Class JsonReader

  • public final class JsonReader
extends java.lang.Object
    A simple JSON parser mapping tokens to basic Java types.

    The type mapping is as follows:

    • objects are mapped to LinkedHashMap<String,Object>
    • arrays are mapped to LinkedList
    • strings are mapped to String with proper Unicode and escape character conversion
    • true, false, and null are mapped to their Java counterparts
    • floating point numbers are mapped to BigDecimal
    • integral numbers are mapped to either primitive types (int, long) or BigInteger

    This code is heavily influenced by the reader of mjson.
