This interface is intended to be used as a service. To create an object implementing this interface: 

var obj = Components.classes["@mozilla.org/rdf/container-utils;1"].
            getService(Components.interfaces.nsIRDFContainerUtils);

This interface is implemented by the following components:

Methods

PRInt32 indexOf ( nsIRDFDataSource dataSource , nsIRDFResource container , nsIRDFNode element ) nsIRDFResource IndexToOrdinalResource ( PRInt32 index ) PRBool IsAlt ( nsIRDFDataSource dataSource , nsIRDFResource resource ) PRBool IsBag ( nsIRDFDataSource dataSource , nsIRDFResource resource ) PRBool IsContainer ( nsIRDFDataSource dataSource , nsIRDFResource resource ) PRBool IsEmpty ( nsIRDFDataSource dataSource , nsIRDFResource resource ) PRBool IsOrdinalProperty ( nsIRDFResource property ) PRBool IsSeq ( nsIRDFDataSource dataSource , nsIRDFResource resource ) nsIRDFContainer MakeAlt ( nsIRDFDataSource dataSource , nsIRDFResource resource ) nsIRDFContainer MakeBag ( nsIRDFDataSource dataSource , nsIRDFResource resource ) nsIRDFContainer MakeSeq ( nsIRDFDataSource dataSource , nsIRDFResource resource ) PRInt32 OrdinalResourceToIndex ( nsIRDFResource ordinal )

PRInt32 indexOf ( nsIRDFDataSource dataSource , nsIRDFResource container , nsIRDFNode element )

Retrieve the index of element in the container. Returns -1 if the element is not in the container.

Arguments:
dataSource
container
element

nsIRDFResource IndexToOrdinalResource ( PRInt32 index )

Convert the specified index to an ordinal property.

Arguments:
index

PRBool IsAlt ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Return 'true' if the specified resource is an alternation

Arguments:
dataSource
resource

PRBool IsBag ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Return 'true' if the specified resource is a bag

Arguments:
dataSource
resource

PRBool IsContainer ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Return 'true' if the specified resource is a container

Arguments:
dataSource
resource

PRBool IsEmpty ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Return 'true' if the specified resource is a container and it is empty

Arguments:
dataSource
resource

PRBool IsOrdinalProperty ( nsIRDFResource property )

Returns 'true' if the property is an RDF ordinal property.

Arguments:
property

PRBool IsSeq ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Return 'true' if the specified resource is a sequence

Arguments:
dataSource
resource

nsIRDFContainer MakeAlt ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Decorates the specified resource appropriately to make it usable as an empty alternation in the specified data source.

Arguments:
dataSource
resource

nsIRDFContainer MakeBag ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Decorates the specified resource appropriately to make it usable as an empty bag in the specified data source.

Arguments:
dataSource
resource

nsIRDFContainer MakeSeq ( nsIRDFDataSource dataSource , nsIRDFResource resource )

Decorates the specified resource appropriately to make it usable as an empty sequence in the specified data source.

Arguments:
dataSource
resource

PRInt32 OrdinalResourceToIndex ( nsIRDFResource ordinal )

Convert the specified ordinal property into an index

Arguments:
ordinal
