AbstractPattern |
copyAxis()
Returns the node itself for the axis. |
AbstractPattern |
copyPosition()
Returns null since the axis isn't part of the position pattern. |
int |
count(org.w3c.dom.Node node,
Env env,
AbstractPattern pattern)
Counts all siblings matching the pattern. |
NodeIterator |
createNodeIterator(org.w3c.dom.Node node,
ExprEnvironment env,
AbstractPattern match)
Creates a new node iterator. |
boolean |
equals(java.lang.Object b)
Returns true if the two patterns are equal. |
org.w3c.dom.Node |
firstNode(org.w3c.dom.Node node,
ExprEnvironment env)
Returns the first node in the selection order. |
boolean |
isStrictlyAscending()
Returns true if the pattern is strictly ascending. |
boolean |
isUnique()
Returns true if the pattern's selector returns unique nodes. |
boolean |
match(org.w3c.dom.Node node,
ExprEnvironment env)
Matches all nodes except attributes and tests the parent pattern with the parent node. |
org.w3c.dom.Node |
nextNode(org.w3c.dom.Node node,
org.w3c.dom.Node lastNode)
Returns the next node in the selection order. |
int |
position(org.w3c.dom.Node node,
Env env,
AbstractPattern pattern)
The position of the child is the count of previous siblings matching the pattern. |
