Method Detail

readShort

public short readShort()
                throws java.io.IOException

Reads a signed 16-bit number as two bytes from the underlying input stream, low order byte first.

Specified by:

readShort in interface java.io.DataInput

Overrides:

readShort in class NativeDataInputStream

Returns:

the next two bytes of this input stream, interpreted as a signed 16-bit number.

Throws:

java.io.EOFException - if this input stream reaches the end before reading two bytes.

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

readUnsignedShort

public int readUnsignedShort()
                      throws java.io.IOException

Reads an unsigned 16-bit number as two bytes from the underlying input stream, low order byte first.

Specified by:

readUnsignedShort in interface java.io.DataInput

Overrides:

readUnsignedShort in class NativeDataInputStream

Returns:

the next two bytes of this input stream, interpreted as an unsigned 16-bit number.

Throws:

java.io.EOFException - if this input stream reaches the end before reading two bytes.

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

readChar

public char readChar()
              throws java.io.IOException

Reads a Unicode character as two bytes from the underlying input stream, low order byte first.

Specified by:

readChar in interface java.io.DataInput

Overrides:

readChar in class NativeDataInputStream

Returns:

the next two bytes of this input stream as a Unicode character.

Throws:

java.io.EOFException - if this input stream reaches the end before reading two bytes.

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

readInt

public int readInt()
            throws java.io.IOException

Reads a signed 32-bit integer from the underlying data input stream, low order byte first.

Specified by:

readInt in interface java.io.DataInput

Overrides:

readInt in class NativeDataInputStream

Returns:

the next four bytes of this input stream, interpreted as an int.

Throws:

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

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

readLong

public long readLong()
              throws java.io.IOException

Reads a signed 64-bit integer from the underlying data input stream, low order byte first.

Specified by:

readLong in interface java.io.DataInput

Overrides:

readLong in class NativeDataInputStream

Returns:

the next eight bytes of this input stream, interpreted as a long

Throws:

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

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