Constructor Summary

InsertionOrderNodeSet()
Construct a new, empty node-set

InsertionOrderNodeSet(Collection copy)
Construct a new node-set and initialize it to contain the members in the passed collection

InsertionOrderNodeSet(NodeSet copy)
Construct a new node-set with the same content as the passed node-set

Method Summary

void	castFrom(Object type) Convert from a different type of expression value to the NodeSet type NOTE: this will ALWAYS throw an exception (unless the "from" type is a node-set), since there is no type type can be converted to a node-set
int	order() Return order in which nodes are returned from first()-next()
void	union(NodeSet rhs) Perform a union operation between this node-set and another node-set.

Constructor Detail

InsertionOrderNodeSet

public InsertionOrderNodeSet()

Construct a new, empty node-set

InsertionOrderNodeSet

public InsertionOrderNodeSet(Collection copy)
                      throws Exception

Construct a new node-set and initialize it to contain the members in the passed collection

Parameters:

copy - A collection of Node objects

Throws:

Exception - Error

InsertionOrderNodeSet

public InsertionOrderNodeSet(NodeSet copy)

Construct a new node-set with the same content as the passed node-set

Parameters:

copy - The node-set to copy

Method Detail

union

public void union(NodeSet rhs)

Perform a union operation between this node-set and another node-set. The resulting union will be in document order.

Overrides:

union in class NodeSet

Parameters:

rhs - The right-hand operand of the union operator

castFrom

public void castFrom(Object type)
              throws XPathConversionException

Convert from a different type of expression value to the NodeSet type

NOTE: this will ALWAYS throw an exception (unless the "from" type is a node-set), since there is no type type can be converted to a node-set

Specified by:

castFrom in interface ExpressionValue

Overrides:

castFrom in class NodeSet

Parameters:

type - The object to convert from.

Throws:

XPathConversionException

order

public int order()

Return order in which nodes are returned from first()-next()

Specified by:

order in interface ContextNodeList

Overrides:

order in class NodeSet

Returns:

DOCUMENT_ORDER or REVERSE_DOCUMENT_ORDER
