void XmlIndexSpecification::deleteIndex(const std::string &uri,
    const std::string &name, Type type, XmlValue::type syntax)

Deletes indexing strategies for a named document or metadata node. To delete an index set for metadata, specify the URI and name used when the metadata was added to the document.

Deletes one or more index strategies from the identified node.

• The namespace of the node for which you want the index deleted. The default namespace is selected by passing an empty string for the namespace.

• The name of the element or attribute node to be indexed.

• 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
  • base64Binary
  • boolean
  • date
  • dateTime
  • decimal
  • double
  • duration
  • float
  • gDay
  • gMonth
  • gMonthDay
  • gYear
  • gYearMonth
  • hexBinary
  • string
  • time

  Note that if {key type} is presence, then {syntax} must be none or simply not specified.

  For example, examples index strings are:

  unique-node-element-presence

  node-element-equality-string

  edge-element-presence-none

  node-element-equality-float

The XmlIndexSpecification::deleteIndex method may fail and throw XmlException, encapsulating one of the following non-zero errors:

• Unknown index specification

Deletes a single index strategy from the identified node.

• The namespace of the node for which you want the index deleted. The default namespace is selected by passing an empty string for the namespace.

• The name of the element or attribute node to be indexed.

• A series of XmlIndexSpecification::Type values bitwise OR'd together to form the index strategy.

  To indicate whether the indexed value must be unique container-wide, use one of the following, or leave the value out entirely:

  • XmlIndexSpecification::UNIQUE_OFF
  • XmlIndexSpecification::UNIQUE_ON

  To identify the path type, use one of the following:

  • XmlIndexSpecification::PATH_NODE
  • XmlIndexSpecification::PATH_EDGE

  To identify the node type, use one of the following:

  • XmlIndexSpecification::NODE_ELEMENT
  • XmlIndexSpecification::NODE_ATTRIBUTE
  • XmlIndexSpecification::NODE_METADATA

  Note that if XmlIndexSpecification::NODE_METADATA is used, then XmlIndexSpecification::PATH_NODE must also be used as well.

  To identify the key type, use one of the following:

  • XmlIndexSpecification::KEY_PRESENCE
  • XmlIndexSpecification::KEY_EQUALITY
  • XmlIndexSpecification::KEY_SUBSTRING

  For example:

  XmlIndexSpecification::PATH_NODE | XmlIndexSpecification::NODE_ELEMENT | XmlIndexSpecification::KEY_SUBSTRING

• Identifies the type of information being indexed. The value must be one of the XmlValue enumerated types:

  • XmlValue::NONE
  • XmlValue::BASE_64_BINARY
  • XmlValue::BOOLEAN
  • XmlValue::DATE
  • XmlValue::DATE_TIME
  • XmlValue::DECIMAL
  • XmlValue::DOUBLE
  • XmlValue::DURATION
  • XmlValue::FLOAT
  • XmlValue::G_DAY
  • XmlValue::G_MONTH
  • XmlValue::G_MONTH_DAY
  • XmlValue::G_YEAR
  • XmlValue::G_YEAR_MONTH
  • XmlValue::HEX_BINARY
  • XmlValue::STRING
  • XmlValue::TIME

  Note that if XmlIndexSpecification::KEY_PRESENCE is specified for type, then this parameter must be XmlValue::NONE.

The XmlIndexSpecification::deleteIndex method may fail and throw XmlException, encapsulating one of the following non-zero errors:

• Unknown index specification
