QueueInputStream
Simple alternative to JDK
PipedInputStream ; queue input stream provides what's written in queue output stream. |
Class and 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.
|
AutoCloseInputStream.Builder
Builds a new
AutoCloseInputStream instance. |
BOMInputStream
This class is used to wrap a stream that includes an encoded
ByteOrderMark as its first bytes. |
BOMInputStream.Builder
Builds a new
BOMInputStream instance. |
BrokenInputStream
Always throws an
IOException from all the InputStream methods where the exception is declared. |
BrokenReader
Always throws an
IOException from all the Reader methods where the exception is declared. |
BufferedFileChannelInputStream
InputStream implementation which uses direct buffer to read a file to avoid extra copy of data between Java and native memory which happens when
using BufferedInputStream . |
BufferedFileChannelInputStream.Builder
Builds a new
BufferedFileChannelInputStream instance. |
ByteBufferCleaner.Cleaner |
CharSequenceInputStream
Implements an
InputStream to read from String, StringBuffer, StringBuilder or CharBuffer. |
CharSequenceInputStream.Builder
Builds a new
CharSequenceInputStream instance. |
CircularInputStream
An
InputStream that repeats provided bytes for given target byte count. |
ClosedInputStream
Always returns
IOUtils.EOF to all attempts to read something from the stream. |
ClosedReader
Always returns
IOUtils.EOF to all attempts to read something from it. |
CloseShieldInputStream
Proxy stream that prevents the underlying input stream from being closed.
|
CloseShieldReader
Proxy reader that prevents the underlying reader from being closed.
|
MemoryMappedFileInputStream
An
InputStream that utilizes memory mapped files to improve performance. |
MemoryMappedFileInputStream.Builder
Builds a new
MemoryMappedFileInputStream instance. |
MessageDigestCalculatingInputStream
Deprecated.
|
MessageDigestCalculatingInputStream.Builder
Deprecated.
Builds a new
MessageDigestCalculatingInputStream instance. |
MessageDigestInputStream
This class is an example for using an
ObservableInputStream . |
MessageDigestInputStream.Builder
Builds new
MessageDigestInputStream instances. |
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
ObservableInputStream s. |
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.
|
QueueInputStream
Simple alternative to JDK
PipedInputStream ; queue input stream provides what's written in queue output stream. |
QueueInputStream.Builder
Builds a new
QueueInputStream instance. |
RandomAccessFileInputStream
Streams data from a
RandomAccessFile starting at its current position. |
RandomAccessFileInputStream.Builder
Builds a new
RandomAccessFileInputStream instance. |
ReadAheadInputStream
Implements
InputStream to asynchronously read ahead from an underlying input stream when a specified amount of data has been read from the current
buffer. |
ReadAheadInputStream.Builder
Builds a new
ReadAheadInputStream instance. |
ReaderInputStream
InputStream implementation that reads a character stream from a Reader and transforms it to a byte stream using a specified charset encoding. |
ReaderInputStream.Builder
Builds a new
ReaderInputStream instance. |
ReversedLinesFileReader
Reads lines in a file reversely (similar to a BufferedReader, but starting at the last line).
|
ReversedLinesFileReader.Builder
Builds a new
ReversedLinesFileReader instance. |
ReversedLinesFileReader.FilePart |
Tailer
Simple implementation of the UNIX "tail -f" functionality.
|
Tailer.Builder
Builds a
Tailer with default values. |
Tailer.RandomAccessResourceBridge
Bridges access to a resource for random access, normally a file.
|
Tailer.Tailable
A tailable resource like a file.
|
TailerListener
Listener for events from a
Tailer . |
UncheckedBufferedReader
A
BufferedReader that throws UncheckedIOException instead of IOException . |
UncheckedBufferedReader.Builder
Builds a new
UncheckedBufferedReader instance. |
UncheckedFilterInputStream
A
BufferedReader that throws UncheckedIOException instead of IOException . |
UncheckedFilterInputStream.Builder
Builds a new
UncheckedFilterInputStream instance. |
UncheckedFilterReader
A
FilterReader that throws UncheckedIOException instead of IOException . |
UncheckedFilterReader.Builder
Builds a new
UncheckedFilterReader instance. |
UnsynchronizedBufferedInputStream
An unsynchronized version of
BufferedInputStream , not thread-safe. |
UnsynchronizedByteArrayInputStream
This is an alternative to
ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is
not thread-safe. |
UnsynchronizedByteArrayInputStream.Builder
Builds a new
UnsynchronizedByteArrayInputStream instance. |
UnsynchronizedFilterInputStream
An unsynchronized version of
FilterInputStream , not thread-safe. |
UnsynchronizedFilterInputStream.Builder
Builds a new
UnsynchronizedFilterInputStream instance. |
XmlStreamReader
Character stream that handles all the necessary Voodoo to figure out the charset encoding of the XML document within the stream.
|
XmlStreamReader.Builder
Builds a new
XmlStreamWriter instance. |
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.
