Constructors

isEmpty

Return true if the length attribute is 0; and return false otherwise.

length

Return the length attribute.

position

Return the position attribute.

print

Format this object to the specified output stream at the (absolute value of) the optionally specified indentation level and return a reference to stream. If level is specified, optionally specify spacesPerLevel, 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.

operator BloombergLP::bslmf::NestedTraitDeclaration<IndexSpan, HasPrintMethod>

Declare that this type is trivially copyable.

Non-Member Functions

Name

Description

operator!=

Return true if the specified lhs and rhs index span objects do not have the same value, and false otherwise. Two index span objects do not have the same value if either their position or length attributes do not compare equal.

operator==

Return true if the specified lhs and rhs index span objects have the same value, and false otherwise. Two index span objects have the same value if their position and length attributes compare equal.
