This class provides a mechanism to build a Datum object having an array value in an exception-safe manner.
Declared in <bdld_datumarraybuilder.h>
class DatumArrayBuilder;| Name | Description |
|---|---|
SizeType | SizeType is an alias for an unsigned integral value, representing the capacity or length of a datum array. |

DatumArrayBuilder [constructor] | Constructors |
~DatumArrayBuilder [destructor] | Destroy this object. If this object is holding a Datum array that has not been adopted, then the Datum array is disposed after destroying each of its elements. |
append | Append the specified array values having the specified length to the Datum array being built by this object. The behavior is undefined unless 0 != length && 0 != values and each element in values that needs dynamic memory, is allocated with the same allocator that was used to construct this object. The behavior is also undefined if commit has already been called on this object. |
capacity | Return the capacity of the held Datum array. The behavior is undefined if commit has already been called on this object. Note that similar to the capacity of a vector, the returned capacity has no bearing on the value of the Datum array being constructed, but does indicate at which point additional memory will be required to grow the Datum array being built. |
commit | Return a Datum array value holding the elements supplied to pushBack or append. The caller is responsible for releasing the resources of the returned Datum object. Calling this method indicates that the caller is finished building the datum array and no further values shall be appended. It is undefined behavior to call any method of this object, other than the destructor, after commit has been called. |
get_allocator | Return the allocator used by this object to supply memory. Note that if no allocator was supplied at construction the default allocator in effect at construction is used. |
pushBack | Append the specified value to the Datum array being built by this object. The behavior is undefined if value needs dynamic memory and was allocated using a different allocator than the one used to construct this object. The behavior is also undefined if commit has already been called on this object. |
size | Return the size of the held Datum array. The behavior is undefined if commit has already been called on this object. |
operator BloombergLP::bslmf::NestedTraitDeclaration<DatumArrayBuilder, UsesBslmaAllocator> | Declare that this type uses a bslma allocator. |
