DoubleValue() [2/2]

Constructor.

Parameters

[in]

value

The Double value to use.

Member Function Documentation

Copy()

Ptr< AttributeValue > ns3::DoubleValue::Copy ( ) const

overridevirtual

Returns

a deep copy of this class, wrapped into an Attribute object.

Implements ns3::AttributeValue.

Definition at line 37 of file double.cc.

DeserializeFromString()

bool ns3::DoubleValue::DeserializeFromString ( std::string  value, Ptr< const AttributeChecker >  checker  )

overridevirtual

Parameters

[in]	value	A string representation of the value
[in]	checker	A pointer to the checker associated to the attribute.

Returns

true if the input string was correctly-formatted and could be successfully deserialized, false otherwise.

Upon return of this function, this AttributeValue instance contains the deserialized value. In most cases, this method will not make any use of the checker argument. However, in a very limited set of cases, the checker argument is needed to perform proper serialization. A nice example of code which needs it is the EnumValue::SerializeToString code.

Implements ns3::AttributeValue.

Get()

double ns3::DoubleValue::Get

(

)

const

Returns

The Double value.

Here is the caller graph for this function:

GetAccessor()

template<typename T >

bool ns3::DoubleValue::GetAccessor ( T &  value ) const

inline

Access the Double value as type T.

Template Parameters

T	[explicit] The type to cast to.

Parameters

[out]

value

The Double value, as type T.

Returns

true.

Definition at line 42 of file double.h.

SerializeToString()

std::string ns3::DoubleValue::SerializeToString ( Ptr< const AttributeChecker >  checker ) const

overridevirtual

Parameters

[in]

checker

The checker associated to the attribute

Returns

A string representation of this value.

In most cases, this method will not make any use of the checker argument. However, in a very limited set of cases, the checker argument is needed to perform proper serialization. A nice example of code which needs it is the EnumValue::SerializeToString code.

Implements ns3::AttributeValue.

Set()

void ns3::DoubleValue::Set

(

const double &

value

)

Set the value.

Parameters

[in]

value

The value to adopt.
