Method Detail

readNext

public Object readNext(JSONReader r,
                       JsonParser p)
                throws IOException

Description copied from class: ValueReader

Method called to deserialize value of type supported by this reader, using given parser. Parser is not yet positioned to the (first) token of the value to read and needs to be advanced.

Default implementation simply calls `p.nextToken()` first, then calls {#link ValueReader.read(JSONReader, JsonParser), but some implementations may decide to implement this differently to use (slightly) more efficient accessor in JsonParser, like JsonParser.nextIntValue(int).

Overrides:

readNext in class ValueReader

Parameters:

r - Context object that allows calling other read methods for contained values of different types (for example for collection readers).

p - Underlying parser used for reading decoded token stream

Throws:

IOException

read

public Object read(JSONReader r,
                   JsonParser p)
            throws IOException

Description copied from class: ValueReader

Method called to deserialize value of type supported by this reader, using given parser. Parser is already positioned to the (first) token of the value to read.

Specified by:

read in class ValueReader

Parameters:

r - Context object that allows calling other read methods for contained values of different types (for example for collection readers).

p - Underlying parser used for reading decoded token stream

Throws:

IOException

_reportProblem

protected JSONObjectException _reportProblem(JsonParser p)
