Package org.apache.commons.io.input

This package provides implementations of input classes, such as InputStream and Reader.

Interface Summary

Interface	Description
TailerListener	Listener for events from a Tailer.

Class Summary

Class	Description
AbstractCharacterFilterReader	A filter reader that filters out characters where subclasses decide which characters to filter out.
AutoCloseInputStream	Proxy stream that closes and discards the underlying stream as soon as the end of input has been reached or when the stream is explicitly closed.
BOMInputStream	This class is used to wrap a stream that includes an encoded ByteOrderMark as its first bytes.
BoundedInputStream	This is a stream that will only supply bytes up to a certain length - if its position goes above that, it will stop.
BoundedReader	A reader that imposes a limit to the number of characters that can be read from an underlying reader, returning EOF when this limit is reached, regardless of state of underlying reader.
BrokenInputStream	Broken input stream.
BrokenReader	Broken reader.
CharacterFilterReader	A filter reader that filters out a given character represented as an int code point, handy to remove known junk characters from CSV files for example.
CharacterSetFilterReader	A filter reader that removes a given set of characters represented as int code points, handy to remove known junk characters from CSV files for example.
CharSequenceInputStream	InputStream implementation that can read from String, StringBuffer, StringBuilder or CharBuffer.
CharSequenceReader	Reader implementation that can read from String, StringBuffer, StringBuilder or CharBuffer.
CircularInputStream	An InputStream that repeats provided bytes for given target byte count.
ClassLoaderObjectInputStream	A special ObjectInputStream that loads a class based on a specified ClassLoader rather than the system default.
ClosedInputStream	Closed input stream.
ClosedReader	Closed reader.
CloseShieldInputStream	Proxy stream that prevents the underlying input stream from being closed.
CloseShieldReader	Proxy stream that prevents the underlying reader from being closed.
CountingInputStream	A decorating input stream that counts the number of bytes that have passed through the stream so far.
DemuxInputStream	Data written to this stream is forwarded to a stream that has been associated with this thread.
InfiniteCircularInputStream	An InputStream that infinitely repeats the provided bytes.
MarkShieldInputStream	This is an alternative to ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe.
MessageDigestCalculatingInputStream	This class is an example for using an ObservableInputStream.
MessageDigestCalculatingInputStream.MessageDigestMaintainingObserver	Maintains the message digest.
NullInputStream	A functional, light weight InputStream that emulates a stream of a specified size.
NullReader	A functional, light weight Reader that emulates a reader of a specified size.
ObservableInputStream	The ObservableInputStream allows, that an InputStream may be consumed by other receivers, apart from the thread, which is reading it.
ObservableInputStream.Observer	Abstracts observer callback for ObservableInputStreams.
ProxyInputStream	A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
ProxyReader	A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
RandomAccessFileInputStream	Streams data from a RandomAccessFile starting at its current position.
ReaderInputStream	InputStream implementation that reads a character stream from a Reader and transforms it to a byte stream using a specified charset encoding.
ReversedLinesFileReader	Reads lines in a file reversely (similar to a BufferedReader, but starting at the last line).
SequenceReader	Provides the contents of multiple Readers in sequence.
SwappedDataInputStream	DataInput for systems relying on little endian data formats.
TaggedInputStream	An input stream decorator that tags potential exceptions so that the stream that caused the exception can easily be identified.
TaggedReader	A reader decorator that tags potential exceptions so that the reader that caused the exception can easily be identified.
Tailer	Simple implementation of the unix "tail -f" functionality.
TailerListenerAdapter	TailerListener Adapter.
TeeInputStream	InputStream proxy that transparently writes a copy of all bytes read from the proxied stream to a given OutputStream.
TeeReader	Reader proxy that transparently writes a copy of all characters read from the proxied reader to a given Reader.
UnixLineEndingInputStream	A filtering input stream that ensures the content will have unix-style line endings, LF.
UnsynchronizedByteArrayInputStream	This is an alternative to ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe.
WindowsLineEndingInputStream	A filtering input stream that ensures the content will have windows line endings, CRLF.
XmlStreamReader	Character stream that handles all the necessary Voodoo to figure out the charset encoding of the XML document within the stream.

Exception Summary

Exception	Description
XmlStreamReaderException	The XmlStreamReaderException is thrown by the XmlStreamReader constructors if the charset encoding can not be determined according to the XML 1.0 specification and RFC 3023.
