Interface Summary
Interface	Description
ChecksumGenerator	Provide checksums over input.
Clock	Injectable clock to allow better testing.
InputStreamFactory	Interface for a factory for an `InputStream` to read a document.
UniqueIdGenerator	Interface for providers of a unique String ID.

Class Summary
Class	Description
Base16	Base16 encoder class.
Base64	Base64 converter class.
Base64ChecksumGenerator	An implementation of `ChecksumGenerator` that return Base64-encoded checksums using algorithms from `java.security.MessageDigest`.
Base64FilterInputStream	A `FilterInputStream` that Base64 encodes data read from an input stream.
BasicChecksumGenerator	An implementation of `ChecksumGenerator` that return hexadecimal-encoded checksums using algorithms from `java.security.MessageDigest`.
EmptyDocumentList	An empty document list that provides a new checkpoint.
EofFilterInputStream	This Filter protects against the poorly behaved Apache Commons IO `AutoCloseInputStream`, which can close a stream out from underneath us.
FileInputStreamFactory	An `InputStreamFactory` that manufactures `FileInputStreams`.
IOExceptionHelper	Deprecated Use `IOException.IOException(String, Throwable)`
MimeTypeDetector	Detector for MIME type based on file name and content.
SAXParseErrorHandler	A simple `ErrorHandler` implementation to be used with the the SAX Parser.
SslUtil	Utility methods for SSL.
SystemClock	`Clock` implementation that returns `System.currentTimeMillis()`.
TraversalTimer	A simple timer to control traversal loops and avoid batch timeouts.
UrlInputStreamFactory	An `InputStreamFactory` that manufactures URL `InputStream`.
UrlValidator	Validates URLs by making an HTTP request.
UuidGenerator	A `UniqueIdGenerator` implementation backed by `UUID`.
XmlParseUtil	Utility functions for parsing XML.
XmlParseUtil.LocalEntityResolver	An `EntityResolver` implementation that resolves entities using a selection of locally stored DTDs.
XmlParseUtil.ThrowingErrorHandler	A simple `ErrorHandler` implementation that always throws the `SAXParseException`.

Exception Summary
Exception	Description
Base64DecoderException	Exception thrown when encountering an invalid Base64 input character.
UrlValidatorException	Represents an invalid HTTP response during URL validation.

Package com.google.enterprise.connector.util Description

Defines utility classes that might be helpful for connector developers.

This package consists of concrete classes. Connector developers are not required to use the classes in this package. They are provided in case they are useful. In some cases, the connector manager may also use these classes.
