java.lang.Objectnet.crisopeya.product.SEO_Domain_Index_rg.SEO_Domain_Index_rgStaticScheme
public class SEO_Domain_Index_rgStaticScheme
Holds all the SEO Domain Index (external link)
application defined requirements. It is used by the CRISOPEYA Platform
logic, together with the SEO_Domain_Index_rgStaticModel to retrieve SEO Domain Index (external link) IM
scheme information.
It also contains all the required information to generate an updated
version of the application.
Scheme Information
This class is a member of the Crisopeya IM Scheme Framework. The
IM scheme information is divided into six classes according to the
application layer scope and the interface implementation, as shown in
the following diagram:
SEO_Domain_Index_rgStaticModel, SEO_Domain_Index_rgModel, SEO_Domain_Index_rgDbStaticModel, SEO_Domain_Index_rgDbModel, SEO_Domain_Index_rgUiStaticModel and SEO_Domain_Index_rgUiModelScheme interface, the SEO_Domain_Index_rgScheme utility class is implemented.
java.util.List lists
are used to store scheme information, instead of arrays, because Java
arrays objects cannot be immutable. An immutable object is one whose
externally visible state cannot change after it is instantiated.
Immutable objects are inherently thread-safe and cannot get into an
inconsistent state. You can freely share and cache these object
references without having to copy or clone them. Most of the CRISOPEYA
IM Scheme information is immutable, and therefore the Class that bests
suits for scheme information management should be referenced as
immutable.final keyword is included in Java to declare
immutability. However, while fields can be declared final;
array, list and collection elements cannot. To avoid this limitation,
the Collections.unmodifiableCollection wrapper implementation returns an
unmodifiable view of the specified Lists, making
that reference inmutable.
static final String[] DATATYPES = {...};
Then the SEO Domain Index (external link)
DATATYPES Scheme information would not be immutable for a caller who
gets the field reference. With the field reference, he could modify the
DATATYPES array content using, for example, the following assignment:
DATATYPES[0] = DataTypes.TEXT;
Instead, to overcome this limitation, a DATATYPE List is used for the scheme DATATYPES declaration:
static final List<String> DATATYPES = Arrays.asList(...);
And all DATATYPES field references get an unmodifiable DATATYPES List though SEO_Domain_Index_rgScheme using the Collections.unmodifiableCollection wrapper:
public List<String> getDatatypes() {
return Collections.unmodifiableList(DATATYPES);
}
If a caller who obtains a reference tries to change the list contents
using, for example, the following code:
DATATYPES.set(0, DataTypes.TEXT);
Then no modification would be made and an UnsupportedOperationException
will be thrown.
