Class PlaceholderEnabledJsonNodeFactory

java.lang.Object

com.fasterxml.jackson.databind.node.JsonNodeFactory

org.jmxtrans.embedded.util.json.PlaceholderEnabledJsonNodeFactory

All Implemented Interfaces:

Serializable

public class PlaceholderEnabledJsonNodeFactory
extends com.fasterxml.jackson.databind.node.JsonNodeFactory

Property placeholder / substitution enabled JsonNodeFactory.

Each JSON text value is processed by the PropertyPlaceholderResolver before building a TextNode.

Inspired by Spring Framework PropertyPlaceHolder and by Jakarta Digester Substitution.

Constructor Detail

PlaceholderEnabledJsonNodeFactory

public PlaceholderEnabledJsonNodeFactory(boolean bigDecimalExact)

Main constructor

The only argument to this constructor is a boolean telling whether DecimalNode instances must be built with exact representations of BigDecimal instances.

This has quite an influence since, for instance, a BigDecimal (and, therefore, a DecimalNode) constructed from input string "1.0" and another constructed with input string "1.00" will not be equal, since their scale differs (1 in the first case, 2 in the second case).

Note that setting the argument to true does not guarantee a strict inequality between JSON representations: input texts "0.1" and "1e-1", for instance, yield two equivalent BigDecimal instances since they have the same scale (1).

The no-arg constructor (and the default JsonNodeFactory.instance) calls this constructor with false as an argument.

Parameters:

bigDecimalExact - see description
