public final class SequenceType
extends java.lang.Object
implements Serializable
SequenceType: a sequence type consists of a primary type, which indicates the type of item,
and a cardinality, which indicates the number of occurrences permitted. Where the primary type
is element or attribute, there may also be a content type, indicating the required type
annotation on the element or attribute content.
ANY_SEQUENCE
public static final SequenceType ANY_SEQUENCE
A type that allows any sequence of items
ATOMIC_SEQUENCE
public static final SequenceType ATOMIC_SEQUENCE
A type that allows zero or more atomic values
EMPTY_SEQUENCE
public static final SequenceType EMPTY_SEQUENCE
A type that only permits the empty sequence
NODE_SEQUENCE
public static final SequenceType NODE_SEQUENCE
A type that allows a sequence of zero or more nodes
NUMERIC_SEQUENCE
public static final SequenceType NUMERIC_SEQUENCE
A type that allows a sequence of zero or more numeric values
OPTIONAL_ATOMIC
public static final SequenceType OPTIONAL_ATOMIC
A type that allows zero or one atomic values
OPTIONAL_INTEGER
public static final SequenceType OPTIONAL_INTEGER
A type that allows a single optional integer
OPTIONAL_NODE
public static final SequenceType OPTIONAL_NODE
A type that allows zero or one nodes
OPTIONAL_NUMERIC
public static final SequenceType OPTIONAL_NUMERIC
A type that allows an optional numeric value
SINGLE_ATOMIC
public static final SequenceType SINGLE_ATOMIC
A type that allows exactly one atomic value
SINGLE_DOUBLE
public static final SequenceType SINGLE_DOUBLE
A type that allows a single double
SINGLE_INTEGER
public static final SequenceType SINGLE_INTEGER
A type that allows a single integer
SINGLE_ITEM
public static final SequenceType SINGLE_ITEM
A type that allows exactly one item, of any kind
SINGLE_NODE
public static final SequenceType SINGLE_NODE
A type that allows a single node
SINGLE_STRING
public static final SequenceType SINGLE_STRING
A type that allows a single string
equals
public boolean equals(Object obj)
Indicates whether some other object is "equal to" this one.
getCardinality
public int getCardinality()
Get the cardinality component of this SequenceType. This is one of the constants Cardinality.EXACTLY_ONE,
Cardinality.ONE_OR_MORE, etc
getPrimaryType
public ItemType getPrimaryType()
Get the "primary" part of this required type. E.g. for type element(*, xs:date) the "primary type" is element()
- The item type code of the primary type
hashCode
public int hashCode()
Returns a hash code value for the object.
makeSequenceType
public static SequenceType makeSequenceType(ItemType primaryType,
int cardinality)
Construct an instance of SequenceType. This is a factory method: it maintains a
pool of SequenceType objects to reduce the amount of object creation.
primaryType
- The item typecardinality
- The required cardinality
toString
public String toString()
Return a string representation of this SequenceType
- the string representation as an instance of the XPath
SequenceType construct
