given that this class is stateless, a globally shared singleton
can be used.

using data binding, usually as JSON Objects, but in some
cases as JSON Strings or other node types.
|

public static final JsonNodeFactory instance
public JsonNodeFactory(boolean bigDecimalExact)
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 instance
) calls this
constructor with false
as an argument.
bigDecimalExact
- see descriptionBigDecimal
protected JsonNodeFactory()
This calls JsonNodeFactory(boolean)
with false
as an argument.

values, the BigDecimal argument will be stripped off its trailing zeroes,
using BigDecimal.stripTrailingZeros()
