All Implemented Interfaces:

public class Json5lTokenReader
extends Json5TokenReader

Reference implementation of the public TokenReader surface for the JSON5L format.

Subclasses Json5TokenReader to inherit the JSON5 dialect relaxations (single-quoted and bare-identifier strings/field names, trailing commas, missing values, comments) and adds JSONL's flat top-level sequencing: each line's value is emitted in turn at depth 0 and JsonTokenReader.next() returns TokenType.END_OF_STREAM only when the input is exhausted.

Notes:

• This class is not thread safe.
• The cursor is a true O(1)-memory streaming cursor (TokenReader.isStreaming() == true).

Constructor Details

Json5lTokenReader

public Json5lTokenReader(ParserPipe pipe)
                  throws IOException

Constructor with default settings.

Parameters:

pipe - The parser input pipe to read from. Must not be null.

Throws:

IOException - If a problem occurred opening the underlying reader.

Json5lTokenReader

public Json5lTokenReader(ParserPipe pipe,
 JsonTokenReader.Settings settings,
 Json5lParserSession session)
                  throws IOException

Constructor used by Json5lParserSession.readTokens(Object) to plumb the calling session through so that JsonTokenReader.read(Class) can delegate to the JSON5L databind path.

Parameters:

pipe - The parser input pipe. Must not be null.

settings - The cursor-level settings. Must not be null.

session - The Json5lParserSession for JsonTokenReader.read(Class) delegation, or null to disable read.

Throws:

IOException - If a problem occurred opening the underlying reader.

Method Details

afterValue

protected void afterValue()

Description copied from class: JsonTokenReader

Sets the post-value state based on the enclosing container.

Subclasses (e.g. JsonlTokenReader) override this when the format treats consecutive top-level values differently — JSONL transitions back to JsonTokenReader.S00_expectValue at depth 0 instead of JsonTokenReader.S05_end so the next line is read.

Overrides:
