Method Detail

iterator

public java.util.Iterator<org.ojai.Document> iterator()

Specified by:

iterator in interface java.lang.Iterable<org.ojai.Document>

Specified by:

iterator in interface org.ojai.DocumentStream

Overrides:

iterator in class AbstractDocumentFilter

closeDerived

protected void closeDerived()

Description copied from class: AbstractDocumentStream

Perform whatever steps the derived class requires for closing. Note that the object's lock/monitor will be held, as this is called by the final synchronized AbstractDocumentStream.close() method.
