Class NestedRowData

java.lang.Object
org.apache.flink.table.data.binary.BinarySection
org.apache.flink.table.data.binary.NestedRowData
All Implemented Interfaces:
BinaryFormat, TypedSetters, RowData

@Internal public final class NestedRowData extends BinarySection implements RowData, TypedSetters
Its memory storage structure is exactly the same with BinaryRowData. The only different is that, as NestedRowData is used to store row value in the variable-length part of BinaryRowData, every field (including both fixed-length part and variable-length part) of NestedRowData has a possibility to cross the boundary of a segment, while the fixed-length part of BinaryRowData must fit into its first memory segment.

    • getArity

      public int getArity()
      Description copied from interface: RowData
      Returns the number of fields in this row.

      The number does not include RowKind. It is kept separately.

      Specified by:
      getArity in interface RowData
    • getRowKind

      public org.apache.flink.types.RowKind getRowKind()
      Description copied from interface: RowData
      Returns the kind of change that this row describes in a changelog.
      Specified by:
      getRowKind in interface RowData

      • RowKind
    • setRowKind

      public void setRowKind(org.apache.flink.types.RowKind kind)
      Description copied from interface: RowData
      Sets the kind of change that this row describes in a changelog.

    • setNullAt

      public void setNullAt(int i)
      Specified by:

    • setInt

      public void setInt(int pos, int value)
      Specified by:
      setInt in interface TypedSetters
    • setLong

      public void setLong(int pos, long value)
      Specified by:

    • setDouble

      public void setDouble(int pos, double value)
      Specified by:
      setDouble in interface TypedSetters
    • setDecimal

      public void setDecimal(int pos, DecimalData value, int precision)
      Description copied from interface: TypedSetters
      Set the decimal column value.

      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.

      Specified by:
      setDecimal in interface TypedSetters
    • setTimestamp

      public void setTimestamp(int pos, TimestampData value, int precision)
      Description copied from interface: TypedSetters
      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.
