Field Detail

CACHE_POLICY

public static final Key<MetaParams,CachePolicy> CACHE_POLICY

Session cache policy. The default value is PROTECTED_CACHE.

See Also:

Parameter values

TABLE_ALIAS_PREFIX

public static final Key<MetaParams,String> TABLE_ALIAS_PREFIX

Special prameter for an automatically assembled table alias prefix. The default value is the empty string.

TABLE_ALIAS_SUFFIX

public static final Key<MetaParams,String> TABLE_ALIAS_SUFFIX

Special prameter for an automatically assembled table alias prefix. The default value is the empty String.

SEQUENCE_CACHE

public static final Key<MetaParams,Integer> SEQUENCE_CACHE

Sequential cache parameter saves the number of requests to the following sequence when a insert statement into DB. The value of the parameter is used only when creating a new DB, indivuální ORM changes for each table can be changed any time later in the column 'cache' of table 'ormujo_pk_support' . Default values is 100, the smallest possible value is 1.

ORM2DLL_POLICY

public static final Key<MetaParams,Orm2ddlPolicy> ORM2DLL_POLICY

A policy to defining the database structure by a DDL. The default value is option: CREATE_OR_UPDATE_DDL.

See Also:

Parameter values

COMMENT_POLICY

public static final Key<MetaParams,CommentPolicy> COMMENT_POLICY

A policy for assigning an annotation table comment Comment to database. The default value is ON_ANY_CHANGE.

See Also:

Parameter values

SAVE_CONFIG_TO_FILE

public static final Key<MetaParams,File> SAVE_CONFIG_TO_FILE

Framework can save the final configuration file to a new file for an external use. If this parameter is null than the save action is skipped.

TYPE_SERVICE

public static final Key<MetaParams,Class<? extends ITypeService>> TYPE_SERVICE

The instance of the parameter class ITypeService is used for conversion, reading and writting to/from the ResultSet. You can specify a sybtype of the class for a commiono special fetures.

See Also:

Column.converter()

CHECK_KEYWORDS

public static final Key<MetaParams,CheckReport> CHECK_KEYWORDS

CheckReport a keyword in the database table or colum name inside the meta-model. The default value is EXCEPTION.

See Also:

Parameter values

MAX_ITEM_COUNT_4_IN

public static final Key<MetaParams,Integer> MAX_ITEM_COUNT_4_IN

The maximal count of items for the SQL IN operator, default value is 500 items The limit is used inside the method loadLazyValuesAsBatch(..).

See Also:

OrmTools.loadLazyValuesAsBatch(java.lang.Iterable, org.ujorm.Key)

SEQUENCE_SCHEMA_SYMBOL

public static final Key<MetaParams,Boolean> SEQUENCE_SCHEMA_SYMBOL

The parameter value TRUE affects to a Sequence key name in the internal sequence generator. Value TRUE generate a special character "~" instead of default database schema in the sequence table. The benefit of the special chatacter can be evaluated in the case of the renaming of the database schema. In case of change of the parameter value is necessary to convert values in the database column 'ujorm_pk_support.id' by hand. The default value is FALSE.

INHERITANCE_MODE

public static final Key<MetaParams,Boolean> INHERITANCE_MODE

Any action type or CREATE, UPDATE, DELETE on inheritance objects calls the same action to its 'parrent' object. If the mode is off than you must take care of all its parents in the code handy. The default falue is TRUE.
Note: the parameter does not affect the opearations batch update or batch delete due direct modification of database.

MetaTable.getParent(..)

INSERT_MULTIROW_ITEM_LIMIT

public static final Key<MetaParams,Integer> INSERT_MULTIROW_ITEM_LIMIT

The parameter is used to limit of the insert sttatemtn in case the "sql multirow insert". The default value is 100.

See Also:

save(List)

MORE_PARAMS

public static final Key<MetaParams,MoreParams> MORE_PARAMS

The parameter contains the special parameters with for different use.

See Also:

MoreParams

LOG_METAMODEL_INFO

public static final Key<MetaParams,Boolean> LOG_METAMODEL_INFO

Set a logging level for a full meta-model information in the XML format. The TRUE value means the INFO level and the FALSE value means the FINE logging level.

LOGBACK_LOGGING_SUPPORT

public static final Key<MetaParams,Boolean> LOGBACK_LOGGING_SUPPORT

Pamameter tries to install a brighe to the Logback logging framework using a statement SLF4JBridgeHandler.install();

APPL_CONTEXT

public static final Key<MetaParams,Object> APPL_CONTEXT

An application context for initializaton of the customer componets of the meta-model.
