方法

getKind()

Gets index kind.
Hash(DataType dataType)

Returns an instance of HashIndex class with specified DataType.

Here is an example to create HashIndex instance passing in the DataType: 

HashIndex hashIndex = Index.Hash(DataType.String);

</code></pre></p>
Hash(DataType dataType, int precision)

Returns an instance of HashIndex class with specified DataType and precision.

Here is an example to create HashIndex instance passing in the DataType and precision:

HashIndex hashIndex = Index.Hash(DataType.String, 3);
Range(DataType dataType)

Returns an instance of RangeIndex class with specified DataType.

Here is an example to create RangeIndex instance passing in the DataType: 

RangeIndex rangeIndex = Index.Range(DataType.Number);

</code></pre></p>
Range(DataType dataType, int precision)

Returns an instance of RangeIndex class with specified DataType and precision.

Here is an example to create RangeIndex instance passing in the DataType and precision: 

RangeIndex rangeIndex = Index.Range(DataType.Number, -1);

</code></pre></p>
Spatial(DataType dataType)

Returns an instance of SpatialIndex class with specified DataType.

Here is an example to create SpatialIndex instance passing in the DataType:

SpatialIndex spatialIndex = Index.Spatial(DataType.Point);
