static void ValidateBasicTypeFieldValue(const CTempString &str_value, ERR_FieldType field_type, const string &props)

ERR_Action Tokenize(const CTempString raw_line, vector< CTempString > &tokens)

Tokenize the raw line and put the tokens into the tokens vector.

The following rules are going to be applied for the NCBI TSV sources:

ERR_Action Validate(CTempString raw_line, ERR_FieldValidationMode field_validation_mode)

ERR_Action OnNextLine(CTempString raw_line)

ERR_TranslationResult Translate(TFieldNo, const CTempString raw_value, string &translated_value)

Partial specialization of the CRowReaderStream_CharDelimited<...> template for the case when the data...

CTempString implements a light-weight string on top of a storage buffer whose lifetime management is ...

#define END_NCBI_SCOPE

End previously defined NCBI scope.

#define BEGIN_NCBI_SCOPE

Define ncbi namespace.

const char * data(void) const

Return a pointer to the array represented.

bool empty(void) const

Return true if the represented string is empty (i.e., the length is zero)

static bool StartsWith(const CTempString str, const CTempString start, ECase use_case=eCase)

Check if a string starts with a specified prefix value.

size_type size(void) const

Return the length of the represented array.

Uint4 TFieldNo

Field number (zero based)

ERR_FieldValidationMode

Whether to check validity of the fields (names and/or values)

@ eRR_NoFieldValidation

don't validate fields' value and name

ERR_TranslationResult

The Translate() callback result. It is used to translate field values.

@ eRR_UseOriginal

No translation done.

@ eRR_Translated

The value has been translated to another string.

@ eRR_Null

The value has been translated to NULL.

ERR_Action

Delimited stream traits use the ERR_Action members to instruct what should be done next.

@ eRR_Continue_Data

Continue processing this line, in full.

@ eRR_Skip

Skip this line.

@ eRR_Continue_Metadata

Continue processing this line but skip Tokenize() and Translate()

@ eRR_Continue_Comment

Continue processing this line but skip Tokenize() and Translate()

ERR_EventAction

How to react to the potentially disruptive events.

@ eRR_EventAction_Continue

Resume processing.

@ eRR_EventAction_Default

Do some default action.

ERR_EventMode

Indicate whether the "ERR_Event" event (passed to the OnEvent() callback) occured during regular read...

@ eRR_EventMode_Validating

We are performing data validation.

ERR_Event

CRowReader passes such events to the Traits via OnEvent() callback.

@ eRR_Event_SourceEnd

Data source has hit EOF.

@ eRR_Event_SourceBegin

Data source has started or been switched (no reads yet though).

@ eRR_Event_SourceError

Data source has hit an error on read.
