Method Detail

createFatal

public static <OPERATION> SubdocOperationResult<OPERATION> createFatal(String path,
                                                                       OPERATION operation,
                                                                       RuntimeException fatal)

Create a SubdocOperationResult that denotes that a fatal Exception occurred when parsing server-side result. The exception can be found as the value, and the status is ResponseStatus.FAILURE.

Parameters:

path - the path looked up.

operation - the type of the operation which result couldn't be parsed.

fatal - the Exception that occurred during response parsing.

Returns:

the fatal LookupResult.

createResult

public static <OPERATION> SubdocOperationResult<OPERATION> createResult(String path,
                                                                        OPERATION operation,
                                                                        ResponseStatus status,
                                                                        Object value)

Create a SubdocOperationResult that corresponds to an operation that should return a content (including null) instead of throwing when calling DocumentFragment.content(String).

Parameters:

path - the path looked up.

operation - the type of operation.

status - the status of the operation.

value - the value of the operation if applicable, null otherwise.

Returns:

the operation result.

createResult

public static <OPERATION> SubdocOperationResult<OPERATION> createResult(String path,
                                                                        OPERATION operation,
                                                                        ResponseStatus status,
                                                                        Object value,
                                                                        byte[] rawValue)

Create a SubdocOperationResult that corresponds to an operation that should return a content (including null) instead of throwing when calling DocumentFragment.content(String). Additionally, the result can also contain a raw byte representation of the same content in serialized form.

Parameters:

path - the path looked up.

operation - the type of operation.

status - the status of the operation.

value - the value of the operation if applicable, null otherwise.

rawValue - the raw byte value of the operation if applicable, null otherwise.

Returns:

the operation result.

createError

public static <OPERATION> SubdocOperationResult<OPERATION> createError(String path,
                                                                       OPERATION operation,
                                                                       ResponseStatus status,
                                                                       CouchbaseException exception)

Create a SubdocOperationResult that correspond to a subdoc-level error, to be thrown by the enclosing DocumentFragment when calling content methods.

Parameters:

path - the path looked up.

operation - the type of operation.

status - the status of the operation.

exception - the exception to throw when trying to access the operation content.

Returns:

the operation result.

path

public String path()

Returns:

the path that was looked up.

operation

public OPERATION operation()

Returns:

the exact kind of lookup that was performed.

status

public ResponseStatus status()

Returns:

the status of the lookup.

exists

public boolean exists()

Returns:

true if the value existed (and might have associated value), false otherwise.

value

public Object value()

Returns: - the value retrieved by a successful GET. - null for an unsuccessful GET (see the status() for details). - true/false for an EXIST (equivalent to exists()). - a RuntimeException if the client side parsing of the result failed (isFatal()).

Returns:

the value

rawValue

public byte[] rawValue()

Returns the serialized form of the value of a successful GET, as an array of bytes, or null for any other case, including when the raw value isn't relevant.

Returns:

the serialized raw value, if available.

isFatal

public boolean isFatal()

Returns:

true if there was a fatal error while processing the result on the client side, in which case value() returns an RuntimeException.

toString

public String toString()

Overrides:

toString in class Object
