Access Operators
Access operators refer to members of a Struct or operations of an object. They enable to you to query and assign values to Struct members and activate operations using object handles.
Access operations have the highest priority and take precedence over all other operators.
| Operator | Symbol | Description |
|---|---|---|
| Struct index | {N} | Returns a reference to a single member of a Struct based on its index position in the collection of references. Can be used with the member list or dereference operators. |
| Struct member list | ->* | Returns a collection of references to all members of a Struct. |
| Struct dereference | -> | Returns a collection of references to all Struct members with the specified name. |
| Operation activation | -> | Activates an operation via a handle |
Accessing Struct Members
Assign the value of the
account_id member of the data referenced by structvStruct:
vAccount = vStruct->account_id
Extract the value of the second occurrence of the
member with name phone_number, where multiple members have the same name :
vMobile = vStruct->phone_number[2]
Activating Component Operations
Create an instance of component and assign it to a
handle, then call the setDisplay operation, passing it the value of the SIZE field
as parameter.
