GenericRow (Paimon : 1.0-SNAPSHOT API)

java.lang.Object
- org.apache.paimon.data.GenericRow

All Implemented Interfaces:

Serializable, DataGetters, InternalRow
```
@Public
public final class GenericRow
extends Object
implements InternalRow, Serializable
```
An internal data structure representing data of RowType.
GenericRow is a generic implementation of InternalRow which is backed by an array of Java Object. A GenericRow can have an arbitrary number of fields of different types. The fields in a row can be accessed by position (0-based) using either the generic getField(int) or type-specific getters (such as getInt(int)). A field can be updated by the generic setField(int, Object).
Note: All fields of this data structure must be internal data structures. See InternalRow for more information about internal data structures.
The fields in GenericRow can be null for representing nullability.

Since:

0.4.0

- Constructor Detail
  - GenericRow
```
public GenericRow(RowKind kind,
                  int arity)
```
    Creates an instance of GenericRow with given kind and number of fields.
    Initially, all fields are set to null.
    Note: All fields of the row must be internal data structures.
    
    Parameters:
    
    kind - kind of change that this row describes in a changelog
    
    arity - number of fields
  - GenericRow
```
public GenericRow(int arity)
```
    Creates an instance of GenericRow with given number of fields.
    Initially, all fields are set to null. By default, the row describes a RowKind.INSERT in a changelog.
    Note: All fields of the row must be internal data structures.
    
    Parameters:
    
    arity - number of fields
- Method Detail
  - setField
```
public void setField(int pos,
                     Object value)
```
    Sets the field value at the given position.
    Note: The given field value must be an internal data structures. Otherwise the GenericRow is corrupted and may throw exception when processing. See InternalRow for more information about internal data structures.
    The field value can be null for representing nullability.
  - getField
```
public Object getField(int pos)
```
    Returns the field value at the given position.
    Note: The returned value is in internal data structure. See InternalRow for more information about internal data structures.
