      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
