Constructor Detail

ConcatIterativeReader

public ConcatIterativeReader(IterativeReader<T>... readers)

Create an IterativeReader that iterates over the readers in readers

Parameters:

readers - the readers to combine into one IterativeReader

ConcatIterativeReader

public ConcatIterativeReader(Collection<IterativeReader<T>> inputs)

Create an IterativeReader that iterates over the readers in inputs

Parameters:

inputs - an iterator that contains the readers that are to be concatenated

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: IterativeReader

Returns true if the reader has more elements. (In other words, returns true if IterativeReader.next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface IterativeReader<T>

Returns:

true if the reader has more elements

next

public T next()
       throws IOException

Description copied from interface: IterativeReader

Returns the next element in the reader.

Specified by:

next in interface IterativeReader<T>

Returns:

the next element in the iteration

Throws:

IOException - if there is an io exception

close

public void close()
           throws IOException

Description copied from interface: IterativeReader

Closes the reader and releases any system resources associated with it. Once the reader has been closed, further hasNext() or next() invocations will throw an IOException. Closing a previously closed reader has no effect.

Specified by:

close in interface IterativeReader<T>

Throws:

IOException - If an I/O error occurs
