Detailed Description

Implements concept of a read-only reference to a FIX field value.

Definition at line 38 of file FieldValueRef.h.

Constructor & Destructor Documentation

FieldValueRef() [1/2]

FieldValueRef

(

)

Uninitialized value.

FieldValueRef() [2/2]

FieldValueRef

(

const FieldValueRef &

other

)

Shallow copy from another one.

Member Function Documentation

operator bool()

operator bool

(

)

const

Indicated whether the instance refers to a valid value.

operator std::string()

operator std::string ( ) const

inline

Return string presentation of the value being referenced.

Definition at line 198 of file FieldValueRef.h.

operator!=() [1/2]

bool operator!=

(

const FieldValueRef &

)

const

Compares with another instance for inequality.

operator!=() [2/2]

bool operator!=

(

const StringRef &

)

const

Compares string presentation for equality with given text reference.

operator=()

FieldValueRef & operator=

(

const FieldValueRef &

)

Updates instance to refer to another field value.

Warning

Does NOT perform deep copy of field values. Just updates reference to point to value of other field.

operator==() [1/2]

bool operator==

(

const FieldValueRef &

)

const

Compares with another instance for equality.

operator==() [2/2]

bool operator==

(

const StringRef &

)

const

Compares string presentation for equality with given text reference.

swap()

void swap	(	FieldValueRef &		)
throw	(	)

toChar()

bool toChar

(

char &

)

const

If value represent one-char text, copies it into given variable.

Returns

false if conversion fails (for example, stored value is whole number assigned to a field using OnixS::FIX::FieldSet::setV member).

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toGroup()

bool toGroup

(

Group &

)

const

If repeating group is associated with field, allows to get instance of it.

Returns

false if no group is associated with field.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toNumber() [1/5]

bool toNumber

(

Decimal &

)

const

Converts field value into floating point value.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toNumber() [2/5]

bool toNumber

(

Int32 &

)

const

Converts field value into whole number.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toNumber() [3/5]

bool toNumber

(

Int64 &

)

const

Converts field value into whole number.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toNumber() [4/5]

bool toNumber

(

UInt32 &

)

const

Converts field value into whole number.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toNumber() [5/5]

bool toNumber

(

UInt64 &

)

const

Converts field value into whole number.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toString() [1/2]

std::string toString ( ) const

inline

Return string presentation of field value.

Definition at line 210 of file FieldValueRef.h.

toString() [2/2]

void toString

(

std::string &

)

const

Appends copy of text presentation to the std::string.

toStringRef()

bool toStringRef

(

StringRef &

)

const

If value represents text, returns reference to it.

Returns

false if conversion fails (for example, stored value is whole number assigned to a field using OnixS::FIX::FieldSet::setV member).

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.

toTimestamp()

bool toTimestamp	(	Timestamp &	,
		TimestampFormat::Enum	= TimestampFormat::YYYYMMDDHHMMSSNsec ) const

Converts field value into timestamp of requested format.

Returns

false if conversion fails.

Warning

Due to performance considerations doesn't check whether instance refers to a valid value. Use OnixS::FIX::FieldValueRef::operator bool() member to check instance for a validness.
