List of all members.
Detailed Description
This class provides a read-only view to a map of datums (an array of DatumIntMapEntry
objects). It holds the array by a const
pointer and an integral size value. It acts as return value for accessors inside the Datum
class that return a map of Datum
objects. Note that zero-size maps are valid.

Member Typedef Documentation
Constructor & Destructor Documentation
Create a DatumIntMapRef
object having the specified data
of the specified size
and the specified sorted
flag. The behavior is undefined unless 0 != data
or 0 == size
. Note that the pointer to the array is just copied.

Member Function Documentation
Return the element stored at the specified index
position in this map. The behavior is undefined unless index < size()
.
Return pointer to the first element in the map.
bool bdld::DatumIntMapRef::isSorted |
( |
|
) |
const |
Return true
if underlying map is sorted and false
otherwise.
SizeType bdld::DatumIntMapRef::size |
( |
|
) |
const |
Return the size of the map.
const Datum* bdld::DatumIntMapRef::find |
( |
int |
key |
) |
const |
Return a const pointer to the datum having the specified key
, if it exists and 0 otherwise. Note that the find
has order of O(n)
if the data is not sorted based on the keys; if the data is sorted, it has order of O(log(n))
. Also note that if multiple entries with matching keys are present, which matching record is found is unspecified.

Write the value of this object to the specified output stream
in a human-readable format, and return a reference to the modifiable stream
. Optionally specify an initial indentation level
, whose absolute value is incremented recursively for nested objects. If level
is specified, optionally specify spacesPerLevel
, whose absolute value indicates the number of spaces per indentation level for this and all of its nested objects. If level
is negative, suppress indentation of the first line. If spacesPerLevel
is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level
). If stream
is not valid on entry, this operation has no effect. Note that this human-readable format is not fully specified, and can change without notice.
