public interface IndexAbstraction
An index abstraction is a reference to one or more concrete indices.
An index abstraction has a unique name and encapsulates all the
IndexMetadata
instances it is pointing to.
Also depending on type it may refer to a single or many concrete indices and may or may not have a write index.-

Method Summary
-
Method Details
-
getType
IndexAbstraction.Type getType()- Returns:
- the type of the index abstraction
-
getName
String getName()- Returns:
- the name of the index abstraction
-
getIndices
- Returns:
- All
IndexMetadata
of all concrete indices this index abstraction is referring to.
-
getWriteIndex
A write index is a dedicated concrete index, that accepts all the new documents that belong to an index abstraction.A write index may also be a regular concrete index of a index abstraction and may therefore also be returned by
getIndices()
. An index abstraction may also not have a dedicated write index.- Returns:
- the write index of this index abstraction or
null
if this index abstraction doesn't have a write index.
-
getParentDataStream
- Returns:
- the data stream to which this index belongs or
null
if this is not a concrete index or if it is a concrete index that does not belong to a data stream.
-
isHidden
boolean isHidden()- Returns:
- whether this index abstraction is hidden or not
-
isSystem
boolean isSystem()- Returns:
- whether this index abstraction should be treated as a system index or not
-
isDataStreamRelated
default boolean isDataStreamRelated()- Returns:
- whether this index abstraction is related to data streams
-
getAliases
- Returns:
- the names of aliases referring to this instance.
Returns
null
if aliases can't point to this instance.
