Extensions.ExternalServiceProvider.PropertyFlag

Classification

Name	PropertyFlag
Short Description	Characteristics of values that access rights used in the ServiceProviderSignatures Properties
Class	Simple Data Type
Base Data Type	SimpleType
Default Value	READ-ONLY
Provide a Literal	Yes
SpecifiedBy	ISO 13209-4
Standard Compliant	Yes

Description

PropertyFlags is an enumeration type describing access rights used in the ServiceProviderSignatures Properties.

The list of allowed enumeration values is defined as follows:

Value	Literal	Description
READ-ONLY	@PropertyFlag:READ-ONLY	The property value, defined in PropertySignature, is read only. This is the default access right if the <init> of the PropertyFlags variable is not defined.
WRITE-ONLY	@PropertyFlag:WRITE-ONLY	The property value, defined in PropertySignature, is only writable.
READ-WRITE	@PropertyFlag:READ-WRITE	The property value, defined in PropertySignature, is readable as well writable.

Order Relation

PropertyFlags values may occur as operands of comparisons (cf. Part 2 of ISO 13209, relational operations). For this case, the following order relation will apply:

READ-ONLY < WRITE-ONLY < READ-WRITE

Literal

The syntax for Literals for complex data types will be used, where the member value is one of the values in the list.

@PropertyFlag:READ-ONLY|WRITE-ONLY|READ-WRITE

Core Conversion

The following table shows the rules for conversion to another data type:

Conversion	Result	Sample
ToBoolean	Undefined (should not be used)
ToInteger	Return the index of the value in the PropertyFlags enumeration (smallest index is 0)	Integer val = ToInteger(@PropertyFlag:READ-WRITE); // Returns 2
ToFloat	Undefined (should not be used)
ToString	Resulting string will be the name of the enumeration value	String s = ToString(@PropertyFlag:READ-WRITE); // Returns "READ-WRITE"
ToByteField	Undefined (should not be used)

Sample

ExternalServiceProvider.PropertyFlag PropertyFlag1 = @PropertyFlag:READ-ONLY;
