Constructor Details

ConfigBasicInternalMNode

public ConfigBasicInternalMNode(IConfigMNode parent,
 String name)

Constructor of MNode.

Method Details

hasChild

public boolean hasChild(String name)

check whether the MNode has a child with the name

Specified by:

hasChild in interface IMNode<IConfigMNode>

Overrides:

hasChild in class ConfigBasicMNode

getChild

public IConfigMNode getChild(String name)

get the child with the name

Specified by:

getChild in interface IMNode<IConfigMNode>

Overrides:

getChild in class ConfigBasicMNode

addChild

public IConfigMNode addChild(String name,
 IConfigMNode child)

add a child to current mnode

Specified by:

addChild in interface IMNode<IConfigMNode>

Overrides:

addChild in class ConfigBasicMNode

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>

Overrides:

addChild in class ConfigBasicMNode

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>

Overrides:

deleteChild in class ConfigBasicMNode

getChildren

public IMNodeContainer<IConfigMNode> getChildren()

Specified by:

getChildren in interface IMNode<IConfigMNode>

Overrides:

getChildren in class ConfigBasicMNode

setChildren

public void setChildren(IMNodeContainer<IConfigMNode> children)

Specified by:

setChildren in interface IMNode<IConfigMNode>

Overrides:

setChildren in class ConfigBasicMNode

estimateSize

public int estimateSize()

MNodeContainer reference and basic occupation, 8 + 80B

Specified by:

estimateSize in interface IMNode<IConfigMNode>

Overrides:

estimateSize in class ConfigBasicMNode

getMNodeType

public MNodeType getMNodeType()

getAsMNode

public IConfigMNode getAsMNode()
