ClassTableJDBCSeq

public ClassTableJDBCSeq()

Method Detail

getIgnoreUnmapped

public boolean getIgnoreUnmapped()

Whether unmapped classes should be ignored as possible primary key values in the table. Defaults to false.

setIgnoreUnmapped

public void setIgnoreUnmapped(boolean ignore)

Whether unmapped classes should be ignored as possible primary key values in the table. Defaults to false.

setIgnoreVirtual

public void setIgnoreVirtual(boolean ignore)

Deprecated. Use setIgnoreUnmapped(boolean). Retained for backwards-compatibility for auto-configuration.

getUseAliases

public boolean getUseAliases()

Whether to use type alises for primary key values in place of class names. Defaults to false.

setUseAliases

public void setUseAliases(boolean aliases)

Whether to use type alises for primary key values in place of class names. Defaults to false.

getStatus

protected TableJDBCSeq.Status getStatus(ClassMapping mapping)

Description copied from class: TableJDBCSeq

Return the appropriate status object for the given class, or null if cannot handle the given class. The mapping may be null.

Overrides:

getStatus in class TableJDBCSeq

addPrimaryKeyColumn

protected Column addPrimaryKeyColumn(Table table)

Description copied from class: TableJDBCSeq

Add the primary key column to the given table and return it.

Overrides:

addPrimaryKeyColumn in class TableJDBCSeq

getPrimaryKey

protected Object getPrimaryKey(ClassMapping mapping)

Description copied from class: TableJDBCSeq

Return the primary key value for the sequence table for the given class.

Overrides:

getPrimaryKey in class TableJDBCSeq

main

public static void main(String[] args)
                 throws Exception

Usage: java org.apache.openjpa.jdbc.kernel.ClassTableJDBCSeq [option]* -action/-a <add | drop | get | set> [class name | .java file | .class file | .jdo file] [value] Where the following options are recognized.

• -properties/-p <properties file or resource>: The path or resource name of a OpenJPA properties file containing information such as connection data as outlined in JDBCConfiguration. Optional.
• -<property name> <property value>: All bean properties of the OpenJPA JDBCConfiguration can be set by using their names and supplying a value.

The various actions are as follows.

• add: Create the sequence table.
• drop: Drop the sequence table.
• get: Print the current sequence value for the given class.
• set: Set the sequence value for the given class.

Throws:

Exception
