Deserializes a non-null JSON input into an object.

Specified by:

doDeserialize in class JsonDeserializer<T>

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

Returns:

the deserialized object

Throws:

IOException - if an error occurs reading the input

doDeserializeArray

protected abstract T doDeserializeArray(JsonReader reader,
                   JsonDeserializationContext ctx)
                                 throws IOException

Throws:

IOException

doDeserializeNonArray

protected T doDeserializeNonArray(JsonReader reader,
                      JsonDeserializationContext ctx)
                           throws IOException

Throws:

IOException

doDeserializeSingleArray

protected abstract T doDeserializeSingleArray(JsonReader reader,
                         JsonDeserializationContext ctx)
                                       throws IOException

Throws:

IOException

deserializeIntoList

protected <C> List<C> deserializeIntoList(JsonReader reader,
                              JsonDeserializationContext ctx,
                              JsonDeserializer<C> deserializer)
                               throws IOException

Deserializes the array into a List. We need the length of the array before creating it.

Type Parameters:

C - type of the element inside the array

Parameters:

reader - reader

ctx - context of the deserialization process

deserializer - deserializer for element inside the array

Returns:

a list containing all the elements of the array

Throws:

IOException - if an error occurs while reading the array
