CACHE_POLICY

public static final Property<MetaParams,CachePolicy> CACHE_POLICY

Enable / disable a session cache for the business objects.

CACHE_WEAK_MAP

public static final Property<MetaParams,java.lang.Boolean> CACHE_WEAK_MAP

The parameters enables the the cache implementation by WeakHashMap. The false value use a HashMap implementation. Default value is TRUE.

TABLE_ALIAS_PREFIX

public static final Property<MetaParams,java.lang.String> TABLE_ALIAS_PREFIX

Special prameter for an automatically assembled table alias prefix.

TABLE_ALIAS_SUFFIX

public static final Property<MetaParams,java.lang.String> TABLE_ALIAS_SUFFIX

Special prameter for an automatically assembled table alias prefix.

SEQUENCE_CACHE

public static final 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 64, the smallest possible value is 1.

Method Detail

writeValue

public void writeValue(UjoProperty property,
                       java.lang.Object value)

Description copied from class: QuickUjo

It is a common method for writing all object values, however there is strongly recomended to use a method Property.setValue(Ujo,Object) to an external access for a better type safe. The method have got a strategy place for an implementation of several listeners and validators.
NOTE: If property is an incorrect then method can throws an ArrayIndexOutOfBoundsException.

Specified by:

writeValue in interface Ujo

Overrides:

writeValue in class AbstractMetaModel

Parameters:

property - Property must be a direct type only!

Property.setValue(Ujo,Object)

isCacheEnabled

public boolean isCacheEnabled()

Is the cache enabled?
