net.sf.saxon.value.ShareableSequence
| ShareableSequence | | final public class ShareableSequence extends Value (Code) | | A sequence value implemented extensionally using an extensible List whose leading part can be shared
with other sequence values. The list can be appended to by other users (at most one other user!),
but the items within the range used by this sequence value cannot be modified.
|
| ShareableSequence | | public ShareableSequence(List list)(Code) | | Construct an sequence from an array of items. Note, the list of items is used as is,
which means the caller must not subsequently change its contents; however it is permitted
to subsequently append items to the list (indeed, that is the raison d'etre of this class)
Parameters:
list - the list of items to be included in the sequence |
| getCardinality | | public int getCardinality()(Code) | | Determine the cardinality
the cardinality of the sequence, using the constants defined innet.sf.saxon.value.Cardinality
See Also: Cardinality |
| getImplementationMethod | | public int getImplementationMethod()(Code) | | An implementation of Expression must provide at least one of the methods evaluateItem(), iterate(), or process().
This method indicates which of these methods is preferred.
|
| getItemType | | public ItemType getItemType(TypeHierarchy th)(Code) | | Get the (lowest common) item type
integer identifying an item type to which all the items in thissequence conform
Parameters:
th - |
| getLength | | public int getLength()(Code) | | Get the number of items in the sequence
the number of items in the sequence |
| getList | | public List getList()(Code) | | Get the underlying list
|
| isShareable | | public boolean isShareable()(Code) | | Determine whether another value can share this list. This is true provided the list has
not already been extended by another value.
|
| itemAt | | public Item itemAt(int n)(Code) | | Get the n'th item in the sequence (starting with 0 as the first item)
Parameters:
n - the position of the required item the n'th item in the sequence |
| iterate | | public SequenceIterator iterate(XPathContext context)(Code) | | Return an iterator over this sequence.
Parameters:
context - dynamic evaluation context; not used in thisimplementation of the method the required SequenceIterator, positioned at the start of thesequence |
| reduce | | public Value reduce()(Code) | | Reduce a value to its simplest form. If the value is a closure or some other form of deferred value
such as a FunctionCallPackage, then it is reduced to a SequenceExtent. If it is a SequenceExtent containing
a single item, then it is reduced to that item. One consequence that is exploited by class FilterExpression
is that if the value is a singleton numeric value, then the result will be an instance of NumericValue
|
| simplify | | public Value simplify()(Code) | | Simplify this value
