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.

Method Summary

Modifier and Type	Method	Description
default boolean	canSpecifyLength()	Determine if the length may be specified for an instanceof this datatype (e.g., Data, Array, DataTypeComponent, etc.).
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

default boolean canSpecifyLength()

Determine if the length may be specified for an instanceof this datatype (e.g., Data, Array, DataTypeComponent, etc.).

Returns:

true if a user-specified length can be used, else false

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
