◆ operator!=() [1/2]
Compares with another instance for inequality.
◆ operator!=() [2/2]
Compares the string presentation for equality with the given text reference.
◆ operator=()
Updates an instance to refer to another field value.
- Warning
- Does NOT perform a deep copy of field values. Just updates a reference to point to the value of other field.
◆ operator==() [1/2]
Compares with another instance for equality.
◆ operator==() [2/2]
Compares the string presentation for equality with given text reference.
◆ swap()
◆ toChar()
| bool toChar |
( |
char & | | ) |
const |
If the value represent a one-char text, copies it into the given variable.
- Returns
- false if the conversion fails (for example, the stored value is the whole number assigned to a field using the OnixS::FIX::FieldSet::setV member).
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toGroup()
| bool toGroup |
( |
Group & | | ) |
const |
If a repeating group is associated with the field, allows to get an instance of it.
- Returns
- false if no group is associated with the field.
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toNumber() [1/6]
Converts the field value into the floating point value.
- Returns
- false if the conversion fails.
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toNumber() [2/6]
| bool toNumber |
( |
Double & | | ) |
const |
Converts the field value into the floating point value.
- Returns
- false if the conversion fails.
- Warning

◆ toNumber() [3/6]
| bool toNumber |
( |
Int32 & | | ) |
const |
Converts the field value into the whole number.
- Returns
- false if the conversion fails.
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toNumber() [4/6]
| bool toNumber |
( |
Int64 & | | ) |
const |
Converts the field value into the whole number.
- Returns
- false if the conversion fails.
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toNumber() [5/6]

( |
UInt32 & | | ) |
const |
Converts the field value into the whole number.
- Returns
- false if the conversion fails.
- Warning
- Due to performance considerations doesn't check whether an instance refers to a valid value. Use the OnixS::FIX::FieldValueRef::operator bool() member to check an instance for a validness.
◆ toNumber() [6/6]
| bool toNumber |
( |
UInt64 & | | ) |
const |
Converts the field value into the whole number.
- Returns
- false if the conversion fails.
- Warning

◆ toString() [1/2]
| std::string toString |
( |
| ) |
const |

Return the string presentation of the field value.
Definition at line 249 of file FieldValueRef.h.
◆ toString() [2/2]
| void toString |
( |
std::string & | | ) |
const |
Appends a copy of a text presentation to the std::string.
◆ toStringRef() [1/2]
If the value represents a text, returns a reference to it.
- Returns
- An empty StringRef if the conversion fails (for example, the stored value is the whole number assigned to a field using the OnixS::FIX::FieldSet::setV member), otherwise - valid StringRef.
- Warning
