Method Detail

getFixedSize

public final int getFixedSize()

Description copied from interface: FixedWidthType

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

Specified by:

getFixedSize in interface FixedWidthType

createBlockBuilder

public final BlockBuilder createBlockBuilder(BlockBuilderStatus blockBuilderStatus,
                                             int expectedEntries,
                                             int expectedBytesPerEntry)

Description copied from interface: Type

Creates the preferred 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

createFixedSizeBlockBuilder

public final BlockBuilder createFixedSizeBlockBuilder(int positionCount)

Description copied from interface: FixedWidthType

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

Specified by:

createFixedSizeBlockBuilder in interface FixedWidthType

getSlice

public final 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:
