| struct | ConstIterator |
Public Member Functions | |
| plUInt32 | GetCount () const |
| Returns the number of bits that this bitfield stores. | |
| template<typename = void> | |
| void | SetCountUninitialized (plUInt32 uiBitCount) |
| Resizes the Bitfield to hold the given number of bits. This version does NOT initialize new bits! | |
| void | SetCount (plUInt32 uiBitCount, bool bSetNew=false) |
| Resizes the Bitfield to hold the given number of bits. If bSetNew is true, new bits are set to 1, otherwise they are cleared to 0. | |
| bool | IsEmpty () const |
| Returns true, if the bitfield does not store any bits. | |
| bool | IsAnyBitSet (plUInt32 uiFirstBit=0, plUInt32 uiNumBits=0xFFFFFFFF) const |
| Returns true, if the bitfield is not empty and any bit is 1. | |
| bool | IsNoBitSet (plUInt32 uiFirstBit=0, plUInt32 uiNumBits=0xFFFFFFFF) const |
| Returns true, if the bitfield is empty or all bits are set to zero. | |
| bool | AreAllBitsSet (plUInt32 uiFirstBit=0, plUInt32 uiNumBits=0xFFFFFFFF) const |
| Returns true, if the bitfield is not empty and all bits are set to one. | |
| void | Clear () |
| Discards all bits and sets count to zero. | |
| void | SetBit (plUInt32 uiBit) |
| Sets the given bit to 1. | |
| void | ClearBit (plUInt32 uiBit) |
| Clears the given bit to 0. | |
| void | SetBitValue (plUInt32 uiBit, bool bValue) |
| Sets the given bit to 1 or 0 depending on the given value. | |
| bool | IsBitSet (plUInt32 uiBit) const |
| Returns true, if the given bit is set to 1. | |
| void | ClearAllBits () |
| Clears all bits to 0. | |
| void | SetAllBits () |
| Sets all bits to 1. | |
| void | SetBitRange (plUInt32 uiFirstBit, plUInt32 uiNumBits) |
| Sets the range starting at uiFirstBit up to (and including) uiLastBit to 1. | |
| void | ClearBitRange (plUInt32 uiFirstBit, plUInt32 uiNumBits) |
| Clears the range starting at uiFirstBit up to (and including) uiLastBit to 0. | |
| void | Swap (plBitfield< Container > &other) |
| Swaps two bitfields. | |
| ConstIterator | GetIterator () const |
| Returns a constant iterator to the very first set bit. Note that due to the way iterating through bits is accelerated, changes to the bitfield while iterating through the bits has undefined behaviour. | |
| ConstIterator | GetEndIterator () const |
| Returns an invalid iterator. Needed to support range based for loops. | |

A template interface, that turns any array class into a bitfield.
This class provides an interface to work with single bits, to store true/false values. The underlying container is configurable, though it must support random access and a 'SetCount' function and it must use elements of type plUInt32. In most cases a dynamic array should be used. For this case the plDynamicBitfield typedef is already available. There is also an plHybridBitfield typedef.
