java.lang.Object
java.io.InputStream
oracle.xdb.RealInputStream

All Implemented Interfaces:

java.io.Closeable

public class RealInputStream

extends java.io.InputStream

Class that provides an inputstream abstraction to support reading from an underlying oracle stream.

Field Summary

static int	KGHSSTREAM Constant to denote a kghsstream.
static int	OCISTREAM Constant to denote an ocistream.

Constructor Summary

RealInputStream(long c_errhp, long c_state)
Public constructor.

RealInputStream(long c_errhp, long c_state, int m_type, long m_gp)
Public constructor.

Method Summary

void	close() Function to close the RealInputStream
boolean	markSupported() Function to check if "mark" and "reset" are supported
int	read() Function to read the next byte of data
int	read(byte[] b) Function to read upto b.length bytes of data into a byte array
int	read(byte[] b, int off, int len) Function to read upto "len" bytes of data into a byte array

RealInputStream

public RealInputStream(long c_errhp,
                       long c_state,
                       int m_type,
                       long m_gp)

Public constructor.

Parameters:

c_errhp - Pointer to the C error handler.

c_state - Pointer to the corresponding C state.

m_type - The stream type.

m_gp - Pointer to the generic PGA.

Method Detail

read

public int read(byte[] b)

Function to read upto b.length bytes of data into a byte array

Overrides:

read in class java.io.InputStream

Parameters:

b - The byte array to read into

Returns:

The total number of bytes read into the buffer (-1) if the end of the stream is reached

read

public int read()

Function to read the next byte of data

Specified by:

read in class java.io.InputStream

Returns:

The next byte of data (-1) if the end of the stream is reached

markSupported

public boolean markSupported()

Function to check if "mark" and "reset" are supported

Overrides:

markSupported in class java.io.InputStream

Returns:

FALSE indicating that these operations are not supported

read

public int read(byte[] b,
                int off,
                int len)

Function to read upto "len" bytes of data into a byte array

Overrides:

read in class java.io.InputStream

Parameters:

b - The byte array to read into

off - Start offset of the data

len - The maximum number of bytes to read

Returns:

The total number of bytes read into the buffer (-1) if the end of the stream is reached

close

public void close()

Function to close the RealInputStream

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.InputStream
