Method Detail

getUniqueKey

public String getUniqueKey()

Returns the unique key attribute configured in this index config. Defaults to __key. The unique key attribute is used as a source of values which uniquely identify each entry being inserted into an index.

Returns:

the configured unique key attribute.

setUniqueKey

public BitmapIndexOptions setUniqueKey(@Nonnull
                                       String uniqueKey)

Sets unique key attribute in this index config.

Parameters:

uniqueKey - a unique key attribute to configure.

getUniqueKeyTransformation

public BitmapIndexOptions.UniqueKeyTransformation getUniqueKeyTransformation()

Returns the unique key transformation configured in this index. Defaults to OBJECT. The transformation is applied to every value extracted from unique key attribue.

Returns:

the configured unique key transformation.

setUniqueKeyTransformation

public BitmapIndexOptions setUniqueKeyTransformation(@Nonnull
                                                     BitmapIndexOptions.UniqueKeyTransformation uniqueKeyTransformation)

Sets unique key transformation in this index config.

Parameters:

uniqueKeyTransformation - a unique key transformation to configure.

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.

getFactoryId
