FieldType (Apache Geode 1.15.1)

java.lang.Object
- java.lang.Enum<FieldType>
- - org.apache.geode.pdx.FieldType

All Implemented Interfaces:

Serializable, Comparable<FieldType>
```
public enum FieldType
extends Enum<FieldType>
```
Every field of a pdx must have one of these types. The type of that field can never change. If you do want to be able to change a field's class then its field type needs to be OBJECT. Some field types are always serialized with a certain number of bytes; these are called "fixed-width". Others are serialized with a variable number of bytes; these are called "variable-width".

Since:

GemFire 6.6.2

- Method Detail
  - values
```
public static FieldType[] 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 (FieldType c : FieldType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static FieldType 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
  - isFixedWidth
```
public boolean isFixedWidth()
```
    Returns:
    
    true if the type is "fixed-width"; false if it is "variable-width".
  - getWidth
```
public int getWidth()
```
    Returns:
    
    the number of bytes used to serialize fixed-width fields; -1 is returned for variable-width fields.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Enum<FieldType>
  - getDefaultBytes
```
public ByteBuffer getDefaultBytes()
```
    Returns:
    
    a ByteBuffer that contains the serialized encoding of this type's default value.
  - get
```
public static FieldType get(Class<?> c)
```
    Given a Class return the corresponding FieldType.
    
    Parameters:
    
    c - a Class
    
    Returns:
    
    the FieldType corresponding to the given Class
  - getDefaultValue
```
public Object getDefaultValue()
```
