Class BinaryArrayData

java.lang.Object

org.apache.flink.table.data.binary.BinarySection

org.apache.flink.table.data.binary.BinaryArrayData

All Implemented Interfaces:

ArrayData, BinaryFormat, TypedSetters

@Internal
public final class BinaryArrayData
extends BinarySection
implements ArrayData, TypedSetters

A binary implementation of ArrayData which is backed by MemorySegments.

For fields that hold fixed-length primitive types, such as long, double or int, they are stored compacted in bytes, just like the original java array.

The binary layout of BinaryArrayData:

 [size(int)] + [null bits(4-byte word boundaries)] + [values or offset&length] + [variable length part].

Note: Precision is compact: can call TypedSetters.setNullAt(int) when decimal is null. Precision is not compact: can not call TypedSetters.setNullAt(int) when decimal is null, must call setDecimal(pos, null, precision) because we need update var-length-part.

Set Timestamp value.

Note: If precision is compact: can call TypedSetters.setNullAt(int) when TimestampData value is null. Otherwise: can not call TypedSetters.setNullAt(int) when TimestampData value is null, must call setTimestamp(pos, null, precision) because we need to update var-length-part.
