Direct Known Subclasses:

URIRestriction

public abstract class LengthRestriction
extends TypeRestriction

Implementation of XSD Value Restrictions: it contains all values (literals or individuals) that meet the specified conditions. These conditions are either:

1. length
2. min length
3. max length

It is possible to define a condition on the min value and on the max value in the same LengthRestriction.

copyTo

public TypeExpression copyTo(LengthRestriction copy)

Helper method to copy Restrictions.

TypeExpression.copy()

isWellFormed

public boolean isWellFormed()

Description copied from class: TypeExpression

Returns true, if the state of the resource is valid, otherwise false. Redefined in this class as abstract to force subclasses to override it.

Specified by:

isWellFormed in class TypeExpression

See Also:

Resource.isWellFormed()

hasMember

public boolean hasMember(Object member,
                HashMap context,
                int ttl,
                List<MatchLogEntry> log)

Description copied from class: TypeExpression

Returns true if the given object is a member of the class represented by this type expression, otherwise false. The context table maps the URIs of certain variables onto values currently assigned to them. The variables are either standard variables managed by the universAAL middleware or parameters of a specific service in whose context this method is called. Both the object whose membership is going to be checked and this type expression may contain references to such variables. If there is already a value assigned to such a referenced variable, it must be replaced by the associated value, otherwise this method may expand the context table by deriving a value for such unassigned but referenced variables with which the membership can be asserted. In case of returning true, the caller must check the size of the context table to see if new conditions are added in order for the membership to be asserted. If the context table is null, the method does a global and unconditional check.

Overrides:

hasMember in class TypeRestriction

Parameters:

member - the object whose membership is going to be checked

context - context of the matchmaking. May be null.

ttl - time-to-live parameter

log - list that can be filled with log entries. May be null.

Returns:

true if the specified member is a member of this type expression

matches

public boolean matches(TypeExpression subset,
              HashMap context,
              int ttl,
              List<MatchLogEntry> log)

Not supported. Always returns false.

Specified by:

matches in class TypeExpression

Parameters:

subset - the type expression with which the compatibility is going to be checked

context - context of the matchmaking. May be null.

ttl - time-to-live parameter

log - list that can be filled with log entries. May be null.

Returns:

true if the given type expression is a subset of the class represented by this type expression, otherwise false

See Also:

Constants.VAR_uAAL_ACCESSING_BUS_MEMBER, Constants.VAR_uAAL_ACCESSING_HUMAN_USER, Constants.VAR_uAAL_CURRENT_DATETIME, Constants.VAR_uAAL_SERVICE_TO_SELECT

isDisjointWith

public boolean isDisjointWith(TypeExpression other,
                     HashMap context,
                     int ttl,
                     List<MatchLogEntry> log)

Not supported. Always returns false.

Specified by:

isDisjointWith in class TypeExpression

Parameters:

other - the type expression with which the disjointness is going to be checked

context - context of the matchmaking. May be null.

ttl - time-to-live parameter

log - list that can be filled with log entries. May be null.

Returns:

true if the given type expression has no member in common with the class represented by this type expression, otherwise false

Constants.VAR_uAAL_ACCESSING_BUS_MEMBER, Constants.VAR_uAAL_ACCESSING_HUMAN_USER, Constants.VAR_uAAL_CURRENT_DATETIME, Constants.VAR_uAAL_SERVICE_TO_SELECT

setProperty

public boolean setProperty(String propURI,
                  Object o)

Description copied from class: Resource

Adds a statement with this resource as the subject, the given propURI as the predicate and the given value as the object. Subclasses must override this in order to decide if the statement to be added fits the general class constraints. If not, the call of this method should be ignored. For each property only one single call may be made to this method, unless subsequent calls to this method for setting the value of the same property are treated as an update for an update-able property. Multi-valued properties must be set using an instance of List. The differentiation, if a such list should be treated as an rdf:List, can be made with the help of Resource.isClosedCollection(String). The default implementation here accepts all property-value pairs blindly except for rdf:type which is handled if the value is a type URI, a Resource or a java.util.List of them.

Note: The setting of the property rdf:type is being handled by this class via the final methods Resource.addType(String, boolean), Resource.getType(), and Resource.getTypes(). Although these methods give the view of handling type URIs as strings, but in reality the types are stored as direct instances of this class. So, the subclasses should ignore calls for setting rdf:type; if not, then the subclass must pay attention that the value should be a List of direct instances of this class so that (1) the Resource.toString() method returns just the URI and (2) the serializers get no problems with the value. Also, settings via subclasses may be overwritten by this class if a subsequent call to Resource.addType(String, boolean) is made.

Overrides:

setProperty in class TypeRestriction

Returns:

true if the property changed as a result of the call

Resource.setProperty(String, Object)
