DataType

java.lang.Object
- java.lang.Enum<DataType>
- - org.apache.hawq.pxf.api.io.DataType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<DataType>
```
public enum DataType
extends java.lang.Enum<DataType>
```
Supported Data Types and OIDs (HAWQ Data Type identifiers). There's a one-to-one match between a Data Type and it's corresponding OID.

```
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
  - get
```
public static DataType get(int OID)
```
    Utility method for converting an OID to a DataType(int).
    
    Parameters:
    
    OID - the oid to be converted
    
    Returns:
    
    the corresponding DataType if exists, else returns UNSUPPORTED_TYPE
  - getOID
```
public int getOID()
```
