#include <DbXml.hpp> bool XmlIndexSpecification::find( const std::string &uri, const std::string &name, std::string &index)
Returns the indexing strategies for a named document or metadata node. This method returns true if an index for the node is found; otherwise, it returns false.
See XmlIndexSpecification::addIndex for more information on index strategies.
The namespace of the node to be indexed. The default namespace is selected by passing an empty string for the namespace.
A comma-separated list of strings that represent the indexing strategy. The strings must contain the following information in the following order:
unique
-{path type}-{node type}-{key type}-{syntax}
where:
unique indicates that the indexed value is unique in the container. If this keyword does not appear on the index string, then the indexed value is not required to be unique in the container.
{path type} is either node
or edge
.
{node type} is one of element
,
attribute
, or
metadata
. If
metadata
is specified, then
{path type} must be node
.
{key type} is one of presence
, equality
, or
substring
.
{syntax} identifies the type of information being indexed. It must be one of the following values:
none | double | gYear |
base64Binary | duration | gYearMonth |
boolean | float | hexBinary |
date | gDay | string |
dateTime | gMonth | time |
decimal | gMonthDay |
Note that if {key type} is presence
, then {syntax} must be
none
or simply not specified.
Some example index strings are:
