java.lang.Object

dev.toonformat.jtoon.encoder.TabularArrayEncoder

public final class TabularArrayEncoder
extends Object

Detects and encodes uniform arrays of objects in efficient tabular format. Tabular format declares field names once in a header and streams rows as CSV-like data.

detectTabularHeader

public static List<String> detectTabularHeader(tools.jackson.databind.node.ArrayNode rows)

Detects if an array can be encoded in tabular format. Returns the header fields if tabular encoding is possible, empty list otherwise.

Parameters:

rows - The array to analyze

Returns:

List of field names for tabular header, or empty list if not tabular

encodeArrayOfObjectsAsTabular

public static void encodeArrayOfObjectsAsTabular(String prefix,
 tools.jackson.databind.node.ArrayNode rows,
 List<String> header,
 LineWriter writer,
 int depth,
 EncodeOptions options)

Encodes an array of objects as a tabular structure.

Parameters:

prefix - Optional key prefix

rows - Array of uniform objects

header - List of field names

writer - LineWriter for output

depth - Indentation depth

options - Encoding options

writeTabularRows

public static void writeTabularRows(tools.jackson.databind.node.ArrayNode rows,
 List<String> header,
 LineWriter writer,
 int depth,
 EncodeOptions options)

Writes rows of tabular data by extracting values in header order. Public to allow ListItemEncoder to write rows after placing header on "- " line.

Parameters:

rows - Array of objects

header - List of field names

writer - LineWriter for output

depth - Indentation depth

options - Encoding options
