Member Function Documentation

size_t fields ( Fields fields) const

Retrieve tags and values of all non-empty fields belonged to the given FieldSet instance.

Parameters
fieldsObject to receive the FieldSet content.
Returns
Number of fields placed to the fields vector.
FieldValueRef get ( Tag  tag) const

Returns reference to a given field value.

Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
Decimal getDecimal ( Tag  tag) const

Returns the field value as a decimal number.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
Group getGroup ( Tag  numberOfInstancesTag) const

Returns reference to a repeating group if underlying field defines length of repeating group.

Parameters
numberOfInstancesTagTag number of the field that defines the number of instances in this repeating group (the NoXXX field).
Exceptions
std::exceptionif no repeating group is associated with given field (tag).
Warning
Returned instance remains valid until field is modified via any of OnixS::FIX::FieldSet::set members.
Int32 getInt32 ( Tag  tag) const

Returns field value as an OnixS::FIX::Int32 value.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
Int64 getInt64 ( Tag  tag) const

Returns field value as an OnixS::FIX::Int64 value.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
Group getOptionalGroup ( Tag  numberOfInstancesTag) const

Returns reference to a repeating group if underlying field defines length of repeating group.

Parameters
numberOfInstancesTagTag number of the field that defines the number of instances in this repeating group (the NoXXX field).
Warning
Returned instance remains valid until field is modified via any of OnixS::FIX::FieldSet::set members.
StringRef getStringRef ( Tag  tag) const

Returns reference to a read-only text chain.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.

Returns the field value as timestamp of requested format.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
UInt32 getUInt32 ( Tag  tag) const

Returns field value as an OnixS::FIX::UInt32 value.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
UInt64 getUInt64 ( Tag  tag) const

Returns field value as an OnixS::FIX::UInt64 value.

Exceptions
std::exceptionif conversion is impossible.
Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
bool hasFlag ( Tag  tag) const

Returns true if the given flag is present and it equals to "Y", otherwise false.

Warning
Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use OnixS::FIX::FieldSet::operator bool() to check whether instance is in valid state.
operator bool ( ) const

Indicates whether instance refers to a valid set of fields.

If given instance doesn't refer to a valid fields set, none of other members must be used.
