isAbstract
public boolean isAbstract()
- Is this an abstract class?
- Specified by:
isAbstract in interface Loadable
isExplicitPolymorphism
public boolean isExplicitPolymorphism()
- Is this class explicit polymorphism only?
getMappedSuperclass
public String getMappedSuperclass()
- Get the class that this class is mapped as a subclass of -
not necessarily the direct superclass
getDiscriminatorSQLValue
public String getDiscriminatorSQLValue()
- Get the discriminator value for this particular concrete subclass,
as a string that may be embedded in a select statement
identifierSelectFragment
public String identifierSelectFragment(String name,
String suffix)
- Given a query alias and an identifying suffix, render the intentifier select fragment.
propertySelectFragment
public String propertySelectFragment(String alias,
String suffix,
boolean allProperties)
- Given a query alias and an identifying suffix, render the property select fragment.
getIdentifierColumnNames
public String[] getIdentifierColumnNames()
- Get the names of columns used to persist the identifier
- Specified by:
getIdentifierColumnNames in interface Loadable
isMultiTable
public boolean isMultiTable()
- Is the inheritence hierarchy described by this persister contained across
multiple tables?
- Returns:
- True if the inheritence hierarchy is spread across multiple tables; false otherwise.
getConstraintOrderedTableNameClosure
public String[] getConstraintOrderedTableNameClosure()
- Get the names of all tables used in the hierarchy (up and down) ordered such
that deletes in the given order would not cause contraint violations.
- Returns:
- The ordered array of table names.
getContraintOrderedTableKeyColumnClosure
public String[][] getContraintOrderedTableKeyColumnClosure()
- For each table specified in
getConstraintOrderedTableNameClosure(), get
the columns that define the key between the various hierarchy classes.
The first dimension here corresponds to the table indexes returned in
getConstraintOrderedTableNameClosure().
The second dimension should have the same length across all the elements in
the first dimension. If not, that'd be a problem ;)
- Returns:
getTemporaryIdTableName
public String getTemporaryIdTableName()
- Get the name of the temporary table to be used to (potentially) store id values
when performing bulk update/deletes.
- Returns:
- The appropriate temporary table name.
getTemporaryIdTableDDL
public String getTemporaryIdTableDDL()
- Get the appropriate DDL command for generating the temporary table to
be used to (potentially) store id values when performing bulk update/deletes.
- Returns:
- The appropriate temporary table creation command.
getSubclassPropertyTableNumber
public int getSubclassPropertyTableNumber(String propertyPath)
- Given a property name, determine the number of the table which contains the column
to which this property is mapped.
Note that this is not relative to the results from
getConstraintOrderedTableNameClosure().
It is relative to the subclass table name closure maintained internal to the persister (yick!).
It is also relative to the indexing used to resolve getSubclassTableName(int)...
- Parameters:
propertyPath - The name of the property.
- Returns:
- The nunber of the table to which the property is mapped.
getSubclassPropertyDeclarer
public Queryable.Declarer getSubclassPropertyDeclarer(String propertyPath)
- Determine whether the given property is declared by our
mapped class, our super class, or one of our subclasses...
Note: the method is called 'subclass property...' simply
for consistency sake (e.g.
getSubclassPropertyTableNumber(java.lang.String)
- Parameters:
propertyPath - The property name.
- Returns:
- The property declarer
getSubclassTableName
public String getSubclassTableName(int number)
- Get the name of the table with the given index from the internal
array.
- Parameters:
number - The index into the internal array.
- Returns:
isVersionPropertyInsertable
public boolean isVersionPropertyInsertable()
- Is the version property included in insert statements?
generateFilterConditionAlias
public String generateFilterConditionAlias(String rootAlias)
- The alias used for any filter conditions (mapped where-fragments or
enabled-filters).
This may or may not be different from the root alias depending upon the
inheritence mapping strategy.
- Parameters:
rootAlias - The root alias
- Returns:
- The alias used for "filter conditions" within the where clause.
