Class ClassMappingInfo

java.lang.Object
  org.apache.openjpa.jdbc.meta.MappingInfo
      org.apache.openjpa.jdbc.meta.ClassMappingInfo

All Implemented Interfaces:

Serializable, SourceTracker, Commentable

public class ClassMappingInfo
extends MappingInfo
implements SourceTracker, Commentable

Information about the mapping from a class to the schema, in raw form. The columns and tables used in mapping info will not be part of the SchemaGroup used at runtime. Rather, they will be structs with the relevant pieces of information filled in.

public ClassMappingInfo()

Method Detail

getClassName

public String getClassName()

The described class name.

setClassName

public void setClassName(String name)

The described class name.

getHierarchyStrategy

public String getHierarchyStrategy()

The default strategy for subclasses in this hierarchy.

setHierarchyStrategy

public void setHierarchyStrategy(String strategy)

The default strategy for subclasses in this hierarchy.

getTableName

public String getTableName()

The given table name.

setTableName

public void setTableName(String table)

The given table name.

getSchemaName

public String getSchemaName()

The default schema name for unqualified tables.

setSchemaName

public void setSchemaName(String schema)

The default schema name for unqualified tables.

isJoinedSubclass

public boolean isJoinedSubclass()

Whether there is a join to the superclass table.

setJoinedSubclass

public void setJoinedSubclass(boolean joined)

Whether there is a join to the superclass table.

getSecondaryTableNames

public String[] getSecondaryTableNames()

Return the class-level joined tables.

getSecondaryTableName

public String getSecondaryTableName(String tableName)

We allow fields to reference class-level joins using just the table name, whereas the class join might have schema, etc information. This method returns the name of the given table as listed in a class-level join, or the given name if no join exists.

getSecondaryTableJoinColumns

public List getSecondaryTableJoinColumns(String tableName)

Return any columns defined for the given class level join, or empty list if none.

setSecondaryTableJoinColumns

public void setSecondaryTableJoinColumns(String tableName,
                                         List cols)

Declare the given class-level join.

getTable

public Table getTable(ClassMapping cls,
                      boolean adapt)

Return the table for the given class.

getDataStoreIdColumns

public Column[] getDataStoreIdColumns(ClassMapping cls,
                                      Column[] tmplates,
                                      Table table,
                                      boolean adapt)

Return the datastore identity columns for the given class, based on the given templates.

getSuperclassJoin

public ForeignKey getSuperclassJoin(ClassMapping cls,
                                    Table table,
                                    boolean adapt)

Return the join from this class to its superclass. The table for this class must be set.

syncWith

public void syncWith(ClassMapping cls)

Synchronize internal information with the mapping data for the given class.
