Field Detail

SMALLINT

public static final SmallintType SMALLINT

Method Detail

getFixedSize

public 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 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

createBlockBuilder

public BlockBuilder createBlockBuilder(BlockBuilderStatus blockBuilderStatus,
                                       int expectedEntries)

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 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

isComparable

public boolean isComparable()

Description copied from interface: Type

True if the type supports equalTo and hash.

Specified by:

isComparable in interface Type

Overrides:

isComparable in class AbstractType

isOrderable

public boolean isOrderable()

Description copied from interface: Type

True if the type supports compareTo.

Specified by:

isOrderable in interface Type

Overrides:

isOrderable 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.

Specified by:

getObjectValue in interface Type

equalTo

public boolean equalTo(Block leftBlock,
                       int leftPosition,
                       Block rightBlock,
                       int rightPosition)

Description copied from interface: Type

Are the values in the specified blocks at the specified positions equal?

This method assumes input is not null.

Specified by:

equalTo in interface Type

Overrides:

equalTo in class AbstractType

hash

public long hash(Block block,
                 int position)

Description copied from interface: Type

Calculates the hash code of the value at the specified position in the specified block.

Specified by:

hash in interface Type

Overrides:

hash in class AbstractType

compareTo

public int compareTo(Block leftBlock,
                     int leftPosition,
