public StatisticalDigestType(String name,
                             Type type)

Method Detail

appendTo

public void appendTo(Block block,
                     int position,
                     BlockBuilder blockBuilder)

Description copied from interface: Type

Append the value at position in block to blockBuilder.

getSlice

public io.airlift.slice.Slice getSlice(Block block,
                                       int position)

Description copied from interface: Type

Gets the value at the block position as a Slice.

Specified by:

getSlice in interface Type

Overrides:

getSlice in class AbstractType

writeSlice

public void writeSlice(BlockBuilder blockBuilder,
                       io.airlift.slice.Slice value)

Description copied from interface: Type

Writes the Slice value into the BlockBuilder.

Specified by:

writeSlice in interface Type

Overrides:

writeSlice in class AbstractType

writeSlice

public void writeSlice(BlockBuilder blockBuilder,
                       io.airlift.slice.Slice value,
                       int offset,
                       int length)

Description copied from interface: Type

Writes the Slice value into the BlockBuilder.

Specified by:

writeSlice in interface Type

Overrides:

writeSlice in class AbstractType

getObjectValue

public Object getObjectValue(SqlFunctionProperties properties,
                             Block block,
                             int position)

Description copied from interface: Type

Gets an object representation of the type value in the block position. This is the value returned to the user via the REST endpoint and therefore must be JSON serializable.

getTypeParameters

public List<Type> getTypeParameters()

Description copied from interface: Type

For parameterized types returns the list of parameters.

Specified by:

getTypeParameters in interface Type

Overrides:

getTypeParameters in class AbstractType
