IMPORT_C TInt | operator[](TInt) |
Holds the values of a predefined set of attributes based upon ContentAccess::TStringAttribute
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
IMPORT_C void | AddL | ( | TInt | aAttribute | ) |
Add a new attribute to the set The attribute value is initalised with an empty string
Parameter | Description |
---|---|
aAttribute | The attribute to add to the set |
IMPORT_C void | Close | ( | ) |
Release all resources used by the RStringAttributeSet
This must be called before the RStringAttribute set goes out of scope
IMPORT_C TInt | Count | ( | ) | const |
The number of attributes in the set
Returns: The number of attributes in the set
IMPORT_C void | ExternalizeL | ( | RWriteStream & | aStream | ) | const |
Write the RAttributeSet to a stream
Parameter | Description |
---|---|
aStream | The stream to write the attribute set to |
Get the value of a specified attribute
Parameter | Description |
---|---|
aAttribute | The attribute to query |
aValue | The value of the attribute is copied to this descriptor |
Returns: The value of the attribute KErrOverflow If the descriptor is not large enough to store the attribute KErrNotFound if 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.
Parameter | Description |
---|---|
aStream | The stream to read the attribute set from |

aAttribute | The attribute to set |
aValue | The value of the attribute |
aErrorCode | The error to return when GetValue() is called for this attribute |
