Enum Objects — Their Methods and Properties

When you create an object that accesses an enumerated symbol in your source code, the object constructor createobj returns an enum object. createobj uses the information in your source code to set the properties of the object appropriately to match the code. Within the properties and their values you find all the information about the symbol, so that MATLAB understands how to handle the symbol in your MATLAB workspace.

To add to the properties of the enum class, enum objects inherit properties and methods from the numeric and memoryobj classes.

Properties of Enum Objects

Object properties can include both properties that the object inherits from its superclass, if any, and some properties that are unique to the class itself. For this reason, many objects in Embedded IDE Link CC share common properties; as you use the objects you will become familiar with the common and special properties for each.

Property NameProperty TypeDefault ValueDescription

address

mxArray

[0 0]

Memory address of the symbol, in [Offset Page] format

arrayorder

{col-major,row-major}

row-major

Ordering of values when moving data from linear memory storage to N-D arrays in MATLAB

bitsperstorageunit

double

8

Bits per smallest addressable unit in the signal processor

endianness

{little, big}

little

Specifies whether the data is stored as little endian or big endian data

label

mxArray

N/A

Lists the enumerated labels for the object

link

MATLAB handle

None

Object handle that identifies the object

name

string

None

Name of the embedded symbol in the symbol table

numberofstorageunits

double

1

Number of memory units needed to represent the object

postpad

int

0

Number of bits of padding added at the end of the memory buffer. Added bits are ignored in final numeric values.

prepad

int

0

Number of bits of padding added at the beginning of the memory buffer. Added bits are ignored in final numeric values

represent

{signed, unsigned, float, fract, ufract}

signed

Reports the data type of the values

size

mxArray

1

Specifies the size of the array created in MATLAB from the data received from memory

storageunitspervalue

int

32

Addressable units (au) per value in memory. May be less than one when you use bit packing

timeout

double

10 seconds

Time-out period for link methods

value

mxArray

0

Contains a vector of the enumerated type

Methods of Enum Objects

Like properties, methods for objects may come from the superclass or derive only from the class itself. For example, the cast and convert methods do not appear in all objects; listing them here indicates that the object does not inherit these methods but provides them itself.

display

Yes

Display the properties of the object

equivalent

No

Return the equivalent string or numeric value based on the input argument
