Field Detail

targetTable

org.apache.derby.iapi.sql.execute.ExecCursorTableReference targetTable

This class implements Formatable. That means that it can write itself to and from a formatted stream. If you add more fields to this class, make sure that you also write/read them with the writeExternal()/readExternal() methods. If, inbetween releases, you add more fields to this class, then you should bump the version number emitted by the getTypeFormatId() method.

---

targetColumns

org.apache.derby.iapi.sql.ResultColumnDescriptor[] targetColumns

---

updateColumns

java.lang.String[] updateColumns

---

updateMode

int updateMode

Constructor Detail

CursorInfo

public CursorInfo()

Niladic constructor for Formatable

---

CursorInfo

public CursorInfo(int updateMode,
                  org.apache.derby.iapi.sql.execute.ExecCursorTableReference targetTable,
                  org.apache.derby.iapi.sql.ResultColumnDescriptor[] targetColumns,
                  java.lang.String[] updateColumns)

Method Detail

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Write this object out

Specified by:

writeExternal in interface java.io.Externalizable

---

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Read this object from a stream of stored objects.

Specified by:

readExternal in interface java.io.Externalizable

---

getTypeFormatId

public int getTypeFormatId()

Get the formatID which corresponds to this class.

Specified by:

getTypeFormatId in interface org.apache.derby.iapi.services.io.TypedFormat

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
