Method Detail

getFixedSize

int getFixedSize()

Gets the size of a value of this type is bytes. All values of a FixedWidthType are the same size.

createFixedSizeBlockBuilder

BlockBuilder createFixedSizeBlockBuilder(int positionCount)

Creates a block builder for this type sized to hold the specified number of positions.

getObjectValue

Object getObjectValue(ConnectorSession session,
                    io.airlift.slice.Slice slice,
                    int offset)

Gets an object representation of the type encoded in the specified slice at the specified offset. This is the value returned to the user via the REST endpoint and therefore must be JSON serializable.

getBoolean

boolean getBoolean(io.airlift.slice.Slice slice,
                 int offset)

Gets the value at the specified offset in the specified slice as a boolean.

writeBoolean

void writeBoolean(io.airlift.slice.SliceOutput sliceOutput,
                boolean value)

Writes the boolean value into the specified slice output.

getLong

long getLong(io.airlift.slice.Slice slice,
           int offset)

Gets the value at the specified offset in the specified slice as a long.

writeLong

void writeLong(io.airlift.slice.SliceOutput sliceOutput,
             long value)

Writes the long value into the specified slice output.

getDouble

double getDouble(io.airlift.slice.Slice slice,
               int offset)

Gets the value at the specified offset in the specified slice as a double.

writeDouble

void writeDouble(io.airlift.slice.SliceOutput sliceOutput,
               double value)

Writes the double value into the specified slice output.

getSlice

io.airlift.slice.Slice getSlice(io.airlift.slice.Slice slice,
                              int offset)

Gets the value at the specified offset in the specified slice as a Slice.

writeSlice

void writeSlice(io.airlift.slice.SliceOutput sliceOutput,
              io.airlift.slice.Slice value,
              int offset)

Writes the Slice value into the specified slice output.

equalTo

boolean equalTo(io.airlift.slice.Slice leftSlice,
              int leftOffset,
              io.airlift.slice.Slice rightSlice,
              int rightOffset)

Are the values in the specified slices at the specified offsets equal?

equalTo

boolean equalTo(io.airlift.slice.Slice leftSlice,
              int leftOffset,
              BlockCursor rightCursor)

Is the value at the specified offset in the specified slice equal value at the specified cursor?

hash

int hash(io.airlift.slice.Slice slice,
       int offset)

compareTo

int compareTo(io.airlift.slice.Slice leftSlice,
            int leftOffset,
            io.airlift.slice.Slice rightSlice,
            int rightOffset)

Compare the values in the specified slices at the specified offsets equal.

appendTo

void appendTo(io.airlift.slice.Slice slice,
            int offset,
            BlockBuilder blockBuilder)

Append the value at offset in slice to blockBuilder.

appendTo

void appendTo(io.airlift.slice.Slice slice,
