Member Function Documentation

bool GClasses::GBitTable::areAllClear

(

size_t

count

)

Returns true iff the first "count" bits are clear.

bool GClasses::GBitTable::areAllSet

(

size_t

count

)

Returns true iff the first "count" bits are set. (Note that for most applications, it is more efficient to simply maintain a count of the number of bits that are set than to call this method.)

bool GClasses::GBitTable::bit

(

size_t

index

)

Returns the bit at index.

void GClasses::GBitTable::clearAll

(

)

Sets all bits to false.

bool GClasses::GBitTable::equals

(

GBitTable *

that

)

Returns true iff the bit tables are exactly equal. (Behavior is undefined if the tables are not the same size.)

GBitTable& GClasses::GBitTable::operator=

(

const GBitTable &

o

)

Operator=.

void GClasses::GBitTable::set

(

size_t

index

)

Sets the bit at index.

void GClasses::GBitTable::setAll

(

)

Sets all bits to true.

static void GClasses::GBitTable::test ( )

static

Performs unit tests for this class. Throws an exception if there is a failure.

void GClasses::GBitTable::toggle

(

size_t

index

)

Toggles the bit at index.

void GClasses::GBitTable::unset

(

size_t

index

)

Clears the bit at index.
