Detailed Description

BIT field represented as chars for non-MyISAM tables.

Todo:: The inheritance relationship is backwards since Field_bit is an extended version of Field_bit_as_char and not the other way around. Hence, we should refactor it to fix the hierarchy order.

Member Function Documentation

Field_bit_as_char* Field_bit_as_char::clone ( MEM_ROOT * mem_root ) const [inline, virtual]

Makes a shallow copy of the Field object.

Note:: This member function must be overridden in all concrete subclasses. Several of the Field subclasses are concrete even though they are not leaf classes, so the compiler will not always catch this.

Parameters:

mem_root MEM_ROOT to use for memory allocation.

Return values:

NULL	If memory allocation failed.

Reimplemented from Field_bit.
