readFloat

public final float readFloat()
                      throws java.io.IOException

Reads a float from this file. This method reads an int value, starting at the current file pointer, as if by the readInt method and then converts that int to a float using the intBitsToFloat method in class Float.

This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown.

Specified by:

readFloat in interface java.io.DataInput

Returns:

the next four bytes of this file, interpreted as a float.

Throws:

java.io.EOFException - if this file reaches the end before reading four bytes.

java.io.IOException - if an I/O error occurs.

RandomAccessFile.readInt(), Float.intBitsToFloat(int)

readDouble

public final double readDouble()
                        throws java.io.IOException

Reads a double from this file. This method reads a long value, starting at the current file pointer, as if by the readLong method and then converts that long to a double using the longBitsToDouble method in class Double.

This method blocks until the eight bytes are read, the end of the stream is detected, or an exception is thrown.

Specified by:

readDouble in interface java.io.DataInput

Returns:

the next eight bytes of this file, interpreted as a double.

Throws:

java.io.EOFException - if this file reaches the end before reading eight bytes.

java.io.IOException - if an I/O error occurs.

RandomAccessFile.readLong(), Double.longBitsToDouble(long)

readChar

public char readChar()
              throws java.io.IOException

Specified by:

readChar in interface java.io.DataInput

Throws:

java.io.IOException

readByte

public byte readByte()
              throws java.io.IOException

Specified by:

readByte in interface java.io.DataInput

Throws:

java.io.IOException

seek

public void seek(long pos)
          throws java.io.IOException

Throws:
