Class IndexName

java.lang.Object

org.apache.jackrabbit.oak.plugins.index.IndexName

All Implemented Interfaces:

Comparable<IndexName>

public class IndexName
extends Object
implements Comparable<IndexName>

An index name, which possibly contains two version numbers: the product version number, and the customer version number. The format of an index node name is: - The name of the index, - optionally a dash ('-') and the product version number, - optionally "-custom-" and the customer version number. If the node name doesn't contain version numbers / dashes, then version 0 is assumed (for both the product version number and customer version number).

Method Detail

parse

public static IndexName parse(String nodeName)

Parse the node name. Both node names with version and without version are supported.

Parameters:

nodeName - the node name (starting from root; e.g. "/oak:index/lucene")

Returns:

the index name object

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(IndexName o)

Specified by:

compareTo in interface Comparable<IndexName>

getLatestCustomized

public IndexName getLatestCustomized(List<IndexName> all)

Get the latest index name object that matches this index base name, and is customized.

Parameters:

all - the list of all indexes

Returns:

the lastest customized index, or null if none

getLatestProduct

public IndexName getLatestProduct(List<IndexName> all)

Get the latest product index that matches this index base name.

Parameters:

all - the list of all indexes

Returns:

the latest product index, or null if none

filterReplacedIndexes

public static Collection<String> filterReplacedIndexes(Collection<String> indexPaths,
                                                       NodeState rootState,
                                                       boolean checkIsActive)

Filter out index that are replaced by another index with the same base name but newer version. Indexes without a version number in the name are always used, except if there is an active index with the same base name but a newer version. Active indexes have a hidden ":oak:mount-" node, which means they are indexed in the read-only node store.

Parameters:

indexPaths - the set of index paths

rootState - the root node state (used to find hidden nodes)

Returns:

the filtered list

nextCustomizedName

public String nextCustomizedName()

isIndexActive

                                    NodeState rootState)

getNodeName

public String getNodeName()

getCustomerVersion

public int getCustomerVersion()

getProductVersion

public int getProductVersion()

getBaseName

public String getBaseName()

isVersioned

public boolean isVersioned()

isLegal
