Enum Constants

Enum Constant	Description
ASCENDING	Indicates that an ascending sort, in the collation sequence of the underlying data store, is performed.
DESCENDING	Indicates that a descending sort, in the collation sequence of the filter expression processor, is performed.

Enum Constant Details

ASCENDING

@UML(identifier="ascending",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SortOrder ASCENDING

Indicates that an ascending sort, in the collation sequence of the underlying data store, is performed. This is the SortProperty default value.

DESCENDING

@UML(identifier="descending",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SortOrder DESCENDING

Indicates that a descending sort, in the collation sequence of the filter expression processor, is performed.

Method Details

values

public static SortOrder[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static SortOrder valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

identifier

public String identifier()

Returns the UML identifier for this enumeration constant.

Specified by:

identifier in interface ControlledVocabulary

Returns:

the ISO/OGC identifier for this constant, or null if none.

toSQL

public String toSQL()

Returns the name used in SQL statements. This is "ASC" or "DESC".

Returns:

name used in SQL statements.

names

public String[] names()

Returns the programmatic name of this constant together with its identifier and SQL name.

Specified by:

names in interface ControlledVocabulary

Returns:

all names of this constant. This array is never null and never empty.

family

public SortOrder[] family()

Returns all constants defined by this enumeration type. Invoking this method is equivalent to invoking values(), except that this method can be invoked on an instance of the ControlledVocabulary interface (i.e. the enumeration type does not need to be known at compile-time).

Specified by:

family in interface ControlledVocabulary

Returns:

all values for this enumeration.
