Detailed Description

Allocate positions on a rectangular 2d grid.

Definition at line 88 of file position-allocator.h.

Member Enumeration Documentation

enum ns3::GridPositionAllocator::LayoutType

Determine whether positions are allocated row first or column first.

Enumerator:

ROW_FIRST	In row-first mode, positions are allocated on the first row until N positions have been allocated. Then, the second row located a yMin + yDelta is used to allocate positions.
COLUMN_FIRST	In column-first mode, positions are allocated on the first column until N positions have been allocated. Then, the second column located a xMin + xDelta is used to allocate positions.

Definition at line 96 of file position-allocator.h.

Member Function Documentation

int64_t ns3::GridPositionAllocator::AssignStreams ( int64_t stream )

virtual

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 211 of file position-allocator.cc.

double ns3::GridPositionAllocator::GetDeltaX ( void ) const

Returns: the x interval between two x-consecutive positions.

Definition at line 172 of file position-allocator.cc.

References m_deltaX.

double ns3::GridPositionAllocator::GetDeltaY ( void ) const

Returns: the y interval between two y-consecutive positions.

Definition at line 177 of file position-allocator.cc.

References m_deltaY.

enum GridPositionAllocator::LayoutType ns3::GridPositionAllocator::GetLayoutType ( void ) const

Returns: the currently-selected layout type.

Definition at line 187 of file position-allocator.cc.

References m_layoutType.

double ns3::GridPositionAllocator::GetMinX ( void ) const

Returns: the x coordinate of the first allocated position.

Definition at line 162 of file position-allocator.cc.

References m_xMin.

double ns3::GridPositionAllocator::GetMinY ( void ) const

Returns: the y coordinate of the first allocated position.

Definition at line 167 of file position-allocator.cc.

References m_yMin.

uint32_t ns3::GridPositionAllocator::GetN ( void ) const

Returns: the number of positions to allocate on each row or each column.

Definition at line 182 of file position-allocator.cc.

References m_n.

Vector ns3::GridPositionAllocator::GetNext ( void ) const

virtual

Returns: the next chosen position.

This method must be implement in subclasses.

Implements ns3::PositionAllocator.
