Package org.teiid.core.types

Class BaseClobType

java.lang.Object

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

org.teiid.core.types.BaseClobType

All Implemented Interfaces:

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

Direct Known Subclasses:

ClobType, JsonType

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

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

Specified by:

readReference in class Streamable<Clob>

Throws:

IOException

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:

writeReference in class Streamable<Clob>

Throws:

IOException

compareTo

public int compareTo(BaseClobType o)

Specified by:

compareTo in interface Comparable<BaseClobType>

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
