Method Details

getName

public String getName()

Specified by:

getName in interface IndexAbstraction

Returns:

the name of the index abstraction

getType

public IndexAbstraction.Type getType()

Specified by:

getType in interface IndexAbstraction

Returns:

the type of the index abstraction

getIndices

public List<IndexMetadata> getIndices()

Specified by:

getIndices in interface IndexAbstraction

Returns:

All IndexMetadata of all concrete indices this index abstraction is referring to.

getWriteIndex

public IndexMetadata getWriteIndex()

Description copied from interface: IndexAbstraction

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 IndexAbstraction.getIndices(). An index abstraction may also not have a dedicated write index.

Specified by:

getWriteIndex in interface IndexAbstraction

Returns:

the write index of this index abstraction or null if this index abstraction doesn't have a write index.

getParentDataStream

public IndexAbstraction.DataStream getParentDataStream()

Specified by:

getParentDataStream in interface IndexAbstraction

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

public boolean isHidden()

Specified by:

isHidden in interface IndexAbstraction

Returns:

whether this index abstraction is hidden or not

isSystem

public boolean isSystem()

Specified by:

isSystem in interface IndexAbstraction

Returns:

whether this index abstraction should be treated as a system index or not

getDataStream

public DataStream getDataStream()
