Constructor Detail

• ByteSourceJsonBootstrapper

  public ByteSourceJsonBootstrapper(IOContext ctxt,
                                    InputStream in)

• ByteSourceJsonBootstrapper

  public ByteSourceJsonBootstrapper(IOContext ctxt,
                                    byte[] inputBuffer,
                                    int inputStart,

Method Detail

• detectEncoding

  public JsonEncoding detectEncoding()
                              throws IOException

  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.

  Returns:

  JsonEncoding detected, if any; JsonEncoding.UTF8 otherwise

  Throws:

  IOException - If read from underlying input source fails

• skipUTF8BOM

  public static int skipUTF8BOM(DataInput input)
                         throws IOException

  Helper method that may be called to see if given DataInput has BOM marker, and if so, to skip it.

  Parameters:

  input - DataInput to read content from

  Returns:

  Byte (as unsigned int) read after possible UTF-8 BOM

  Throws:

  IOException - If read from underlying input source fails

  Since:

  2.8

• constructReader

  public Reader constructReader()
                         throws IOException

  Throws:

  IOException

• constructParser

  public JsonParser constructParser(int parserFeatures,
                                    ObjectCodec codec,
                                    ByteQuadsCanonicalizer rootByteSymbols,
                                    CharsToNameCanonicalizer rootCharSymbols,
                                    int factoryFeatures)
                             throws IOException

  Throws:

  IOException

• 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.

  Parameters:

  acc - InputAccessor to use for accessing content to check

  Returns:

  Strength of match (never null)

  Throws:

  IOException - if input access fails due to read problem

• ensureLoaded

  protected boolean ensureLoaded(int minimum)
                          throws IOException

  Throws:

  IOException
