Method Summary

int	available() Deprecated Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
void	close() Deprecated Close input stream, close connection, and end transaction
long	getBlobSize() Deprecated Returns the size of the blob if available.
void	mark(int readLimit) Deprecated Marks the current position in this input stream.
boolean	markSupported() Deprecated Tests if this input stream supports the mark and reset methods.
int	read() Deprecated Reads the next byte of data from the input stream.
int	read(byte[] b) Deprecated Reads some number of bytes from the input stream and stores them into the buffer array b.
int	read(byte[] b, int off, int len) Deprecated Reads up to len bytes of data from the input stream into an array of bytes.
void	reset() Deprecated Repositions this stream to the position at the time the mark method was last called on this input stream.
long	skip(long n) Deprecated Skips over and discards n bytes of data from this input stream.

Constructor Detail

CM_InputStream

public CM_InputStream(String dataSourceName,
                      String propertyName,
                      int nodeId)

Deprecated

Constructs an inputstream for a given property and node.

Parameters

dataSourceName - The name of the datasource which represents the tables where the CM tables exist.

propertyName - The name of the property

nodeId - The node id

CM_InputStream

public CM_InputStream(String dataSourceName,
                      String propertyName,
                      Long propertyId,
                      int nodeId)

Deprecated

Constructs an inputstream for a given property and node.

Parameters

dataSourceName - The name of the datasource which represents the tables where the CM tables exist.

propertyName - The name of the property

propertyId - The id of the property

nodeId - The node id

CM_InputStream

public CM_InputStream(String propertyName,
                      int nodeId)

Deprecated

Constructs an inputstream for a given property and node. Uses the "contentDataSource".

Parameters

propertyName - The name of the property

nodeId - The node id

Method Detail

getBlobSize

public long getBlobSize()

Deprecated

Returns the size of the blob if available.

Overrides:

getBlobSize in class com.bea.content.internal.client.common.CM_InputStream

Returns

The blob size.

markSupported

public boolean markSupported()

Deprecated

Tests if this input stream supports the mark and reset methods. Whether or not mark and reset are supported is an invariant property of a particular input stream instance. The markSupported method of InputStream returns false.

Overrides:

markSupported in class com.bea.content.internal.client.common.CM_InputStream

Returns

true if this stream instance supports the mark and reset methods; false otherwise.

mark

public void mark(int readLimit)

Deprecated

Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.

The readlimit arguments tells this input stream to allow that many bytes to be read before the mark position gets invalidated.

The general contract of mark is that, if the method markSupported returns true, the stream somehow remembers all the bytes read after the call to mark and stands ready to supply those same bytes again if and whenever the method reset is called. However, the stream is not required to remember any data at all if more than readlimit bytes are read from the stream before reset is called.

The mark method of InputStream does nothing.

Overrides:

mark in class com.bea.content.internal.client.common.CM_InputStream

Parameters

readLimit - the maximum limit of bytes that can be read before the mark position becomes invalid.

reset

public void reset()
           throws IOException

Deprecated

Repositions this stream to the position at the time the mark method was last called on this input stream.

Overrides:

reset in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

skip

public long skip(long n)
          throws IOException

Deprecated

Skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. This may result from any of a number of conditions; reaching end of file before n bytes have been skipped is only one possibility. The actual number of bytes skipped is returned. If n is negative, no bytes are skipped.

Overrides:

skip in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

available

public int available()
              throws IOException

Deprecated

Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. Honors the underlying database implementation.

Overrides:

available in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

read

public int read()
         throws IOException

Deprecated

Reads the next byte of data from the input stream.

Overrides:

read in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

read

public int read(byte[] b)
         throws IOException

Deprecated

Reads some number of bytes from the input stream and stores them into the buffer array b.

Overrides:

read in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

read

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

Deprecated

Reads up to len bytes of data from the input stream into an array of bytes.

Overrides:

read in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException

close

public void close()
           throws IOException

Deprecated

Close input stream, close connection, and end transaction

Specified by:

close in interface Closeable

Overrides:

close in class com.bea.content.internal.client.common.CM_InputStream

Throws

IOException
