类 ByteSourceJsonBootstrapper

java.lang.Object

org.hotwheel.json.impl.jackson.ByteSourceJsonBootstrapper

public final class ByteSourceJsonBootstrapper
extends Object

This class is used to determine the encoding of byte stream that is to contain JSON content. Rules are fairly simple, and defined in JSON specification (RFC-4627 or newer), except for BOM handling, which is a property of underlying streams.

hasJSONFormat

public static MatchStrength hasJSONFormat(InputAccessor acc)
                                   throws IOException

Current implementation is not as thorough as other functionality (ByteSourceJsonBootstrapper); supports UTF-8, for example. But it should work, for now, and can be improved as necessary.

抛出:

IOException

detectEncoding

public JsonEncoding detectEncoding()
                            throws IOException,
                                   JsonParseException

Method that should be called after constructing an instace. It will figure out encoding that content uses, to allow for instantiating a proper scanner object.

抛出:

IOException

JsonParseException

constructReader

public Reader constructReader()
                       throws IOException

抛出:

IOException

constructParser

public JacksonParser constructParser(int parserFeatures,
                                     ObjectCodec codec,
                                     BytesToNameCanonicalizer rootByteSymbols,
                                     CharsToNameCanonicalizer rootCharSymbols,
                                     boolean canonicalize,
                                     boolean intern)
                              throws IOException,
                                     JsonParseException

抛出:

IOException
