Implements abstract com.fasterxml.jackson.jr.ob.api.ValueReader.read.

Method used for deserialization; will read an instance of the bean type using given parser.

Parameters
r:JSONReader

Doc from com.fasterxml.jackson.jr.ob.api.ValueReader.read.

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

p:JsonParser

Doc from com.fasterxml.jackson.jr.ob.api.ValueReader.read.

Underlying parser used for reading decoded token stream

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

Overrides com.fasterxml.jackson.jr.ob.api.ValueReader.readNext.

Doc from com.fasterxml.jackson.jr.ob.api.ValueReader.readNext.

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 read(JSONReader, JsonParser), but some implementations may decide to implement this differently to use (slightly) more efficient accessor in JsonParser, like JsonParser#nextIntValue(int).

Parameters
r:JSONReader

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

p:JsonParser

Underlying parser used for reading decoded token stream
