class Geo::GeoBitArray

A simple bit array wrapper, stored in an array of u32s.

Functions

Geo::GeoBitArray::~GeoBitArray

public: ~GeoBitArray()

Basic destructor.

void Geo::GeoBitArray::ClearAllItems

public: void ClearAllItems()

Clear all bits.

void Geo::GeoBitArray::ClearItem

public: void ClearItem
(
    s32 itemIdx
)

Clear a bit.

void Geo::GeoBitArray::ClearUp

public: void ClearUp()

Delete any memory to reset to initial empty state.

static s32 Geo::GeoBitArray::ComputeBitArrayLength

public: s32 ComputeBitArrayLength
(
    s32 numItems
)

Compute the length of the s32 array that numItems will require.

s32 Geo::GeoBitArray::CountNumBitsSet

public: s32 CountNumBitsSet() const

Count and return the number of bits set.

Geo::GeoBitArray::GeoBitArray

public: GeoBitArray()

Default constructor.

Geo::GeoBitArray::GeoBitArray

public: GeoBitArray
(
    const GeoBitArray & bitArray
)

Copy constructor.

u32* Geo::GeoBitArray::GetBitArray

public: u32 * GetBitArray()

Read-write access to the bit array itself.

const u32* Geo::GeoBitArray::GetBitArray

public: const u32 * GetBitArray() const

Read-only access to the bit array itself.

s32 Geo::GeoBitArray::GetNumItems

public: s32 GetNumItems() const

Read-only access to num items.

bool Geo::GeoBitArray::Initialise

public: bool Initialise
(
    s32 numItems
)

(Re-)Construct a zeroed bit array for numItems.

'numItems' can be zero but not negative.

Returns

False only if the mem alloc fails.

GeoBitArray& Geo::GeoBitArray::operator=

public: GeoBitArray & operator=
(
    const GeoBitArray & bitArray
)

Assignment from another GeoBitArray.

void Geo::GeoBitArray::SetItem

public: void SetItem
(
    s32 itemIdx
)

Set a bit.

bool Geo::GeoBitArray::TestItem

public: bool TestItem
(
    s32 itemIdx
) const

Test whether a bit has been set.
