Class ClobType

java.lang.Object

org.teiid.core.types.Streamable<Clob>

org.teiid.core.types.ClobType

All Implemented Interfaces:

Externalizable, Serializable, Comparable<ClobType>, Clob, NClob, Sequencable

public final class ClobType
extends Streamable<Clob>
implements NClob, Sequencable, Comparable<ClobType>

This is wrapper on top of a "clob" object, which implements the "java.sql.Clob" interface. This class also implements the Streamable interface

Utility method to convert to String

Parameters:

clob -

Returns:

string form of the clob passed.

Throws:

SQLException

IOException

public CharSequence getCharSequence()

Specified by:

getCharSequence in interface Sequencable

free

public void free()
          throws SQLException

Specified by:

free in interface Clob

Throws:

SQLException

getCharacterStream

public Reader getCharacterStream(long pos,
                                 long len)
                          throws SQLException

writeReference

protected void writeReference(DataOutput out)
                       throws IOException

Since we have the length in chars we'll just write out in double byte format. These clobs should be small, so the wasted space should be minimal.

Specified by:

compareTo in interface Comparable<ClobType>

equals

public boolean equals(Object obj)
