StringValue() [2/2]

String ns3::StringValue::StringValue

(

const std::string &

value

)

Copy constructor.

Parameters

[in]

value

The String value to copy.

Definition at line 31 of file string.cc.

Member Function Documentation

Copy()

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

overridevirtual

Returns

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

Implements ns3::AttributeValue.

Definition at line 31 of file string.cc.

DeserializeFromString()

bool ns3::StringValue::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()

std::string ns3::StringValue::Get

(

)

const

Returns

The String value.

Here is the caller graph for this function:

GetAccessor()

template<typename T >

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

inline

Access the String value as type T.

Template Parameters

T	[explicit] The type to cast to.

Parameters

[out]

value

The String value, as type T.

Returns

true.

Definition at line 56 of file string.h.

SerializeToString()

std::string ns3::StringValue::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.

Definition at line 31 of file string.cc.

Set()

void ns3::StringValue::Set

(

const std::string &

value

)

Set the value.

Parameters

[in]

value

The value to adopt.
