Detailed Description

template<class Block, class BlockSize>
class OnixS::CME::MDH::BinaryFields< Block, BlockSize >

Exposes base services to access fields stored in SBE-encoded block of memory. Class represents an abstraction, instance construction available through descendants implementing actual access to encoded data.

Member Function Documentation

Decimal decimal ( BlockSize  offset) const
inlineprotected

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

Definition at line 250 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 273 of file BinaryMessage.h.

bool decimal ( Decimal &  value,
BlockSize  offset,
const NullValue &  null,
SchemaVersion  since 
) 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.

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.

Definition at line 314 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 160 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 189 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 229 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 336 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 362 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.
