isNullable
Description copied from interface:DataType
Indicates whether this instance supports encoding null values. This depends on the implementation details of the encoding format. AllDataType
s that support null should treat null as comparing less than any non-null value for default sort ordering purposes.- Specified by:
isNullable
in interfaceDataType<Float>
- Overrides:
isNullable
in classOrderedBytesBase<Float>
- Returns:
true
when null is supported,false
otherwise.
-
encodedLength
Description copied from interface:DataType
Inform consumers how long the encodedbyte[]
will be.- Parameters:
val
- The value to check.- Returns:
- the number of bytes required to encode
val
.a
-
encodedClass
Description copied from interface:DataType
Inform consumers over what type thisDataType
operates. Useful when working with bareDataType
instances. -
decode
Description copied from interface:DataType
Read an instance ofT
from the buffersrc
.- Parameters:
src
- the buffer containing the encoded value.
-
encode
Description copied from interface:DataType
Write instanceval
into bufferdst
.- Parameters:
dst
- the buffer containing the encoded value.val
- the value to encode ontodst
.- Returns:
- number of bytes written.
-
decodeFloat
Read afloat
value from the bufferdst
