| class ContentAccess::RAttributeSet |
Holds the values of a predefined set of attributes based upon ContentAccess::TAttribute
It is also possible for an agent to provide an extended set of these attributes beyond EAgentSpecificAttributeBase but only applications written to support that particular agent will support this.
No duplicate attributes are allowed in the set

| RArray< TAttributeValue > | iAttributes |
| IMPORT_C void | AddL | ( | TInt | aAttribute | ) |
Add a new attribute to the set The attribute is initalised with a default value of EAttributeNotSupported
| TInt aAttribute | The attribute to add to the set |
| IMPORT_C void | Close | ( | ) |
Release all resources used by the RAttributeSet
This must be called before the RAttribute set goes out of scope
| IMPORT_C TInt | Count | ( | ) | const |
The number of attributes in the set The number of attributes in the set
| IMPORT_C void | ExternalizeL | ( | RWriteStream & | aStream | ) | const |
Write the RAttributeSet to a stream
| RWriteStream & aStream | The stream to write the attribute set to |
| IMPORT_C TInt | GetValue | ( | TInt | aAttribute, |
| TInt & | aValue | |||
| ) | const | |||
Get the value of a specified attribute Whether the value parameter was updated
KErrNone The attribute value was updated
KErrNotFound The attribute is not part of the set
| IMPORT_C void | InternalizeL | ( | RReadStream & | aStream | ) |
Read the RAttributeSet from a stream This does not clear the contents of the attribute set before reading. The values of any attributes already in the set are updated with new values from the stream. New attributes from the stream and their values are added to the set.
| RReadStream & aStream | The stream to read the attribute set from |
| IMPORT_C TInt | SetValue | ( | TInt | aAttribute, |
| TInt | aValue, | |||
| TInt | aErrorCode | |||
| ) | ||||
Set the value of an attribute within the set Whether the new attribute value was set
KErrNone if the value was set
KErrNotFound if the attribute is not part of the set
| IMPORT_C TInt | operator[] | ( | TInt | aIndex | ) | const |
Find the attribute stored at a particular index in the set The attribute, NOT the value of the attribute
| TInt aIndex | The index of the attribute |
