FAST

public static final S2TaggedShapeCoder FAST

An instance of a S2TaggedShapeCoder which encodes/decodes S2Shapes in the FAST encoding format. The FAST format is optimized for fast encoding/decoding.

COMPACT

public static final S2TaggedShapeCoder COMPACT

An instance of a S2TaggedShapeCoder which encodes/decodes S2Shapes in the COMPACT encoding format. The COMPACT format is optimized for disk usage and memory footprint.

Method Details

encode

public void encode(S2Shape value,
 OutputStream output)
            throws IOException

Description copied from interface: S2Coder

Encodes value to output.

Specified by:

encode in interface S2Coder<S2Shape>

Throws:

IOException

decode

public S2Shape decode(PrimitiveArrays.Bytes data,
 PrimitiveArrays.Cursor cursor)

Description copied from interface: S2Coder

Decodes a value of type S2Coder from data starting at cursor.position. cursor.position is updated to the position of the first byte in data following the encoded value.

Specified by:

decode in interface S2Coder<S2Shape>

builder

public static S2TaggedShapeCoder.Builder builder()

Returns a new S2TaggedShapeCoder.Builder.

toBuilder

public S2TaggedShapeCoder.Builder toBuilder()

Returns a new S2TaggedShapeCoder.Builder initialized with the current S2TaggedShapeCoder.
