- All Implemented Interfaces:
java.io.Serializable
public final class SequenceType extends java.lang.Object implements java.io.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.- See Also:

Method Detail
-
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.- Parameters:
primaryType
- The item typecardinality
- The required cardinality
-
getPrimaryType
public ItemType getPrimaryType()
Get the "primary" part of this required type. E.g. for type element(*, xs:date) the "primary type" is element()- Returns:
- The item type code of the primary type
-
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- Returns:
- the required cardinality
- See Also:
Cardinality
-
toString
public java.lang.String toString()
Return a string representation of this SequenceType- Overrides:
toString
in classjava.lang.Object
- Returns:
- the string representation as an instance of the XPath SequenceType construct
-
hashCode
public int hashCode()
Returns a hash code value for the object.- Overrides:
hashCode
in classjava.lang.Object
-
equals
public boolean equals(java.lang.Object obj)
Indicates whether some other object is "equal to" this one.- Overrides:
equals
in classjava.lang.Object
