Field Detail

dataDictionary

private transient org.apache.derby.iapi.sql.dictionary.DataDictionary dataDictionary

---

uuidFactory

private transient org.apache.derby.iapi.services.uuid.UUIDFactory uuidFactory

---

formatId

private final int formatId

Constructor Detail

DDdependableFinder

public DDdependableFinder(int formatId)

Public constructor for Formatable hoo-hah.

Method Detail

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()).

---

readExternal

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

Read this object from a stream of stored objects. Nothing to do. Our persistent representation is just a 2-byte format id.

Specified by:

readExternal in interface java.io.Externalizable

---

writeExternal

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

Write this object to a stream of stored objects. Again, nothing to do. We just stamp the output stream with our Format id.

Specified by:

writeExternal in interface java.io.Externalizable

---

getTypeFormatId

public final int getTypeFormatId()

Get the formatID which corresponds to this class.

Specified by:

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

---

getDependable

public final org.apache.derby.catalog.Dependable getDependable(java.lang.String dependableObjectID)
                                                        throws java.sql.SQLException

Gets the in-memory object associated with the passed-in object ID.

Specified by:

getDependable in interface org.apache.derby.catalog.DependableFinder

---

getDependable

public final org.apache.derby.catalog.Dependable getDependable(org.apache.derby.catalog.UUID dependableObjectID)
                                                        throws java.sql.SQLException

Gets the AliasDescriptor associated with the passed-in object ID.

Specified by:

getDependable in interface org.apache.derby.catalog.DependableFinder

                                        throws java.sql.SQLException

Description copied from interface: org.apache.derby.catalog.DependableFinder

Get the name of the SQL Object that corresponds to the specified UUID String. For example, if getSQLObjectType() returns "Table", this will return the table name.

Specified by:

getSQLObjectName in interface org.apache.derby.catalog.DependableFinder

---

getSQLObjectType

public java.lang.String getSQLObjectType()

Description copied from interface: org.apache.derby.catalog.DependableFinder

The name of the class of Dependables as a "SQL Object" which this Finder can find. This is a value like "Table", "View", or "Publication". Every DependableFinder can find some class of Dependables.

Specified by:

getSQLObjectType in interface org.apache.derby.catalog.DependableFinder

---

getDataDictionary

private org.apache.derby.iapi.sql.dictionary.DataDictionary getDataDictionary()
                                                                       throws org.apache.derby.iapi.error.StandardException
