read

back to summary

public abstract Object read(JSONReader reader, JsonParser p) throws IOException

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.

Parameters

reader: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

readNext back to summary

readNext	back to summary
public Object readNext(JSONReader reader, JsonParser p) throws IOException 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 reader: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

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

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.

Parameters

p:JsonParser: Underlying parser used for reading decoded token stream
