final class PrettyJsonBuilder extends Builder[StringOrInt, JsonValue, Failures, String]

A builder whose output is a json-formatted string.

I imagine giving this thing enough key-value pairs will result in an OutOfMemoryError when it tries to create the string, but I have yet to go about trying to detect and fast-fail in that situation, or creating a structure that is indistinguishable from a really long Seq[Char]

    params

    the amount whitespace to insert between tokens

    charset

    The output will only contain characters that can be encoded using the specified charset. Any characters outside the charset will be u-escaped. Default is to keep all characters that are allowed by Json. There may be problems if the charset does not include at least ASCII characters.

    level

    the indentation level of this builder instance

    A function to be called after the folding to produce a result

    A function to be called after the folding to produce a result

    Taking advantage of this method might be useful if either Middle is mutable for performance reasons and Result should be immutable or if the builder needs to use multiple key-value pairs fromt the source to produce some value in the domain object.

    If there is no need to take advantage of this, the implementation of this method can be

    override def finish[BFE](bfe:BFE)(x:Middle) = ParserRetVal.Complex(x)
    folding

    the object to be converted. Must be either the return value of init or the return value of apply

    returns

    either a built value or an error value

    Most useful if the Parser input is neither stable nor resendable - say a network stream.
