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(ConnectorSession session,
                    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.

createBlockBuilder

public BlockBuilder createBlockBuilder(BlockBuilderStatus blockBuilderStatus)

Description copied from interface: Type

Creates a block builder for this type. This is the builder used to store values after an expression projection within the query.

Specified by:

createBlockBuilder in interface Type

Overrides:

createBlockBuilder in class AbstractVariableWidthType
