nsIRDFContainer

IID:D4214E90-FB94-11D2-BDD8-00104BDE6048
Inherits From:nsISupports

An object of this interface should be created in the following way:

RDFContainerUtils.MakeSeq(resource)

This interface is implemented by the following components:

Properties

readonly nsIRDFDataSource DataSource

readonly nsIRDFResource Resource

Methods

void AppendElement ( nsIRDFNode element ) PRInt32 GetCount ( ) nsISimpleEnumerator GetElements ( ) PRInt32 IndexOf ( nsIRDFNode element ) void Init ( nsIRDFDataSource dataSource , nsIRDFResource container ) void InsertElementAt ( nsIRDFNode element , PRInt32 index , PRBool renumber ) void RemoveElement ( nsIRDFNode element , PRBool renumber ) nsIRDFNode RemoveElementAt ( PRInt32 index , PRBool renumber )

void AppendElement ( nsIRDFNode element )

Append an element to the container, assigning it the next available ordinal.

Arguments:
element

PRInt32 GetCount ( )

Return the number of elements in the container. Note that this may not always be accurate due to aggregation.

nsISimpleEnumerator GetElements ( )

Return an enumerator that can be used to enumerate the contents of the container in ascending order.

PRInt32 IndexOf ( nsIRDFNode element )

Determine the index of an element in the container.

Arguments:
element
Returns:
The index of the specified element in the container. If the element is not contained in the container, this function returns '-1'.

void Init ( nsIRDFDataSource dataSource , nsIRDFResource container )

Initialize the container wrapper to the specified resource using the specified datasource for context.

Arguments:
dataSource
container

void InsertElementAt ( nsIRDFNode element , PRInt32 index , PRBool renumber )

Insert element at the specified index. If renumber is 'true', then the underlying RDF graph will be 're-numbered' to accomodate the new element.

Arguments:
element
index
renumber

void RemoveElement ( nsIRDFNode element , PRBool renumber )

Remove the first occurence of the specified element from the container. If renumber is 'true', then the underlying RDF graph will be 're-numbered' to account for the removal.

Arguments:
element
renumber

nsIRDFNode RemoveElementAt ( PRInt32 index , PRBool renumber )

Remove the element at the specified index. If renumber is 'true', then the underlying RDF graph will be 're-numbered' to account for the removal.

Arguments:
index
renumber
Returns:
the element that was removed.
