A straightforward implementation of {@link FSDirectory} using java.io.RandomAccessFile. However, this class has poor concurrent performance (multiple threads will bottleneck) as it synchronizes when multiple threads read from the same file. It's usually better to use {@link NIOFSDirectory} or {@link MMapDirectory} instead.

The SimpleFSDirectory..::..SimpleFSIndexOutput type exposes the following members.

Constructors

  NameDescription
Public methodSimpleFSDirectory..::..SimpleFSIndexOutput
Initializes a new instance of the SimpleFSDirectory..::..SimpleFSIndexOutput class

Methods

  NameDescription
Public methodClose (Overrides BufferedIndexOutput..::..Close()()()().)
Public methodCopyBytes
Copy numBytes bytes from input to ourself.
(Inherited from IndexOutput.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFlush
Forces any buffered output to be written.
(Inherited from BufferedIndexOutput.)
Public methodFlushBuffer
output methods:
(Overrides BufferedIndexOutput..::..FlushBuffer(array<Byte>[]()[][], Int32, Int32).)
Public methodGetFilePointer
Returns the current position in this file, where the next write will occur.
(Inherited from BufferedIndexOutput.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodLength (Overrides BufferedIndexOutput..::..Length()()()().)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodSeek
Random-access methods
(Overrides BufferedIndexOutput..::..Seek(Int64).)
Public methodSetLength (Overrides IndexOutput..::..SetLength(Int64).)
Public methodToString
Returns a String that represents the current Object.
(Inherited from Object.)
Public methodWriteByte
Writes a single byte.
(Inherited from BufferedIndexOutput.)
Public methodWriteBytes(array<Byte>[]()[][], Int32)
Writes an array of bytes.
(Inherited from IndexOutput.)
Public methodWriteBytes(array<Byte>[]()[][], Int32, Int32)
Writes an array of bytes.
(Inherited from BufferedIndexOutput.)
Public methodWriteChars(array<Char>[]()[][], Int32, Int32) Obsolete.
Writes a sub sequence of characters from char[] as the old format (modified UTF-8 encoded bytes).
(Inherited from IndexOutput.)
Public methodWriteChars(String, Int32, Int32) Obsolete.
Writes a sub sequence of characters from s as the old format (modified UTF-8 encoded bytes).
(Inherited from IndexOutput.)
Public methodWriteInt
Writes an int as four bytes.
