Member Function Documentation

Decimal decimal ( BlockSize  offset) const
inlineprotected

Returns value of a field by its offset converted into a decimal.

Definition at line 126 of file BinaryMessage.h.

bool decimal ( Decimal &  value,
BlockSize  offset,
const NullValue &  null 
) const
inlineprotected

Provides access to a value of an optional field by its offset.

The result is converted into decimal.

Returned result indicates whether field is present in given field block and its value was copied into a given parameter-variable.

Definition at line 146 of file BinaryMessage.h.

Enumeration::Enum enumeration ( BlockSize  offset) const
inlineprotected

Returns value of a field by its offset.

Given function serves as specialization of general case for fields of enumeration type.

Definition at line 212 of file BinaryMessage.h.

bool enumeration ( typename Enumeration::Enum &  value,
BlockSize  offset,
const NullValue &  null 
) const
inlineprotected

Provides access to value of an optional field by its offset.

Given function serves as specialization of general case for fields of enumeration type.

Definition at line 241 of file BinaryMessage.h.

bool enumeration ( typename Enumeration::Enum &  value,
BlockSize  offset,
const NullValue &  null,
SchemaVersion  since 
) const
inlineprotected

Provides access to value of an optional field by its offset.

Given function serves as specialization of general case for fields of enumeration type.

Definition at line 281 of file BinaryMessage.h.

StrRef fixedStr ( BlockSize  offset) const
inlineprotected

Provides access to string field by its offset.

Given function serves as specialization of general case for fields of string type.

Definition at line 304 of file BinaryMessage.h.

StrRef fixedStr ( BlockSize  offset,
SchemaVersion  since 
) const
inlineprotected

Provides access to an optional field of string type by its offset.

Given function serves as specialization of general case for fields of string type.

Definition at line 330 of file BinaryMessage.h.

bool fixedStr ( StrRef &  value,
BlockSize  offset 
) const
inlineprotected

Provides access to an optional field of string type by its offset.

Given function serves as specialization of general case for fields of string type.

Definition at line 353 of file BinaryMessage.h.

const FieldValue& ordinary ( BlockSize  offset) const
inlineprotected

Returns value of a field by its offset.

Definition at line 70 of file BinaryMessage.h.

bool ordinary ( FieldValue &  value,
BlockSize  offset,
const NullValue &  null 
) const
inlineprotected

Provides access to a value of an optional field by its offset.

Returned result indicates whether field is present in given field block and its value was copied into a given parameter-variable.

Definition at line 101 of file BinaryMessage.h.

bool ordinary ( FieldValue &  value,
BlockSize  offset,
const NullValue &  null,
SchemaVersion  since 
) const
inlineprotected

Provides access to a value of an optional field by its offset.

Returned result indicates whether field is present in given field block and its value was copied into a given parameter-variable.

Field may not be present in earlier versions of binary message and thus its value may not be available. For this reason, parameter indicating version of data assumed is required to access the field.
