Detailed Description

MIDOUBLEARRAY class exists to solve an issue with some OS's that cannot correctly align a buffer of double's on a double boundary.

Not aligning on a double boundary can cause a speed penalty on some platforms. This class creates a buffer that is forced to be double aligned. This is exported from MISYSTEM.DLL and must not be inherited from. Currently DOUBLE_ARRAY<> and POLYLINE classes use this class as their foundation. Thise classes should meet most of your needs.

Member Function Documentation

void MIDOUBLEARRAY::Attach (  MIDOUBLEARRAY &  rhs  )

Attach a MIDOUBLEARRAY to this one and clear out 'rhs'.

void MIDOUBLEARRAY::Free (   )

Free MIDOUBLEARRAY buffer.

int MIDOUBLEARRAY::GetNumReserved (   )  const

Get reserved size of buffer in doubles. Returns: Size of reserved buffer in doubles

double* MIDOUBLEARRAY::GetPointer (   )

Get pointer to internal buffer. DO NOT REALLOCATE OR FREE THIS POINTER, YOU WILL CRASH Returns: Pointer to correctly aligned double array buffer

MIDOUBLEARRAY& MIDOUBLEARRAY::operator= (  const MIDOUBLEARRAY &  rhs  )

Assignment.

ERRVALUE MIDOUBLEARRAY::Reserve (  INT32  NewSize, bool  keepold = false )

Reserve number of doubles in the array.

void MIDOUBLEARRAY::ReserveExc (  INT32  NewSize, bool  keepold = false )

Reserve number of doubles in the array, throws exception if error.

void MIDOUBLEARRAY::Swap (  MIDOUBLEARRAY &  rhs  )

Swap buffers between 'this' and 'rhs'.
