org.hotwheel.json.impl.jackson.JsonParserDelegate

org.hotwheel.json.impl.jackson.JsonParserSequence

所有已实现的接口:

Closeable, AutoCloseable, Versioned

public class JsonParserSequence
extends JsonParserDelegate

Helper class that can be used to sequence multiple physical JacksonParsers to create a single logical sequence of tokens, as a single JacksonParser.

Fairly simple use of JsonParserDelegate: only need to override nextToken() to handle transition

方法概要

限定符和类型	方法和说明
void	close() Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JacksonParser.Feature.AUTO_CLOSE_SOURCE is enabled.
int	containedParsersCount() Method that is most useful for debugging or testing; returns actual number of underlying parsers sequence was constructed with (nor just ones remaining active)
static JsonParserSequence	createFlattened(JacksonParser first, JacksonParser second) Method that will construct a parser (possibly a sequence) that contains all given sub-parsers.
JsonToken	nextToken() Main iteration method, which will advance stream enough to determine type of the next token, if any.

createFlattened

public static JsonParserSequence createFlattened(JacksonParser first,
                                                 JacksonParser second)

Method that will construct a parser (possibly a sequence) that contains all given sub-parsers. All parsers given are checked to see if they are sequences: and if so, they will be "flattened", that is, contained parsers are directly added in a new sequence instead of adding sequences within sequences. This is done to minimize delegation depth, ideally only having just a single level of delegation.

close

public void close()
           throws IOException

从类复制的说明: JacksonParser

Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JacksonParser.Feature.AUTO_CLOSE_SOURCE is enabled. Whether parser owns the input source depends on factory method that was used to construct instance (so check JsonFactory for details, but the general idea is that if caller passes in closable resource (such as InputStream or Reader) parser does NOT own the source; but if it passes a reference (such as File or URL and creates stream or reader it does own them.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 JsonParserDelegate

抛出:

IOException

nextToken

public JsonToken nextToken()
                    throws IOException,
                           JsonParseException

从类复制的说明: JacksonParser

Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.

覆盖:

nextToken 在类中 JsonParserDelegate

返回:

Next token from the stream, if any found, or null to indicate end-of-input

抛出:

IOException

JsonParseException

containedParsersCount

public int containedParsersCount()

Method that is most useful for debugging or testing; returns actual number of underlying parsers sequence was constructed with (nor just ones remaining active)
