Method Detail

read

public int read()
         throws IOException

Overrides:

read in class FilterInputStream

Returns:

?

Throws:

IOException - ?

read

public final int read(byte[] abyte0)
               throws IOException

Overrides:

read in class FilterInputStream

Parameters:

abyte0 - ?

Returns:

?

Throws:

IOException - ?

read

public final int read(byte[] abyte0,
                      int i,
                      int j)
               throws IOException

Description copied from class: InputStream

Read byte data until there is no more available. This does not block for the balance of any data. If there is not data this returns -1. If there is some data but not all that is requested it returns what it has.

Overrides:

read in class FilterInputStream

Parameters:

abyte0 - ?

i - ?

j - ?

Returns:

?

Throws:

IOException - ?

readBoolean

public final boolean readBoolean()
                          throws IOException

Specified by:

readBoolean in interface DataInput

Returns:

?

Throws:

IOException - ?

readByte

public final byte readByte()
                    throws IOException

Specified by:

readByte in interface DataInput

Returns:

?

Throws:

IOException - ?

readChar

public final char readChar()
                    throws IOException

Specified by:

readChar in interface DataInput

Returns:

?

Throws:

IOException - ?

readDouble

public final double readDouble()
                        throws IOException

Specified by:

readDouble in interface DataInput

Returns:

?

Throws:

IOException - ?

readFloat

public final float readFloat()
                      throws IOException

Specified by:

readFloat in interface DataInput

Returns:

?

Throws:

IOException - ?

readFully

public final void readFully(byte[] arr)
                     throws IOException

reads the requested data. This blocks until the entire array is filled.

Specified by:

readFully in interface DataInput

Parameters:

arr - array to receive data

Throws:

IOException - if the stream is no longer available

readFully

public final void readFully(byte[] arr,
                            int ofs,

                     throws IOException

Reads the requested data. This blocks until all data received of the stream goes away.

Specified by:

readFully in interface DataInput

Parameters:

arr - byte array to receive data

ofs - offset into the array to receive data

len - total count to receive

Throws:

IOException - if the stream is no longer available
