Class DelegateDDLGenerator

java.lang.Object
oracle.javatools.db.extension.DelegateDDLGenerator

All Implemented Interfaces:

DDLGenerator, PropertyManager

public final class DelegateDDLGenerator

extends java.lang.Object

implements DDLGenerator

DDLGenerator implementation that delegates to another DDLGenerator for all normal object types. For any object type registered through the DBObjectRegistry the calls are instead delegated to the appropriately registered DDLGenerator implementation there instead.

Since:

11.1.1.4.0

Constructor Summary

DelegateDDLGenerator(DDLGenerator base, DatabaseDescriptor desc, DBObjectProvider pro)

Method Summary

boolean	canAlterProperty(DBObject original, DBObject update, java.lang.String prop) Convenience method to call PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) and check the return value is a PropertyAction with a type of ALTER.
PropertyAction	canChangeProperty(DBObject original, DBObject update, java.lang.String prop) Queries the support for setting or changing the given property for a create or update.
PropertyAction	canUpdateObject(DBObject original, DBObject update) Convenience method that uses PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) on all the differences in the given object to tell whether the update on the given objects can be done using a CREATE, ALTER or REPLACE as appropriate.
PropertyAction	canUpdateObject(Difference diff) Convenience method that uses PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) on all the differences in the given Difference to tell whether the update on the given objects can be done using a CREATE, ALTER or REPLACE as appropriate.
DDL	getCreateDDL(DDLOptions options, DBObject... objects) Gets CREATE statements for the given objects.
DDL	getDeleteDDL(DDLOptions options, DBObject... objects) Gets DROP statements for the given objects.
DDL	getUndeleteDDL(DDLOptions options, DBObject... objects) Gets statements to undelete (e.g.
DDL	getUpdateDDL(DDLOptions options, Difference diff) Gets ALTER statements for the given objects where possible, or DROP/CREATE, or CREATE AND REPLACE where appropriate/necessary.
boolean	supportsAction(java.lang.String type, PropertyAction.Type action) Asks whether a given action is supported for the specified object type in this provider.
boolean	supportsProperty(java.lang.String type, java.lang.String prop) Tests whether the given property is supported for the given object type.

DelegateDDLGenerator

public DelegateDDLGenerator(DDLGenerator base,
                            DatabaseDescriptor desc,
                            DBObjectProvider pro)

Method Detail

canAlterProperty

public boolean canAlterProperty(DBObject original,
                                DBObject update,
                                java.lang.String prop)

Description copied from interface: PropertyManager

Convenience method to call PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) and check the return value is a PropertyAction with a type of ALTER.

Specified by:

canAlterProperty in interface PropertyManager

Parameters:

original - the original object (null for a create query)

update - the updated (or new) object

prop - the property name / path to query

Returns:

true if the given property can be changed using ALTER.

canChangeProperty

public PropertyAction canChangeProperty(DBObject original,
                                        DBObject update,
                                        java.lang.String prop)

Description copied from interface: PropertyManager

Queries the support for setting or changing the given property for a create or update. If the original object is null then the request is to test whether the given property is settable on a new object. If the original object is not null the request is to test whether the given property can be changed, and if so whether the change can be applied by an update/alter or whether a replace/recreate is needed.

Specified by:

canChangeProperty in interface PropertyManager

Parameters:

original - the original object (null for a create query)

update - the updated (or new) object

prop - the property name / path to query

Returns:

an appropriate property action indicating the level of support for that property if supported, or null if the property is not supported.

canUpdateObject

public PropertyAction canUpdateObject(DBObject original,
                                      DBObject update)

Description copied from interface: PropertyManager

Convenience method that uses PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) on all the differences in the given object to tell whether the update on the given objects can be done using a CREATE, ALTER or REPLACE as appropriate.

Specified by:

canUpdateObject in interface PropertyManager

Parameters:

original - the original object (null for a create query)

update - the updated (or new) object

Returns:

an appropriate property action indicating the level support if the update is supported, or null if the update is not supported.

canUpdateObject

public PropertyAction canUpdateObject(Difference diff)

Description copied from interface: PropertyManager

Convenience method that uses PropertyManager.canChangeProperty(oracle.javatools.db.DBObject, oracle.javatools.db.DBObject, java.lang.String) on all the differences in the given Difference to tell whether the update on the given objects can be done using a CREATE, ALTER or REPLACE as appropriate.

Specified by:

canUpdateObject in interface PropertyManager

Parameters:

diff - the changes to test

Returns:

an appropriate property action indicating the level support if the update is supported, or null if the update is not supported.
