Detailed Description

A constrained attribute type that represents a position and a length. The constraint is that the sum of the position and length attributes must be representable by the bsl::size_t type.

size_type

typedef bsl::size_t bdlb::IndexSpan::size_type

Constructor & Destructor Documentation

IndexSpan() [1/3]

bdlb::IndexSpan::IndexSpan ( )

inline

IndexSpan() [2/3]

bdlb::IndexSpan::IndexSpan ( size_type  position, size_type  length  )

inline

Create an IndexSpan object with the specified position and length. The behavior is undefined unless position <= bsl::numeric_limits<size_t>::max() - length.

IndexSpan() [3/3]

bdlb::IndexSpan::IndexSpan ( const IndexSpan &  original )

default

Create an index span having the value of the specified original index span. Note that this trivial copy constructor is generated by the compiler.

~IndexSpan()

bdlb::IndexSpan::~IndexSpan ( )

default

Destroy this index span object. Note that this trivial destructor is generated by the compiler.

Member Function Documentation

BSLMF_NESTED_TRAIT_DECLARATION() [1/2]

bdlb::IndexSpan::BSLMF_NESTED_TRAIT_DECLARATION	(	IndexSpan	,
		bdlb::HasPrintMethod
	)

BSLMF_NESTED_TRAIT_DECLARATION() [2/2]

bdlb::IndexSpan::BSLMF_NESTED_TRAIT_DECLARATION	(	IndexSpan	,
		bsl::is_trivially_copyable
	)

isEmpty()

bool bdlb::IndexSpan::isEmpty ( ) const

inline

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

length()

IndexSpan::size_type bdlb::IndexSpan::length ( ) const

inline

operator=()

IndexSpan & bdlb::IndexSpan::operator= ( const IndexSpan &  rhs )

default

Assign to this index span the value of the specified rhs index span, and return a reference providing modifiable access to this object. Note that this trivial assignment operation is generated by the compiler.

position()

IndexSpan::size_type bdlb::IndexSpan::position ( ) const

inline

print()

bsl::ostream & bdlb::IndexSpan::print	(	bsl::ostream &	stream,
		int	level = 0,
		int	spacesPerLevel = 4
	)		const

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.
