Field Details:

◆ ma

MonoAllocator& alib::bitbuffer::BitBufferMA::ma

protected

The monotonic allocator used internally to allocate the storage. This is provided with construction.

Definition at line 477 of file bitbuffer.inl.

◆ storage

StdVectorMono<TStorage> alib::bitbuffer::BitBufferMA::storage

protected

The vector that holds the data.

Definition at line 480 of file bitbuffer.inl.

Constructor(s) / Destructor Details:

◆ BitBufferMA()

alib::bitbuffer::BitBufferMA::BitBufferMA	(	MonoAllocator &	monoAllocator,
		uinteger	initialCapacity )

inline

Constructor taking an external monotonic allocator and the initial capacity.

Parameters

monoAllocator	A reference to a monotonic allocator to use to allocate buffer storage data.
initialCapacity	The requested initial capacity of the buffer in bits.

Definition at line 489 of file bitbuffer.inl.

Here is the call graph for this function:

Method Details:

◆ Capacity()

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

inlineoverridevirtual

Returns the (currently allocated) capacity.

Returns: The size of the internal storage in bits.

Implements alib::bitbuffer::BitBufferBase.

Definition at line 501 of file bitbuffer.inl.

◆ EnsureCapacity()

virtual bool alib::bitbuffer::BitBufferMA::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 divided 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.

Definition at line 515 of file bitbuffer.inl.

Here is the call graph for this function:

◆ GetAllocator()

MonoAllocator & alib::bitbuffer::BitBufferMA::GetAllocator ( )

inline

Returns the internal monotonic allocator for external use.

Returns: The monotonic allocator given on construction.
