Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.lang.String`	`getTypeName()`	name of variable type (limited to 100 characters length)
`java.lang.Object`	`getValue(ValueFields valueFields)`
`boolean`	`isAbleToStore(java.lang.Object value)`
`boolean`	`isCachable()`	Indicates if this variable type supports caching.
`void`	`setValue(java.lang.Object value, ValueFields valueFields)`	Stores the specified value in the supplied `ValueFields`.

- Method Detail
  - getTypeName
```
java.lang.String getTypeName()
```
    name of variable type (limited to 100 characters length)
  - isCachable
```
boolean isCachable()
```
    Indicates if this variable type supports caching.
    
    If caching is supported, the result of getValue(ValueFields) is saved for the duration of the session and used for subsequent reads of the variable's value.
    
    If caching is not supported, all reads of a variable's value require a fresh call to getValue(ValueFields).
    
    Returns:
    
    whether variables of this type are cacheable.
  - isAbleToStore
```
boolean isAbleToStore(java.lang.Object value)
```
    Returns:
    
    whether this variable type can store the specified value.
  - setValue
```
void setValue(java.lang.Object value,
              ValueFields valueFields)
```
    Stores the specified value in the supplied ValueFields.
  - getValue
```
java.lang.Object getValue(ValueFields valueFields)
```
    Returns:
    
    the value of a variable based on the specified ValueFields.
