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

const double* MIDOUBLEARRAY::GetPointer

(

)

const [inline]

Get const pointer to internal buffer.

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'.
