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(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:
  
  IllegalArgumentException - if this enum type has no constant with the specified name
  
  NullPointerException - if the argument is null
- from
```
public static DataType from(String value)
```
  Replacement of valueOf(String).
  
  Parameters:
  
  value - case-insensitive string representation of the data type
  
  Returns:
  
  data type
- getLength
```
public int getLength()
```
  Get length in byte.
  
  Returns:
  
  length in byte, zero stands for unlimited
- getPrecision
```
public int getPrecision()
```
- getScale
```
public int getScale()
```
