== Static Member Functions

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bsls/Alignment/calculateAlignmentFromSize.adoc[`calculateAlignmentFromSize`] 
| Calculate a usable alignment for an object of the specified `size`.
| xref:BloombergLP/bsls/Alignment/calculateAlignmentOffset.adoc[`calculateAlignmentOffset`] 
| Return the byte offset needed to align the specified `address`.
| xref:BloombergLP/bsls/Alignment/is2ByteAligned.adoc[`is2ByteAligned`] 
| Return `true` if the specified `address` is aligned on a 2‐byte boundary (i.e., the integer value of `address` is divisible by 2), and `false` otherwise.
| xref:BloombergLP/bsls/Alignment/is4ByteAligned.adoc[`is4ByteAligned`] 
| Return `true` if the specified `address` is aligned on a 4‐byte boundary (i.e., the integer value of `address` is divisible by 4), and `false` otherwise.
| xref:BloombergLP/bsls/Alignment/is8ByteAligned.adoc[`is8ByteAligned`] 
| Return `true` if the specified `address` is aligned on an 8‐byte boundary (i.e., the integer value of `address` is divisible by 8), and `false` otherwise.
| xref:BloombergLP/bsls/Alignment/toAscii.adoc[`toAscii`] 
| Return the string representation of the specified enumerator `value`.
