BitBuffer Class Reference

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.

Constructor(s) / Destructor Details:

BitBuffer()

BitBuffer ( uinteger initialCapacity )

inline

Constructor.

Parameters

initialCapacity

The requested initial capacity of the buffer in bits.

Method Details:

Capacity()

virtual uinteger Capacity ( ) const

inlineoverridevirtual

Returns the (currently allocated) capacity.

Returns

The size of the internal storage in bits.

Implements BitBufferBase.

Definition at line 455 of file bitbuffer.hpp.

EnsureCapacity()

virtual bool 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 BitBufferBase.
