final class PiecewiseBuilder[Key, Value, Subject] extends Builder[Key, Value, Subject]

A Builder which can be built piecewise.

Key

the key types

Value

the primitive value types

Subject

the type of object to build

Source
PiecewiseBuilder.scala
Example:
  1. case class Foo(a:String, b:Seq[JsonValue], c:String)
    val fooBuilder = (new PiecewiseBuilder[StringOrInt, JsonValue, Foo](new Foo("", Seq.empty, ""))
    	.addDef(StringOrInt("a"), partitionedPrimitiveKeyDef({case JsonValueString(x) => Right(x)}, {(f:Foo, x:String) => f.copy(a = x)}))
    	.addDef(StringOrInt("c"), partitionedPrimitiveKeyDef({case JsonValueString(x) => Right(x)}, {(f:Foo, x:String) => f.copy(c = x)}))
    	.addDef(StringOrInt("b"), partitionedComplexKeyDef(new PrimitiveSeqBuilder[JsonValue], {(f:Foo, x:Seq[JsonValue]) => Right(f.copy(b = x))}))
    )
    val jsonParser = new JsonParser
    jsonParser.parse(fooBuilder, """{"a":"","b":[]}""")
    // results in `Foo("", Seq.empty, "")`
    jsonParser.parse(fooBuilder, """{"a":"qwer","b":["z","x","c"],"c":"asdf"}""")
    // results in `Foo("qwer", Seq(JsonValueString("z"), JsonValueString("x"),JsonValueString("c")), "asdf")`

    Add a key-value pair to folding

    Add a key-value pair to folding

    The key is key, and the value is the result of com.rayrobdod.json.parser.Parser.parse on the provided input.

    folding

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

    key

    the key of a key-value pair

    input

    the input to a parser

    parser

    a parser for turning input into a value

    returns

    • A scala.util.Right containing the built value, or
    • A scala.util.Left indicating an error message and error index
