Package java.io

Interface Summary

DataInput	Untamed: The DataInput interface provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types.
DataOutput	Untamed: The DataOutput interface provides for converting data from any of the Java primitive types to a series of bytes and writing these bytes to a binary stream.
Externalizable	Untamed: Only the identity of the class of an Externalizable instance is written in the serialization stream and it is the responsibility of the class to save and restore the contents of its instances.
FileFilter	Untamed:
FilenameFilter	Untamed:
ObjectInput	Untamed:
ObjectInputValidation	Untamed: Callback interface to allow validation of objects within a graph.
ObjectOutput	Untamed:
ObjectStreamConstants	Untamed: Constants written into the Object Serialization Stream.
Serializable	Untamed: Serializability of a class is enabled by the class implementing the java.io.Serializable interface.

Class Summary

Bits	Utility methods for packing/unpacking primitive values in/out of byte arrays using big-endian byte ordering.
BufferedInputStream	Untamed: A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods.
BufferedOutputStream	Untamed: The class implements a buffered output stream.
BufferedReader	Safe: Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
BufferedWriter	Untamed:
ByteArrayInputStream	Safe: A ByteArrayInputStream contains an internal buffer that contains bytes that may be read from the stream.
ByteArrayOutputStream	Safe:
CharArrayReader	Untamed: This class implements a character buffer that can be used as a character-input stream.
CharArrayWriter	Untamed: This class implements a character buffer that can be used as an Writer.
DataInputStream	Safe:
DataOutputStream	Safe:
File	Unsafe:
FileDescriptor	Untamed:
FileInputStream	Safe: A FileInputStream obtains input bytes from a file in a file system.
FileOutputStream	Safe: A file output stream is an output stream for writing data to a File or to a FileDescriptor.
FilePermission	Untamed: This class represents access to a file or directory.
FilePermissionCollection	A FilePermissionCollection stores a set of FilePermission permissions.
FileReader	Untamed: Convenience class for reading character files.
FileSystem
FileWriter	Untamed: Convenience class for writing character files.
FilterInputStream	Untamed: A FilterInputStream contains some other input stream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterOutputStream	Untamed: This class is the superclass of all classes that filter output streams.
FilterReader	Untamed: Abstract class for reading filtered character streams.
FilterWriter	Untamed: Abstract class for writing filtered character streams.
InputStream	Untamed: This abstract class is the superclass of all classes representing an input stream of bytes.
InputStreamReader	Safe: An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset.
LineNumberInputStream	Deprecated. This class incorrectly assumes that bytes adequately represent characters.
LineNumberReader	Untamed: A buffered character-input stream that keeps track of line numbers.
ObjectInputStream	Untamed:
ObjectOutputStream	Untamed: An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream.
ObjectStreamClass	Untamed: Serialization's descriptor for classes.
ObjectStreamField	Untamed:
OutputStream	Untamed: This abstract class is the superclass of all classes representing an output stream of bytes.
OutputStreamWriter	Untamed:
PipedInputStream	Untamed:
PipedOutputStream	Untamed: A piped output stream can be connected to a piped input stream to create a communications pipe.
PipedReader	Untamed:
PipedWriter	Untamed: Piped character-output streams.
PrintStream	Untamed:
PrintWriter	Untamed:
PushbackInputStream	Untamed:
PushbackReader	Untamed: A character-stream reader that allows characters to be pushed back into the stream.
RandomAccessFile	Safe: Instances of this class support both reading and writing to a random access file.
Reader	Untamed: Abstract class for reading character streams.
SequenceInputStream	Untamed: A SequenceInputStream represents the logical concatenation of other input streams.
SerializablePermission	Untamed:
StreamTokenizer	Untamed: The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time.
StringBufferInputStream	Deprecated. This class does not properly convert characters into bytes.
StringReader	Safe: A character stream whose source is a string.
StringWriter	Untamed: A character stream that collects its output in a string buffer, which can then be used to construct a string.
Win32FileSystem
WinNTFileSystem	Unicode-aware FileSystem for Windows NT/2000.
Writer	Untamed: Abstract class for writing to character streams.

Exception Summary

CharConversionException	Untamed: Base class for character conversion exceptions.
EOFException	Untamed: Signals that an end of file or end of stream has been reached unexpectedly during input.
FileNotFoundException	Untamed: Signals that an attempt to open the file denoted by a specified pathname has failed.
InterruptedIOException	Untamed: Signals that an I/O operation has been interrupted.
InvalidClassException	Untamed:
InvalidObjectException	Untamed: Indicates that one or more deserialized objects failed validation tests.
IOException	Untamed: Signals that an I/O exception of some sort has occurred.
NotActiveException	Untamed: Thrown when serialization or deserialization is not active.
NotSerializableException	Untamed: Thrown when an instance is required to have a Serializable interface.
ObjectStreamException	Untamed: Superclass of all exceptions specific to Object Stream classes.
OptionalDataException	Untamed: Exception indicating the failure of an object read operation due to unread primitive data, or the end of data belonging to a serialized object in the stream.
StreamCorruptedException	Untamed: Thrown when control information that was read from an object stream violates internal consistency checks.
