Method Details

wrap

public static ObjectNodeImpl wrap(ConfigNode.ObjectNode objectNode)

Wraps value node into mergeable value node.

Parameters:

objectNode - original node

Returns:

new instance of mergeable node or original node if already was mergeable.

wrap

public static ObjectNodeImpl wrap(ConfigNode.ObjectNode objectNode,
 Function<String,String> resolveTokenFunction)

Wraps value node into mergeable value node.

Parameters:

objectNode - original node

resolveTokenFunction - a token resolver

Returns:

new instance of mergeable node or original node if already was mergeable.

entrySet

public Set<Map.Entry<String, ConfigNode>> entrySet()

Specified by:

entrySet in interface Map<String, ConfigNode>

Specified by:

entrySet in class AbstractMap<String, ConfigNode>

merge

public MergeableNode merge(MergeableNode node)

Description copied from interface: MergeableNode

Returns new instance mergeable node of same type of original one that merges also with specified node.

Specified by:

merge in interface MergeableNode

Parameters:

node - node to be used to merge with

Returns:

new instance of mergeable node that combines original node with specified one

toString

public String toString()

Overrides:

toString in class AbstractMap<String, ConfigNode>

initDescription

public ObjectNodeImpl initDescription(String description)

Initialize diagnostics description of source of node instance.

Parameters:

description - diagnostics description

Returns:

this instance

description

public String description()

Description of this node.

Returns:

node description

hasValue

public boolean hasValue()

Description copied from interface: MergeableNode

Each node may have a direct value, and in addition may be an object node or a list node. This method returns true for any node with direct value.

Specified by:

hasValue in interface MergeableNode

Returns:

true if this node contains a value

value

public Optional<String> value()

Description copied from interface: ConfigNode

Get the direct value of this config node. Any node type can have a direct value.

Specified by:

value in interface ConfigNode

Returns:

a value if present, empty otherwise
