class Bitmap

Defined at line 16 of file ../../src/ui/lib/escher/util/bitmap.h

Stores boolean values as a tightly-packed bitmap.

Public Methods

void Bitmap (uint32_t * bits, uint32_t bits_size)

The caller is responsible for ensuring that |bits| outlives the Bitmap.

Defined at line 19 of file ../../src/ui/lib/escher/util/bitmap.h

bool Get (uint32_t offset)

Get the value of a single bit.

Defined at line 22 of file ../../src/ui/lib/escher/util/bitmap.h

void Set (uint32_t offset)

Set the value of a single bit to 1.

Defined at line 29 of file ../../src/ui/lib/escher/util/bitmap.h

void Clear (uint32_t offset)

Clear the value of a single bit to 0.

Defined at line 36 of file ../../src/ui/lib/escher/util/bitmap.h

void ClearAll ()

Clear all values in the bitmap to 0.

Defined at line 43 of file ../../src/ui/lib/escher/util/bitmap.h

uint32_t GetSize ()

Return the number of bits that can be held by the Bitmap.

Defined at line 50 of file ../../src/ui/lib/escher/util/bitmap.h

void SetBitStorage (uint32_t * bits, uint32_t bits_size)

Used by subclasses to change the size of the bit storage. It is up to

the caller to copy the old values into the new memory, if desired.
