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
- id
```
public int id()
```
  A reliable unique identifier for this type.
- getJavaType
```
public JavaType getJavaType()
```
  Gets the JavaType for this field. For lists, this identifies the type of the elements contained within the list.
- isPacked
```
public boolean isPacked()
```
  Indicates whether a list field should be represented on the wire in packed form.
- isPrimitiveScalar
```
public boolean isPrimitiveScalar()
```
  Indicates whether this field type represents a primitive scalar value. If this is true, then isScalar() will also be true.
- isScalar
```
public boolean isScalar()
```
  Indicates whether this field type represents a scalar value.
- isList
```
public boolean isList()
```
  Indicates whether this field represents a list of values.
- isMap
```
public boolean isMap()
```
  Indicates whether this field represents a map.
- isValidForField
```
public boolean isValidForField(Field field)
```
  Indicates whether or not this FieldType can be applied to the given Field.
- forId
```
public static FieldType forId(int id)
```
  Looks up the appropriate FieldType by it's identifier.
  
  Returns:
  
  the FieldType or null if not found.
