Class JPropNode

java.lang.Object

com.fasterxml.jackson.dataformat.javaprop.util.JPropNode

public class JPropNode
extends Object

Value in an ordered tree presentation built from an arbitrarily ordered set of flat input values. Since either index- OR name-based access is to be supported (similar to, say, Javascript objects) -- but only one, not both -- storage is bit of a hybrid. In addition, branches may also have values. So, code does bit coercion as necessary, trying to maintain something consistent and usable at all times, without failure.

Field Detail

_value

protected String _value

Value for the path, for leaf nodes; usually null for branches. If both children and value exists, typically need to construct bogus value with empty String key.

_byIndex

protected TreeMap<Integer,JPropNode> _byIndex

Child entries with integral number index, if any.

_byName

protected Map<String,JPropNode> _byName

Child entries accessed with String property name, if any.

_hasContents

protected boolean _hasContents
