Description:

A bit buffer using dynamic allocation.

See also

Two alternatives are provided with BitBufferMA, which uses monotonic allocation and BitBufferLocal, which uses local (stack) memory.
For this class, a pretty printer for the GNU debugger is provided.

Method Details:

◆ Capacity()

virtual uinteger alib::bitbuffer::BitBuffer::Capacity ( ) const

inlineoverridevirtual

Returns the (currently allocated) capacity.

Returns: The size of the internal storage in bits.

Implements alib::bitbuffer::BitBufferBase.

Definition at line 441 of file bitbuffer.inl.

◆ EnsureCapacity()

virtual bool alib::bitbuffer::BitBuffer::EnsureCapacity	(	uinteger	bitsRequired,
		BitBufferBase::Index	idx )

inlineoverridevirtual

Checks if the given required storage space is internally reserved. If not, the internal capacity is doubled, or, if more is required, set to the required space.

Parameters

bitsRequired	The number of bits required.
idx	The index of current buffer use.

Returns: true if the space is available or could be made available, false otherwise.

Implements alib::bitbuffer::BitBufferBase.
