But many data sources, such as <A HREF="http://java.sun.com/javase/6/docs/api/java/io/Reader.html?is-external=true#read()" title="class or interface in java.io"><CODE>Reader.read()</CODE></A>), do not expose this information; the only way to 114 discover whether there is any data left is by trying to retrieve it. These 115 types of data sources are ordinarily difficult to write iterators for. But 116 using this class, one must implement only the <A HREF="../../../../com/google/common/collect/AbstractIterator.html#computeNext()"><CODE>computeNext()</CODE></A> method, 117 and invoke the <A HREF="../../../../com/google/common/collect/AbstractIterator.html#endOfData()"><CODE>endOfData()</CODE></A> method when appropriate. 118 119 <p>Another example is an iterator that skips over null elements in a backing 120 iterator. This could be implemented as: <pre> <code>public static Iterator<String> skipNulls(final Iterator<String> in) { 121 return new AbstractIterator<String>() { 122 protected String computeNext() { 123 while (in.hasNext()) { 124 String s = in.next(); 125 if (s != null) { 126 return s; 127 } 128 } 129 return endOfData(); 130 } 131 }; 132 }</code></pre> 133 134 This class supports iterators that
