Axis

public final class Axis extends Object
Specifies values related to XPath Axes.

The ancestor, descendant, following, preceding and self axes partition a document (ignoring attribute and namespace nodes): they do not overlap and together they contain all the nodes in the document.

Fields Summary
public static final int
ANCESTOR
The ancestor axis contains the ancestors of the context node; the ancestors of the context node consist of the parent of context node and the parent's parent and so on; thus, the ancestor axis will always include the root node, unless the context node is the root node.
public static final int
ANCESTORORSELF
the ancestor-or-self axis contains the context node and the ancestors of the context node; thus, the ancestor axis will always include the root node.
public static final int
ATTRIBUTE
the attribute axis contains the attributes of the context node; the axis will be empty unless the context node is an element.
public static final int
CHILD
The child axis contains the children of the context node.
public static final int
DESCENDANT
The descendant axis contains the descendants of the context node; a descendant is a child or a child of a child and so on; thus the descendant axis never contains attribute or namespace nodes.
public static final int
DESCENDANTORSELF
The descendant-or-self axis contains the context node and the descendants of the context node.
public static final int
FOLLOWING
the following axis contains all nodes in the same document as the context node that are after the context node in document order, excluding any descendants and excluding attribute nodes and namespace nodes.
public static final int
FOLLOWINGSIBLING
The following-sibling axis contains all the following siblings of the context node; if the context node is an attribute node or namespace node, the following-sibling axis is empty.
public static final int
NAMESPACEDECLS
The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.
public static final int
NAMESPACE
The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.
public static final int
PARENT
The parent axis contains the parent of the context node, if there is one.
public static final int
PRECEDING
The preceding axis contains all nodes in the same document as the context node that are before the context node in document order, excluding any ancestors and excluding attribute nodes and namespace nodes
public static final int
PRECEDINGSIBLING
The preceding-sibling axis contains all the preceding siblings of the context node; if the context node is an attribute node or namespace node, the preceding-sibling axis is empty.
public static final int
SELF
The self axis contains just the context node itself.
public static final int
ALLFROMNODE
A non-xpath axis, traversing the subtree including the subtree root, descendants, attributes, and namespace node decls.
public static final int
PRECEDINGANDANCESTOR
A non-xpath axis, traversing the the preceding and the ancestor nodes, needed for inverseing select patterns to match patterns.
public static final int
ALL
A non-xpath axis, returns all nodes in the tree from and including the root.
public static final int
DESCENDANTSFROMROOT
A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.
public static final int
DESCENDANTSORSELFFROMROOT
A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.
public static final int
ROOT
A non-xpath axis, returns root only.
public static final int
FILTEREDLIST
A non-xpath axis, for functions.
private static final boolean[]
isReverse
A table to identify whether an axis is a reverse axis;
private static final String[]
names
The names of the axes for diagnostic purposes.
