Syntax

[CLSCompliant(false)]
public class ContentNodeIterator

Constructors

ContentNodeIterator(IAbstractContainerNode)

Limit iteration to the specified container, start at the first node in the container.

Declaration

public ContentNodeIterator(IAbstractContainerNode container)

Parameters

Type	Name	Description
IAbstractContainerNode	container	The bounding container

ContentNodeIterator(IAbstractContainerNode, IAbstractNode)

Limit iteration to the specified container, start at a specified node (which should be in the container, but can be a sub-node).

Declaration

public ContentNodeIterator(IAbstractContainerNode container, IAbstractNode from)

Parameters

Type	Name	Description
IAbstractContainerNode	container	The bounding container
IAbstractNode	from	The first node to start from. This is typically a node somewhere inside the container.

ContentNodeIterator(IAbstractNode)

Start at the specified node. Iterate until the end of all available content, including parent nodes.

Declaration

public ContentNodeIterator(IAbstractNode from)

Parameters

Type	Name	Description
IAbstractNode	from	the position to start from, may or may not be a content node

ContentNodeIterator(IAbstractNode, IAbstractContentNode)

Limit iteration to a specific end node. The iteration will stop at the upto node, which will not be returned as a content node.

Declaration

public ContentNodeIterator(IAbstractNode from, IAbstractContentNode upto)

Parameters

Type	Name	Description
IAbstractNode	from	The first node to start from. May or may not be a container.
IAbstractContentNode	upto	The node at which to stop. Will not be part of the content iterated over, and must be after the from node to be effective.

Fields

_Container

Container the search is limited to

Declaration

protected IAbstractContainerNode _Container

Field Value

Type	Description
IAbstractContainerNode

_CurrentNode

The node currently selected

Declaration

protected IAbstractNode _CurrentNode

Field Value

Type	Description
IAbstractNode

_EndNode

The node that will end iteration

Declaration

protected IAbstractContentNode _EndNode

Field Value

Type	Description
IAbstractContentNode

Properties

Container

The container that iteration is limited to, or null if none.

Declaration

public IAbstractContainerNode Container { get; set; }

Property Value

Type	Description
IAbstractContainerNode

CurrentAbstractNode

The current node. This base implementation simply returns CurrentNode but derived implementations may need to return a more generic type.

Declaration

protected virtual IAbstractNode CurrentAbstractNode { get; }

Property Value

Type	Description
IAbstractNode

CurrentNode

The current content node, or null if none.

Declaration

public IAbstractContentNode CurrentNode { get; set; }

Property Value

Type	Description
IAbstractContentNode

EndNode

The iteration stops when this node is reached. It is not returned as a current node.

Declaration

public IAbstractContentNode EndNode { get; set; }

Property Value

Type	Description
IAbstractContentNode

Methods

GetNextContentNode(IAbstractNode)

Convenience method that allows easy access to the next content node.

This is exactly the same as creating a ContentNodeIterator, calling Next on it and taking the CurrentNode.

Declaration

public static IAbstractContentNode GetNextContentNode(IAbstractNode from)

Parameters

Type	Name	Description
IAbstractNode	from	The content node to start iterating from.

Returns

Type	Description
IAbstractContentNode	The next content node in the document, null if no node was found.

Next()

Advance to the next content node.

Declaration

public bool Next()

Returns

Type	Description
System.Boolean	true if another content node was found, false if not, or the end of the bounding container was reached.

Previous()

Backs the iterator to the previous node.

Declaration

public bool Previous()

Returns

Type	Description
System.Boolean	true if the operation is successful, i.e. if there is a preceding content node

Remarks

Note that when backing the iterator does not check for stop conditions.
