dev.tachyonmcp.core.transport.jsonrpc.JsonRpcCodec

public final class JsonRpcCodec
extends Object

Low-level JSON-RPC 2.0 codec: parse and serialize messages to/from Netty ByteBuf.

Method Summary

Modifier and Type	Method	Description
static JsonRpcMessage	parseRequest(io.netty.buffer.ByteBuf buf)	Parses a JSON-RPC message from a ByteBuf.
static @Nullable Object	readGenericValue(tools.jackson.core.JsonParser p)	Reads the current JSON token as a generic Java value.
static String	readRawJson(tools.jackson.core.JsonParser p)	Reads the remainder of the current JSON value as a raw JSON string.
static tools.jackson.databind.JsonNode	readTreeValue(tools.jackson.core.JsonParser p)	Reads the current JSON value as a JsonNode.
static @Nullable Object	readValue(String json)	Deserializes a JSON string to a generic Java object (Map, List, String, Number, Boolean, or null).
static byte[]	serializeError(@Nullable RequestId id, int code, String message, @Nullable String dataJson)	Serializes a JSON-RPC error response.
static String	serializeNotificationAsString(String method, String paramsJson)	Serializes a JSON-RPC notification to a string.
static String	serializeRequestAsString(RequestId id, String method, String paramsJson)	Serializes a JSON-RPC request to a string.
static byte[]	serializeResponse(@Nullable RequestId id, @Nullable String resultJson)	Serializes a JSON-RPC response.
static String	toJsonParams(@Nullable Object params)	Serializes JSON-RPC params to a JSON string: strings pass through as already-serialized JSON, null becomes an empty object, everything else goes through writeValueAsString(java.lang.Object).
static void	writeJsonValue(tools.jackson.core.JsonGenerator gen, @Nullable Object value)	Writes a Java object as a JSON value via the given generator.
static @Nullable String	writeValueAsString(@Nullable Object value)	Serializes a Java object to a JSON string, using registered codecs when available.

Method Details

parseRequest

public static JsonRpcMessage parseRequest(io.netty.buffer.ByteBuf buf)

Parses a JSON-RPC message from a ByteBuf.

serializeResponse

public static byte[] serializeResponse(@Nullable RequestId id,
 @Nullable String resultJson)

Serializes a JSON-RPC response.

serializeError

public static byte[] serializeError(@Nullable RequestId id,
 int code,
 String message,
 @Nullable String dataJson)

Serializes a JSON-RPC error response.

serializeNotificationAsString

public static String serializeNotificationAsString(String method,
 String paramsJson)

Serializes a JSON-RPC notification to a string.

serializeRequestAsString

public static String serializeRequestAsString(RequestId id,
 String method,
 String paramsJson)

Serializes a JSON-RPC request to a string.

readRawJson

public static String readRawJson(tools.jackson.core.JsonParser p)

Reads the remainder of the current JSON value as a raw JSON string.

readTreeValue

public static tools.jackson.databind.JsonNode readTreeValue(tools.jackson.core.JsonParser p)
                                                     throws IOException

Reads the current JSON value as a JsonNode.

Throws:

IOException

readValue

public static @Nullable Object readValue(String json)

Deserializes a JSON string to a generic Java object (Map, List, String, Number, Boolean, or null).

readGenericValue

public static @Nullable Object readGenericValue(tools.jackson.core.JsonParser p)
                                         throws IOException

Reads the current JSON token as a generic Java value.

Throws:

IOException

toJsonParams

public static String toJsonParams(@Nullable Object params)

Serializes JSON-RPC params to a JSON string: strings pass through as already-serialized JSON, null becomes an empty object, everything else goes through writeValueAsString(java.lang.Object).

writeValueAsString

public static @Nullable String writeValueAsString(@Nullable Object value)

writeJsonValue

public static void writeJsonValue(tools.jackson.core.JsonGenerator gen,
 @Nullable Object value)

Writes a Java object as a JSON value via the given generator.
