void XmlIndexSpecification::replaceDefaultIndex(const std::string &index)

void XmlIndexSpecification::replaceDefaultIndex(Type type, XmlValue::Type syntax)

Description: XmlIndexSpecification::replaceDefaultIndex

Replaces the default indexing strategy for the container. The default index specification is used for all nodes in a document. You can add additional indices for specific document nodes using XmlIndexSpecification::addIndex.

Description: void XmlIndexSpecification::replaceDefaultIndex(const std::string &index)

Identifies one or more indexing strategies to set for the default index. The strategies are identified as a space-separated listing of strings.

Parameters

index

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
• anyURI
• base64Binary
• boolean
• date
• dateTime
• dayTimeDuration
• decimal
• double
• duration
• float
• gDay
• gMonth
• gMonthDay
• gYear
• gYearMonth
• hexBinary
• NOTATION
• QName
• string
• time
• yearMonthDuration
• untypedAtomic

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

Errors

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

UNKNOWN_INDEX

Unknown index specification

Description: void XmlIndexSpecification::replaceDefaultIndex(Type type, XmlValue::Type syntax)

Identifies an indexing strategies to set for the default index.

Parameters

type

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

syntax

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

• XmlValue::NONE
• XmlValue::ANY_URI
• XmlValue::BASE_64_BINARY
• XmlValue::BOOLEAN
• XmlValue::DATE
• XmlValue::DATE_TIME
• XmlValue::DAY_TIME_DURATION
• 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::NOTATION
• XmlValue::QNAME
• XmlValue::STRING
• XmlValue::TIME
• XmlValue::YEAR_MONTH_DURATION
• XmlValue::UNTYPED_ATOMIC
• XmlValue::BINARY

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

Errors

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

UNKNOWN_INDEX

Unknown index specification
