Constructor Details

ConfigBasicMNode

public ConfigBasicMNode(IConfigMNode parent,
 String name)

Constructor of MNode.

Method Details

getName

public String getName()

Specified by:

getName in interface IMNode<IConfigMNode>

Specified by:

getName in interface ITreeNode

setName

public void setName(String name)

Specified by:

setName in interface IMNode<IConfigMNode>

getParent

public IConfigMNode getParent()

Specified by:

getParent in interface IMNode<IConfigMNode>

setParent

public void setParent(IConfigMNode parent)

Specified by:

setParent in interface IMNode<IConfigMNode>

getFullPath

public String getFullPath()

Specified by:

getFullPath in interface IMNode<IConfigMNode>

setFullPath

public void setFullPath(String fullPath)

Specified by:

setFullPath in interface IMNode<IConfigMNode>

getPartialPath

public PartialPath getPartialPath()

Specified by:

getPartialPath in interface IMNode<IConfigMNode>

hasChild

public boolean hasChild(String name)

check whether the MNode has a child with the name

Specified by:

hasChild in interface IMNode<IConfigMNode>

getChild

public IConfigMNode getChild(String name)

get the child with the name

Specified by:

getChild in interface IMNode<IConfigMNode>

addChild

public IConfigMNode addChild(String name,
 IConfigMNode child)

add a child to current mnode

Specified by:

addChild in interface IMNode<IConfigMNode>

Parameters:

name - child's name

child - child's node

Returns:

the child of this node after addChild

addChild

public IConfigMNode addChild(IConfigMNode child)

Add a child to the current mnode.

This method will not take the child's name as one of the inputs and will also make this Mnode be child node's parent. All is to reduce the probability of mistaken by users and be more convenient for users to use. And the return of this method is used to conveniently construct a chain of time series for users.

Specified by:

addChild in interface IMNode<IConfigMNode>

Parameters:

child - child's node

Returns:

return the MNode already added

deleteChild

public IConfigMNode deleteChild(String name)

delete a child

Specified by:

deleteChild in interface IMNode<IConfigMNode>

getChildren

public IMNodeContainer<IConfigMNode> getChildren()

Specified by:

getChildren in interface IMNode<IConfigMNode>

setChildren

Specified by:

setChildren in interface IMNode<IConfigMNode>

isAboveDatabase

Specified by:

isAboveDatabase in interface IMNode<IConfigMNode>

isDatabase

public boolean isDatabase()

Specified by:

isDatabase in interface IMNode<IConfigMNode>

getAsDatabaseMNode

public IDatabaseMNode<IConfigMNode> getAsDatabaseMNode()

Specified by:
