Detailed Description

Allocate positions from a deterministic list specified by the user.

The first call to ListPositionAllocator::GetNext will return the first element of the list, the second call, the second element, and so on.

Member Function Documentation

◆ Add() [1/2]

void ns3::ListPositionAllocator::Add	(	const std::string	filePath,
		double	defaultZ = 0,
		char	delimiter = ',' )

Add the positions listed in a file.

The file should be a simple text file, with one position per line, either X and Y, or X, Y and Z, in meters. The delimiter can be any character, such as ',' or '\t'; the default is a comma ','.

The file is read using CsvReader, which explains how comments and whitespace are handled.

Parameters

[in]	filePath	The path to the input file.
[in]	defaultZ	The default Z value to use when reading files with only X and Y positions.
[in]	delimiter	The delimiter character; see CsvReader.

Here is the call graph for this function:

◆ Add() [2/2]

void ns3::ListPositionAllocator::Add ( Vector v )

Add a position to the list of positions.

Parameters

v	the position to append at the end of the list of positions to return from GetNext.

Here is the caller graph for this function:

◆ AssignStreams()

int64_t ns3::ListPositionAllocator::AssignStreams ( int64_t stream )

overridevirtual

Assign a fixed random variable stream number to the random variables used by this model.

Return the number of streams (possibly zero) that have been assigned.

This method must be implement in subclasses.

Parameters

stream first stream index to use

Returns: the number of stream indices assigned by this model

Implements ns3::PositionAllocator.

Definition at line 123 of file position-allocator.cc.

◆ GetNext()

Vector ns3::ListPositionAllocator::GetNext ( ) const

overridevirtual

Returns: the next chosen position.

This method must be implement in subclasses.

Implements ns3::PositionAllocator.

Definition at line 111 of file position-allocator.cc.

References m_current, and m_positions.

◆ GetSize()

uint32_t ns3::ListPositionAllocator::GetSize ( ) const

Return the number of positions stored.

Note that this will not change based on calling GetNext(), as the number of positions is not altered by calling GetNext ().

Returns: the number of positions stored

Definition at line 129 of file position-allocator.cc.

References m_positions.

◆ GetTypeId()

TypeId ns3::ListPositionAllocator::GetTypeId ( )

static

Register this type with the TypeId system.

Returns: the object TypeId
