public ReferenceNode()

ReferenceNode

public ReferenceNode(String value)

Creates a new ReferenceNode with the given value.

value - the value of this ReferenceNode

Method Detail

value

public String value()

Returns the value of this reference node. Same as toString() since the value of a ReferenceNode is a String (but implementations in other LeafNode sub-classes differ).

Overrides:

value in class LeafNode<String>

Returns:

the string representation of this ReferenceNode.

getValue

public String getValue()

Description copied from class: LeafNode

Subclasses must implement this, in compliance with the rules given in the return tag.

Specified by:

getValue in class LeafNode<String>

Returns:

the String representation of the node value, or the 'null' object if the node value is null.

toString

public String toString()

Description copied from class: LeafNode

Subclasses must implement this, in compliance with the rules given in the return tag.

Specified by:

toString in class LeafNode<String>

Returns:

the String representation of the node value, or the string "(null)" if the value is null.

doSetValue

protected boolean doSetValue(String value)

Specified by:

doSetValue in class LeafNode<String>

postInitialize

public void postInitialize(String configId)

Overrides Node.postInitialize(String) Checks for ":parent:" values, which will be replaced by the configId.

Overrides:

postInitialize in class Node

Parameters:

configId - the configId of the ConfigInstance that owns (or is) this node
