Method Details

• encodeWithTypeInfo

  public static elemental.json.JsonValue encodeWithTypeInfo(Object value)

  Helper for encoding values that might not have a native representation in JSON. Such types are encoded as an JSON array starting with an id defining the actual type and followed by the actual data. Supported value types are any native JSON type supported by encodeWithoutTypeInfo(Object), Element and Component (encoded as its root element).

  Parameters:

  value - the value to encode

  Returns:

  the value encoded as JSON

• canEncodeWithoutTypeInfo

  public static boolean canEncodeWithoutTypeInfo(Class<?> type)

  Helper for checking whether the type is supported by encodeWithoutTypeInfo(Object). Supported value types are String, Integer, Double, Boolean, JsonValue.

  Parameters:

  type - the type to check

  Returns:

  whether the type can be encoded

• canEncodeWithTypeInfo

  public static boolean canEncodeWithTypeInfo(Class<?> type)

  Helper for checking whether the type is supported by encodeWithTypeInfo(Object). Supported values types are Node, Component, ReturnChannelRegistration and anything accepted by canEncodeWithoutTypeInfo(Class).

  Parameters:

  type - the type to check

  Returns:

  whether the type can be encoded

• encodeWithConstantPool

  public static elemental.json.JsonValue encodeWithConstantPool(Object value, ConstantPool constantPool)

  Encodes a "primitive" value or a constant pool reference to JSON. This methods supports ConstantPoolKey in addition to the types supported by encodeWithoutTypeInfo(Object).

  Parameters:

  value - the value to encode

  constantPool - the constant pool to use for encoding constant pool references

  Returns:

  the value encoded as JSON

• encodeWithoutTypeInfo

  public static elemental.json.JsonValue encodeWithoutTypeInfo(Object value)

  Helper for encoding any "primitive" value that is directly supported in JSON. Supported values types are String, Number, Boolean, JsonValue. null is also supported.

  Parameters:

  value - the value to encode

  Returns:

  the value encoded as JSON

  Parameters:

  json - the JSON value to decode

  Returns:

  the decoded value

• decodeAs

  Supported types are String, Boolean, Integer, Double and primitives boolean, int, double

  Type Parameters:

  T - the decoded type
