java.lang .Object

jodd.db.orm .DbOrm

DbOrm
public class DbOrm (Code)
	Global DB-ORM mapping definitions, prefixes and cache. Mapping definitions are used only by a result set mapper (such as jodd.db.orm.mapper.ResultSetMapper to lookup for an entity from table name. Table names are read from result-set meta data, for example. Moreover, it is not needed to use mappings at all: in that case just provide entity types during result set to objects conversion.

Field Summary
protected String	columnAliasSeparator
protected Map<Class, DbEntityDescriptor>	descriptors
protected static DbOrm	orm
protected String	packagePrefix
protected String	tablePrefix

Constructor Summary
protected	DbOrm() Singleton.

Method Summary
public void	clearDescriptorsCache() Clears descriptors cache.
public String	getColumnAliasSeparator() Returns value for separator for column aliases that divides table reference and column name.
public static DbOrm	getInstance() Returns current DB-ORM instance.
public String	getPackagePrefix() Returns current package prefix.
public String	getTablePrefix() Returns current table prefix.
public DbEntityDescriptor	lookup(Class type) Lookups for DbEntityDescriptor .
public void	setColumnAliasSeparator(String separator) Specifies separator for column aliases that divides table reference and column name.
public static void	setInstance(DbOrm orm) Sets new default instance for DB-ORM mapper.
public DbOrm	setPackagePrefix(String prefix) Sets package prefix for all DB entities.
public DbOrm	setTablePrefix(String prefix) Sets default table prefix for all tables.

Field Detail

columnAliasSeparator
protected String columnAliasSeparator(Code)

descriptors
protected Map<Class, DbEntityDescriptor> descriptors(Code)

orm
protected static DbOrm orm(Code)

packagePrefix
protected String packagePrefix(Code)

tablePrefix
protected String tablePrefix(Code)

Constructor Detail

DbOrm
protected DbOrm()(Code)
	Singleton.

Method Detail

clearDescriptorsCache
public void clearDescriptorsCache()(Code)
	Clears descriptors cache.

getColumnAliasSeparator
public String getColumnAliasSeparator()(Code)
	Returns value for separator for column aliases that divides table reference and column name.

getInstance
public static DbOrm getInstance()(Code)
	Returns current DB-ORM instance.

getPackagePrefix
public String getPackagePrefix()(Code)
	Returns current package prefix.

getTablePrefix
public String getTablePrefix()(Code)
	Returns current table prefix.

lookup
public DbEntityDescriptor lookup(Class type)(Code)
	Lookups for DbEntityDescriptor . If it doesn't exist, new one will be created. Returns `null` for core classes from `java` runtime packages.

setColumnAliasSeparator
public void setColumnAliasSeparator(String separator)(Code)
	Specifies separator for column aliases that divides table reference and column name. Separator should contains of characters that are not used in table names, such as: '$' or '__'.

setInstance
public static void setInstance(DbOrm orm)(Code)
	Sets new default instance for DB-ORM mapper. If parameter is `null` current instance will be replaced with new instance of this class.

setPackagePrefix
public DbOrm setPackagePrefix(String prefix)(Code)
	Sets package prefix for all DB entities. Used by jodd.db.orm.sqlgen.DbSqlGenerator during creating sql queries.

setTablePrefix
public DbOrm setTablePrefix(String prefix)(Code)
	Sets default table prefix for all tables. This prefix affect default conversions from bean name to table name and vice-versa when no annotations are used.
