Buffer suitable for DMA transfers
include "Ravl/OS/DMABuffer.hh"
User Level:Advanced
In Scope:RavlN

Parent Classes: Methods:
DMABufferC(UIntT size,UIntT align = 64)
Construct an aligned buffer of 'size' elements.
- alignment must be a power of 2.

- This does not initalise the elements of the buffer, and should only be used for trivial objects.

Default constructor.
Creates an invalid handle.

#include "Ravl/Buffer.hh"
UIntT Size() const
Access size of buffer.

DataT * ReferenceElm() const
Returns the pointer to the reference element of the attached buffer.
The reference element need not to be the valid element of the buffer.

void Fill(const DataT & val)
Fill buffer with value.

const SizeBufferAccessC<DataT> & BufferAccess() const
Access buffer.

operator SizeBufferAccessC<DataT> &() const
Access as a size buffer.
I don't like this, but it gets around an irritating warning from gcc.

#include "Ravl/RCHandleV.hh"
bool Save(ostream & out) const
Save to stream 'out'.

bool Save(BinOStreamC & out) const
Save to binary stream 'out'.

RCAbstractC Abstract()
Create an abstract handle.

istream & operator >>(istream & strm,RCHandleVC<BufferBodyC<DataT>> & obj)

BinIStreamC & operator >>(BinIStreamC & strm,RCHandleVC<BufferBodyC<DataT>> & obj)

#include "Ravl/RefCounter.hh"
const RCHandleC<BufferBodyC<DataT>> & operator =(const RCHandleC<BufferBodyC<DataT>> & oth)
Assign handle.

RCHandleC<BufferBodyC<DataT>> DeepCopy(UIntT levels = ((UIntT))) const
Do a deep copy of the object.

bool operator ==(const RCHandleC<BufferBodyC<DataT>> & oth) const
Are handles to the same object ?

bool operator !=(const RCHandleC<BufferBodyC<DataT>> & oth) const
Are handles to different objects ?

UIntT Hash() const
Default hash function.
This hashes on the address of the body.

bool IsValid() const
Test if this is a valid handle.

void Invalidate()
Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const
Is handle of given type ?

void CheckHandleType(const DT & dummy) const
Check handle type. Throw an expception if not.

UIntT References() const
Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<BufferBodyC<DataT>> & obj)

istream & operator >>(istream & strm,RCHandleC<BufferBodyC<DataT>> & obj)
