 0 all objects will be considered as missing objects and handled accordingly

Specified by:

dataToImport in interface ImportDataHolder

parsedResult

public ExternalDataParseResult parsedResult()

Description copied from interface: ImportDataHolder

Was all external data parsed? This is a way to inform the import that the data holder may not be complete. A way for the import module to indicate that something is wrong but the error is minor and the import can continue anyway

Specified by:

parsedResult in interface ImportDataHolder

Returns:

the ExternalDataParseResult
