Field Detail

CACHE_POLICY

public static final org.ujorm.extensions.Property<MetaParams,CachePolicy> CACHE_POLICY

Session cache policy. The default value is PROTECTED_CACHE.

Parameter values

TABLE_ALIAS_PREFIX

public static final org.ujorm.extensions.Property<MetaParams,java.lang.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 org.ujorm.extensions.Property<MetaParams,java.lang.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 org.ujorm.extensions.Property<MetaParams,java.lang.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 org.ujorm.extensions.Property<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 org.ujorm.extensions.Property<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 org.ujorm.extensions.Property<MetaParams,java.io.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 org.ujorm.extensions.Property<MetaParams,java.lang.Class> TYPE_SERVICE

Change a TypeService class by a subtype for user type customization.

See Also:

TypeService

CHECK_KEYWORDS

public static final org.ujorm.extensions.Property<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 org.ujorm.extensions.Property<MetaParams,java.lang.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.UjoProperty)

SEQUENCE_SCHEMA_SYMBOL

public static final org.ujorm.extensions.Property<MetaParams,java.lang.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 org.ujorm.extensions.Property<MetaParams,java.lang.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.

save(List)

MORE_PARAMS

public static final org.ujorm.extensions.Property<MetaParams,MoreParams> MORE_PARAMS

The parameter contains the special parameters with for different use.

APPL_CONTEXT

public static final org.ujorm.extensions.Property<MetaParams,java.lang.Object> APPL_CONTEXT

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