public interface Dynamic
extends BuiltInDataType
```
A DataType class that must compute its length based upon actual data. This type may be referred to directly within a listing (including pointers). This type may only appear within a structure if canSpecifyLength() returns true. A pointer to this type can always appear within a structure. TypeDef to this data-type should not be allowed.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`canSpecifyLength()`	Returns true if a user-specified length can be used
`int`	`getLength(MemBuffer buf, int maxLength)`	Compute the length for this data-type which corresponds to the specified memory location.
`DataType`	`getReplacementBaseType()`	Returns a suitable replacement base data-type for pointers and arrays when exporting to C code

- Method Detail
  - getLength
```
int getLength(MemBuffer buf,
              int maxLength)
```
    Compute the length for this data-type which corresponds to the specified memory location.
    
    Parameters:
    
    buf - memory location
    
    maxLength - maximum number of bytes to consume in computing length, or -1 for unspecified.
    
    Returns:
    
    data length or -1 if it could not be determined. Returned length may exceed maxLength if data-type does not supported constrained lengths.
  - canSpecifyLength
```
boolean canSpecifyLength()
```
    Returns true if a user-specified length can be used
  - getReplacementBaseType
```
DataType getReplacementBaseType()
```
    Returns a suitable replacement base data-type for pointers and arrays when exporting to C code
    
    Returns:
    
    suitable base data-type for this Dynamic data-type
