java.lang.Object net.sf.saxon.expr.StaticProperty
public abstract class StaticProperty
This class contains constants identifying dependencies that an XPath expression might have on its context.
Field Summary | |
---|---|
static int |
ALL_NODES_UNTYPED
Expression property: this bit indicates that in the result of an expression, any element and attribute nodes that are present will have type annotation xs:untyped or xs:untypedAtomic respectively, and that any document nodes that are present will have no element children whose type annotation is anything other than xs:untyped |
static int |
ALLOWS_MANY
Bit set if multiple values are allowed |
static int |
ALLOWS_ONE
Bit set if a single value is allowed |
static int |
ALLOWS_ONE_OR_MORE
Occurence indicator for "one or more" (+) |
static int |
ALLOWS_ZERO
|
static int |
ALLOWS_ZERO_OR_MORE
Occurence indicator for "zero or more" (*) |
static int |
ALLOWS_ZERO_OR_ONE
Occurence indicator for "zero or one" (?) |
static int |
ATTRIBUTE_NS_NODESET
Expression property: this bit is set by getProperties() in the case of an expression that delivers a set of nodes with the guarantee that every node in the result will be an attribute or namespace of the context node |
static int |
CARDINALITY_MASK
Mask for all cardinality bits |
static int |
CONTEXT_DOCUMENT_NODESET
Expression property: this bit is set by getProperties() in the case of an expression whose item type is node, when the nodes in the result are guaranteed all to be in the same document as the context node. |
static int |
DEPENDENCY_MASK
Mask to select all the dependency bits |
static int |
DEPENDS_ON_ASSIGNABLE_GLOBALS
Bit setting: Expression depends on assignable global variables |
static int |
DEPENDS_ON_CONTEXT_DOCUMENT
Bit setting: Expression depends on the document containing the context node |
static int |
DEPENDS_ON_CONTEXT_ITEM
Bit setting: Expression depends on context item |
static int |
DEPENDS_ON_CURRENT_GROUP
Bit setting: Expression depends on current-group() and/or current-grouping-key() |
static int |
DEPENDS_ON_CURRENT_ITEM
Bit setting: Expression depends on current() item |
static int |
DEPENDS_ON_FOCUS
Combination of bits representing dependencies on the focus |
static int |
DEPENDS_ON_LAST
Bit setting: Expression depends on last() |
static int |
DEPENDS_ON_LOCAL_VARIABLES
Bit setting: Expression depends on local variables |
static int |
DEPENDS_ON_NON_DOCUMENT_FOCUS
Combination of bits representing dependencies on the focus, but excluding dependencies on the current document |
static int |
DEPENDS_ON_POSITION
Bit setting: Expression depends on position() |
static int |
DEPENDS_ON_REGEX_GROUP
Bit setting: Expression depends on regex-group() |
static int |
DEPENDS_ON_RUNTIME_ENVIRONMENT
Bit setting: Expression can't be evaluated at compile time for reasons other than the above |
static int |
DEPENDS_ON_USER_FUNCTIONS
Bit setting: Expression depends on user-defined functions |
static int |
DEPENDS_ON_XSLT_CONTEXT
Combination of bits representing dependencies on the XSLT context |
static int |
EMPTY
Occurence indicator when an empty sequence is required |
static int |
EXACTLY_ONE
Occurence indicator for "exactly one" (default occurrence indicator) |
static int |
HAS_SIDE_EFFECTS
Expression property: this bit indicates that an expression has (or might have) side-effects. |
static int |
MUST_MAINTAIN_POSITION
Expression property: this bit indicates that the expression is required during evaluation to maintain the values of position() and last() because they might be required. |
static int |
NON_CREATIVE
Expression property: this bit is set in the case of an expression that will never return newly created nodes, nor a value that depends on the identity of newly created nodes (for example generate-id(new-node())). |
static int |
NOT_UNTYPED_ATOMIC
Expression property: this bit indicates that although the static type of the expression permits untyped atomic values, it is known that the value will not be untyped atomic. |
static int |
ORDERED_NODESET
Expression property: this bit is set by getProperties() in the case of an expression whose item type is node, when the nodes in the result are in document order. |
static int |
PEER_NODESET
Expression property: this bit is set by getProperties() in the case of an expression that delivers a set of nodes with the guarantee that no node in the set will be an ancestor of any other. |
static int |
REVERSE_DOCUMENT_ORDER
Expression property: this bit is set by getProperties() in the case of an expression that delivers items in the reverse of the correct order, when unordered retrieval is requested. |
static int |
SINGLE_DOCUMENT_NODESET
Expression property: this bit is set in the case of an expression that delivers a set of nodes that are all in the same document (not necessarily the same document as the context node). |
static int |
SPECIAL_PROPERTY_MASK
Mask for "special properties": that is, all properties other than cardinality and dependencies |
static int |
SUBTREE_NODESET
Expression property: this bit is set by getProperties() in the case of an expression that delivers a set of nodes with the guarantee that every node in the result will be a descendant or self, or attribute or namespace, of the context node |
Method Summary | |
