Enumeration Type Documentation

◆ IngestResult_t

enum IngestResult_t

Data ingest results.

The negative error codes represent actual error in ingesting the data block whereas the positive error codes represent success and other conditions that are not ingest errors like duplicate block is received.

Enumerator
IngestResultFileComplete	The file transfer is complete and the signature check passed.
IngestResultSigCheckFail	The file transfer is complete but the signature check failed.
IngestResultFileCloseFail	There was a problem trying to close the receive file.
IngestResultNullInput	One of the input pointers is NULL.
IngestResultBadFileHandle	The receive file pointer is invalid.
IngestResultUnexpectedBlock	We were asked to ingest a block but were not expecting one.
IngestResultBlockOutOfRange	The received block is out of the expected range.
IngestResultBadData	The data block from the server was malformed.
IngestResultWriteBlockFailed	The PAL layer failed to write the file block.
IngestResultNoDecodeMemory	Memory could not be allocated for decoding .
IngestResultUninitialized	Software BUG: We forgot to set the result code.
IngestResultAccepted_Continue	The block was accepted and we're expecting more.
IngestResultDuplicate_Continue	The block was a duplicate but that's OK. Continue.

◆ DocParseErr_t

enum DocParseErr_t

Generic JSON document parser errors.

Enumerator
DocParseErrUnknown	The error code has not yet been set by a logic path.
DocParseErrNone	No error in parsing the document.
DocParseErrOutOfMemory	We failed to allocate enough dynamic memory for a field.
DocParseErrUserBufferInsuffcient	The supplied user buffer is insufficient for a field.
DocParseErrFieldTypeMismatch	The field type parsed does not match the document model.
DocParseErrBase64Decode	There was an error decoding the base64 data.
DocParseErrInvalidNumChar	There was an invalid character in a numeric value field.
DocParseErrDuplicatesNotAllowed	A duplicate parameter was found in the job document.
DocParseErrMalformedDoc	The document didn't fulfill the model requirements.
DocParseErr_InvalidJSONBuffer	When the JSON is malformed and not parsed correctly.
DocParseErrNullModelPointer	The pointer to the document model was NULL.
DocParseErrNullBodyPointer	The document model's internal body pointer was NULL.
DocParseErrNullDocPointer	The pointer to the JSON document was NULL.
DocParseErrTooManyParams	The document model has more parameters than we can handle.
DocParseErrParamKeyNotInModel	The document model does not include the specified parameter key.
DocParseErrInvalidModelParamType	The document model specified an invalid parameter type.
DocParseErrInvalidToken	The Jasmine token was invalid, producing a NULL pointer.
