Field Detail

### columns

    protected ColumnDescriptor[] columns

### converters

    protected ExtendedType[] converters

Constructor Detail

### RowDescriptor

    protected RowDescriptor()

  Creates an empty RowDescriptor. Intended mainly for testing and use by subclasses.

### RowDescriptor

    public RowDescriptor(ColumnDescriptor[] columns,
                         ExtendedType[] converters)

  Creates a fully initialized RowDescriptor.

  Since:
    3.0

### RowDescriptor

    public RowDescriptor(ColumnDescriptor[] columns,
                         ExtendedTypeMap types)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Creates a RowDescriptor for an array of columns.

### RowDescriptor

    public RowDescriptor(ResultSet resultSet,
                         ExtendedTypeMap types)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Creates new RowDescriptor using ResultSet metadata to determine the columns.

### RowDescriptor

    public RowDescriptor(ResultSet resultSet,
                         ExtendedTypeMap types,
                         Map javaTypeOverrides)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Creates new RowDescriptor using ResultSet metadata to determine the columns. Note that if javaTypeOverrides array is null, default JDBC to Java types mapping is used.

Method Detail

### indexTypes

    protected void indexTypes(ExtendedTypeMap types)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Initializes converters for columns.

### initFromResultSet

    protected void initFromResultSet(ResultSet resultSet)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Builds columns list from ResultSet metadata.

### overrideJavaTypes

    protected void overrideJavaTypes(Map overrides)

  Deprecated. since 3.0 use `RowDescriptorBuilder`.

  Overrides Java types of result columns. Keys in the map must correspond to the names of the columns.

### getWidth

    public int getWidth()

  Returns a number of columns in a row.

### getColumns

    public ColumnDescriptor[] getColumns()

  Returns column descriptors.

### getConverters

    public ExtendedType[] getConverters()

  Returns extended types for columns.
