IOLink.MetadataNode Class Reference

Class which represents one node from a metadata tree. Each node contains a key and also an associated value (optional). It also contains a list of nodes which represents its children in the tree. Children can be parsed using '(Const)MetadataNodeIterator' objects provided by '(c)begin' and '(c)end' methods, or directly can be retrieved thanks to 'child' accessor method. More...

Detailed Description

Class which represents one node from a metadata tree. Each node contains a key and also an associated value (optional). It also contains a list of nodes which represents its children in the tree. Children can be parsed using '(Const)MetadataNodeIterator' objects provided by '(c)begin' and '(c)end' methods, or directly can be retrieved thanks to 'child' accessor method.

Examples

CopyImageView.cs, and MetadataTree.cs.

MetadataNode()

IOLink.MetadataNode.MetadataNode ( string  key, VariantDataValue  value  )

inline

Constructor which takes a mandatory key, and an optional value.

Parameters

key	string which identifies the node
value	VariantDataValue object associated to the key (or null)

Member Function Documentation

AddChild()

void IOLink.MetadataNode.AddChild ( MetadataNode  child )

inline

Add a node as child. If the given child key already exists in the current node, existing child is replaced by new one.

Parameters

child

node to add as child to the current node

Examples

MetadataTree.cs.

Child()

ReadonlyMetadataNode IOLink.MetadataNode.Child ( string  key )

inline

Return the child node with the given key.

Parameters

key	the key corresponding to one of the children of current node

Returns

the child corresponding to given key

Exceptions

Error

If the key is not found in the children of the current node

Clone()

MetadataNode IOLink.MetadataNode.Clone ( )

inline

Method to clone the current node.

Returns

the new node

GetKey()

string IOLink.MetadataNode.GetKey ( )

inline

Accessor to the key of the current node.

Returns

the current node key

GetValue()

VariantDataValue IOLink.MetadataNode.GetValue ( )

inline

Accessor to the value of the current node.

Returns

the current node value

HasChild()

bool IOLink.MetadataNode.HasChild ( string  key )

inline

Indicate if a child identified by its key is present or not.

Parameters

key	the key corresponding to a child or not of current node

Returns

If the node has a child with given key

RemoveChild()

void IOLink.MetadataNode.RemoveChild ( string  key )

inline

Remove child identified by its key.

Parameters

key	Key whose node must be removed
