Method Details

createSchema

public void createSchema(MetaClass metaClass,
 Collection<MetaProperty> properties)

Description copied from interface: DynamicModelSchemaManager

Creates or updates the database schema for the given entity and its dynamic properties.

Specified by:

createSchema in interface DynamicModelSchemaManager

Parameters:

metaClass - the entity meta-class

properties - the dynamic properties to create columns for

createUniqueConstraints

public void createUniqueConstraints(MetaClass metaClass,
 Collection<DynamicUniqueConstraintDefinition> uniqueConstraints)

Description copied from interface: DynamicModelSchemaManager

Creates database unique constraints for the given entity.

Specified by:

createUniqueConstraints in interface DynamicModelSchemaManager

Parameters:

metaClass - owner metadata class

uniqueConstraints - normalized unique constraints

validateUniqueConstraintsData

public void validateUniqueConstraintsData(MetaClass metaClass,
 Collection<DynamicUniqueConstraintDefinition> uniqueConstraints)

Description copied from interface: DynamicModelSchemaManager

Verifies that existing table data satisfies the given unique constraints, throwing if duplicates exist. Used to fail before a destructive constraint replacement so the old constraint is preserved on failure.

Specified by:

validateUniqueConstraintsData in interface DynamicModelSchemaManager

Parameters:

metaClass - owner metadata class

uniqueConstraints - normalized unique constraints to validate against existing data

removeUniqueConstraints

public void removeUniqueConstraints(MetaClass metaClass,
 Collection<DynamicUniqueConstraintDefinition> uniqueConstraints)

Description copied from interface: DynamicModelSchemaManager

Removes database unique constraints for the given entity.

Specified by:

removeUniqueConstraints in interface DynamicModelSchemaManager

Parameters:

metaClass - owner metadata class

uniqueConstraints - normalized unique constraints

removeEntity

public void removeEntity(MetaClass metaClass)

Specified by:

removeEntity in interface DynamicModelSchemaManager

removeAttribute

public void removeAttribute(MetaClass metaClass,
 MetaProperty property)

Specified by:

removeAttribute in interface DynamicModelSchemaManager

alterColumn

public void alterColumn(MetaClass metaClass,
 MetaProperty property)

Description copied from interface: DynamicModelSchemaManager

Alters the physical column type/length of an existing dynamic attribute to match the given property.

Specified by:

alterColumn in interface DynamicModelSchemaManager

Parameters:

metaClass - the owning entity meta-class

property - the dynamic property whose column type changed

clear

public void clear()

Description copied from interface: DynamicModelSchemaManager

Removes all database objects created by this manager.

Specified by:

clear in interface DynamicModelSchemaManager

dropTable

public void dropTable(String tableName)

dropTable

public void dropTable(String storeName,
 String tableName)

dropColumn

public void dropColumn(String tableName,
 String columnName)

dropColumn

public void dropColumn(String storeName,
 String tableName,
 String columnName)

removeCollectionAttribute

protected void removeCollectionAttribute(MetaClass ownerMetaClass,
 MetaProperty property)
