Examples of EofFilterInputStream

com.google.enterprise.connector.util.EofFilterInputStream
This Filter protects against the poorly behaved Apache Commons IO {@code AutoCloseInputStream}, which can close a stream out from underneath us. When that happens, reads while at EOF throw {@code IOException} ratherthan returning -1. This filter avoids calling {@code read()} on thesource stream once it is known to be at End-Of-File. @since 2.8
