public class UTF8DataInputWithDocLengthJsonParser
extends UTF8DataInputJsonParser

Specialization of UTF8DataInputJsonParser that tracks the number of bytes read and enforces the StreamReadConstraints.getMaxDocumentLength() limit.

Byte tracking is achieved by overriding readUnsignedByte(): every call increments _bytesRead so that validation can be performed at token boundaries in nextToken().

3.2

public UTF8DataInputWithDocLengthJsonParser(ObjectReadContext readCtxt,
 IOContext ctxt,
 int stdFeatures,

 int firstByte)

Method Details

readUnsignedByte

protected int readUnsignedByte()
                        throws IOException

Description copied from class: UTF8DataInputJsonParser

Read the next unsigned byte from the input. Subclasses may override to track byte counts for document length enforcement.

Overrides:

readUnsignedByte in class UTF8DataInputJsonParser

Throws:

IOException

nextToken

public JsonToken nextToken()
                    throws JacksonException

Description copied from class: JsonParser

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.

Overrides:

nextToken in class UTF8DataInputJsonParser

Returns:

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

Throws:

JacksonException - for low-level read issues
