Constructor Detail

• IndexInput

  @Deprecated
  protected IndexInput()

  Deprecated.

  please pass resourceDescription

• IndexInput

  protected IndexInput​(String resourceDescription)

  resourceDescription should be a non-null, opaque string describing this resource; it's returned from toString().

Method Detail

• skipChars

  @Deprecated
  public void skipChars​(int length)
                 throws IOException

  Deprecated.

  this method operates on old "modified utf8" encoded strings
  Expert Similar to DataInput.readChars(char[], int, int) but does not do any conversion operations on the bytes it is reading in. It still has to invoke DataInput.readByte() just as DataInput.readChars(char[], int, int) does, but it does not need a buffer to store anything and it does not have to do any of the bitwise operations, since we don't actually care what is in the byte except to determine how many more bytes to read

  Parameters:

  length - The number of chars to read

  Throws:

  IOException

• close

  public abstract void close()
                      throws IOException

  Closes the stream to further operations.

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable

  Throws:

  IOException

• getFilePointer

  public abstract long getFilePointer()

  Returns the current position in this file, where the next read will occur.

  seek(long)

• seek

  public abstract void seek​(long pos)
                     throws IOException

  Sets current position in this file, where the next read will occur.

  Throws:

  IOException

  See Also:

  getFilePointer()

• length

  public abstract long length()

  The number of bytes in the file.

• copyBytes

  public void copyBytes​(IndexOutput out,
                        long numBytes)
                 throws IOException

  Copies numBytes bytes to the given IndexOutput.

  NOTE: this method uses an intermediate buffer to copy the bytes. Consider overriding it in your implementation, if you can make a better, optimized copy.

  NOTE ensure that there are enough bytes in the input to copy to output. Otherwise, different exceptions may be thrown, depending on the implementation.

  Throws:

  IOException

• toString

  public String toString()

  Overrides:

  toString in class Object
