Method Detail

applyConstrainingFacet

public RestrictedDatatype<Duration> applyConstrainingFacet(aterm.ATermAppl facet,
                                                  Object value)
                                                    throws InvalidConstrainingFacetException

Description copied from interface: RestrictedDatatype

Apply a constraining facet to further restrict the value space

Specified by:

applyConstrainingFacet in interface RestrictedDatatype<Duration>

Parameters:

facet - the constraining facet name (typically a URI)

value - the value for the constraining facet. This is not necessarily in the value space of the base datatype (e.g., length facet values on string types are not)

Returns:

the further restricted value space

Throws:

InvalidConstrainingFacetException

contains

public boolean contains(Object value)

Description copied from interface: DataRange

Check if a data range contains a particular value

Specified by:

contains in interface DataRange<Duration>

Parameters:

value - the value to check

Returns:

true if the data range contains value, false else

containsAtLeast

public boolean containsAtLeast(int n)

Description copied from interface: DataRange

Check that a data range contains a minimum number of elements

Specified by:

containsAtLeast in interface DataRange<Duration>

Parameters:

n - the number of elements

Returns:

true if the data range contains n or more elements, false otherwise

exclude

public RestrictedDatatype<Duration> exclude(Collection<?> values)

Description copied from interface: RestrictedDatatype

Exclude specific elements from the data range. Used when a restricted data range is in a conjunction with a negative enumeration. Elements in values that are not contained in the restriction are ignored.

Specified by:

exclude in interface RestrictedDatatype<Duration>

Parameters:

values - The values to exclude

Returns:

A new RestrictedDatatype

getDatatype

public Datatype<? extends Duration> getDatatype()

Description copied from interface: RestrictedDatatype

Query for the base datatype of a restricted datatype. This is not necessarily a primitive datatype.

Specified by:

getDatatype in interface RestrictedDatatype<Duration>

Returns:

the base datatype

getValue

public Duration getValue(int i)

Description copied from interface: DataRange

Return a value from an enumerable data range. Necessary to support LiteralValueBranch shiftTryNext

Specified by:

getValue in interface DataRange<Duration>

Parameters:

i - the index of the value in the data range

Returns:

the value

intersect

public RestrictedDatatype<Duration> intersect(RestrictedDatatype<?> other,
                                     boolean negated)

Description copied from interface: RestrictedDatatype

Intersect this range with another range. It must be the case that getDatatype().getPrimitiveDatatype().equals( other.getDatatype.getPrimiveDatatype()

Specified by:

intersect in interface RestrictedDatatype<Duration>

Parameters:

other - restricted datatype to merge into this

negated - true if other is negated, false else

Returns:

a new RestrictedDatatype, representing the intersection of this and other

isEmpty

public boolean isEmpty()

Description copied from interface: DataRange

Convenience method equivalent to !containsAtLeast(0)

Specified by:

isEmpty in interface DataRange<Duration>

Returns:

true if the data range contains no elements, false otherwise

isEnumerable

public boolean isEnumerable()

Description copied from interface: DataRange

Query if values in the data range can be enumerated.

Specified by:

isEnumerable in interface DataRange<Duration>

Returns:

true if the data range is enumerable, false otherwise

isFinite

public boolean isFinite()

Description copied from interface: DataRange

Query if there are a finite number of values in the data range.

Specified by:

isFinite in interface DataRange<Duration>

Returns:

true if the data range is finite, false otherwise

size

public int size()

Description copied from interface: DataRange

Return the size of the data range. Necessary to support LiteralValueBranch constructor

Specified by:

size in interface DataRange<Duration>

Returns:

the size of the data range

union

public RestrictedDatatype<Duration> union(RestrictedDatatype<?> other)

Description copied from interface: RestrictedDatatype

Union this range with another range. It must be the case that getDatatype().getPrimitiveDatatype().equals( other.getDatatype.getPrimiveDatatype()

Specified by:

union in interface RestrictedDatatype<Duration>

Parameters:

other - restricted datatype to merge with this

Returns:

a new RestrictedDatatype, representing the intersection of this and other

valueIterator

public Iterator<Duration> valueIterator()

Description copied from interface: DataRange

Get a (possibly infinite) iterator over values in the data range.

Specified by:

valueIterator in interface DataRange<Duration>

Returns:

an Iterator
