- Method Detail
  - values
```
public static DataType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (DataType c : DataType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static DataType valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - createFromJavaType
```
public static DataType createFromJavaType(java.lang.String javaType)

    Returns:
    
    the datatype, null if no such type
  - isPrimitive
```
public boolean isPrimitive()
```
    Returns whether type is a primitive.
    
    Returns:
    
    true if primitive
  - isMutable
```
public boolean isMutable()
```
    Returns whether type is a mutable java object.
    Mutable objects may change their state and must implement Freezable.
    
    Returns:
    
    true if mutable and freezable
  - isNumeric
```
public boolean isNumeric()
```
    Returns whether this is a numeric type.

```
public boolean isBool()
```
    Returns whether this is a boolean or Boolean type.
    
    Returns:
    
    true if bool
  - getSqlTypes
```
public org.tentackle.sql.SqlType[] getSqlTypes()
```
    Gets the sql type.
    Notice that a tentackle type may be mapped to more than one column for multi-column types such as BMoney.
    
    Returns:
    
    the sql type(s)
  - getSqlTypesWithPostfix
```
public DataType.SqlTypeWithPostfix[] getSqlTypesWithPostfix()
```
    Gets the SqlTypes along with their column name postfixes.
    The first postfix is always the empty string. The second one is "_2", third "_3" and so on. This is a tentackle convention for multi-column types such as BMoney.
    
    Returns:
    
    the sq; types and their postfixes
  - isMultiColumn
```
public boolean isMultiColumn()
```
    True if this is a multicolumn type.
    
    Returns:
    
    true if multicolumn
  - isScaleInSecondColumn
```
public boolean isScaleInSecondColumn()
```
    Returns whether this is a numeric type with the scale stored in a second column.
    BMoney and Dmoney for example.
    
    Returns:
    
    true if scale in second column
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Enum<DataType>
  - toPrimitive
```
public DataType toPrimitive()
```
    Converts to a Java primitive.
    
    Returns:
    
    the primitive type, never null
  - toNonPrimitive
```
public DataType toNonPrimitive()
```
    Converts a primitive to a Java class.
    
    Returns:
    
    the non-primitive type, never null
  - parse
```
public java.lang.Object parse(java.lang.String str)
```
    Parses a string and converts to the value of this type.
    Notice: the method doesn't use any locale, so the results are always the same regardless of the JVM's locale.
    
    Parameters:
    
    str - the source string
    
    Returns:
    
    the value
  - print
```
public java.lang.String print(java.lang.Object object)
```
    Takes an object and converts it to a string that can in turn be parsed with parse(java.lang.String).
    
    Parameters:
    
    object - the object of this DataType
    
    Returns:
    
    the printable string
