Detailed Description

template<class TYPE>
class bdlc::CompactedArray< TYPE >

This space-efficient, value-semantic array class represents a sequence of TYPE elements. The interface provides functionality similar to a vector<TYPE>, however, modifiable references to individual elements are not provided. This class provides accessors that return iterators that provide non-modifiable access to its elements. The returned iterators, unlike those returned by a vector<TYPE>, are not invalidated upon reallocation.

◆ insert() [1/4]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::insert	(	bsl::size_t	dstIndex,
		const CompactedArray< TYPE > &	srcArray
	)

Insert into this array, at the specified dstIndex, the elements from the specified srcArray, shifting any elements originally at or above dstIndex up by srcArray.length() index positions. The behavior is undefined unless dstIndex <= length(). Note that if this array and srcArray are the same, the behavior is as if a copy of srcArray were passed.

◆ insert() [2/4]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::insert	(	bsl::size_t	dstIndex,
		const CompactedArray< TYPE > &	srcArray,
		bsl::size_t	srcIndex,
		bsl::size_t	numElements
	)

Insert into this array, at the specified dstIndex, the specified numElements starting at the specified srcIndex in the specified srcArray. Elements having an index greater than or equal to dstIndex before the insertion are shifted up by numElements index positions. The behavior is undefined unless dstIndex <= length() and srcIndex + numElements <= srcArray.length(). Note that if this array and srcArray are the same, the behavior is as if a copy of srcArray were passed.

◆ insert() [3/4]

◆ insert() [4/4]

template<class TYPE >

CompactedArray< TYPE >::const_iterator bdlc::CompactedArray< TYPE >::insert	(	const_iterator	dst,
		const TYPE &	value
	)

inline

Insert into this array, at the specified dst, an element having the specified value, shifting any elements originally at or above dst up by one index position. Return an iterator to the newly inserted element. The behavior is undefined unless dst is an iterator over this array.

◆ isEmpty()

template<class TYPE >

inline

Return true if there are no elements in this array, and false otherwise.

◆ isEqual()

template<class TYPE >

bool bdlc::CompactedArray< TYPE >::isEqual ( const CompactedArray< TYPE > & other ) const

inline

Return true if this and the specified other array have the same value, and false otherwise. Two CompactedArray arrays have the same value if they have the same length, and all corresponding elements (those at the same indices) have the same value.

◆ length()

template<class TYPE >

bsl::size_t bdlc::CompactedArray< TYPE >::length ( ) const

inline

◆ operator=()

template<class TYPE >

CompactedArray< TYPE > & bdlc::CompactedArray< TYPE >::operator= ( const CompactedArray< TYPE > & rhs )

◆ operator[]()

template<class TYPE >

const TYPE & bdlc::CompactedArray< TYPE >::operator[] ( bsl::size_t index ) const

inline

Return a const reference to the element at the specified index in this array. The behavior is undefined unless index < length().

◆ pop_back()

template<class TYPE >

void bdlc::CompactedArray< TYPE >::pop_back ( )

Remove the last element from this array. The behavior is undefined unless 0 < length().

◆ print()

template<class TYPE >

bsl::ostream & bdlc::CompactedArray< TYPE >::print	(	bsl::ostream &	stream,
		int	level = `0`,
		int	spacesPerLevel = `4`
	)		const

Write the value of this array to the specified output stream in a human-readable format, and return a reference to stream. Optionally specify an initial indentation level, whose absolute value is incremented recursively for nested arrays. 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 arrays. If level 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 the format is not fully specified, and can change without notice.

◆ push_back()

template<class TYPE >

void bdlc::CompactedArray< TYPE >::push_back ( const TYPE & value )

inline

◆ remove() [1/3]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::remove ( bsl::size_t dstIndex )

inline

Remove from this array the element at the specified dstIndex. Each element having an index greater than dstIndex before the removal is shifted down by one index position. The behavior is undefined unless dstIndex < length().

◆ remove() [2/3]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::remove	(	bsl::size_t	dstIndex,
		bsl::size_t	numElements
	)

◆ remove() [3/3]

template<class TYPE >

CompactedArray< TYPE >::const_iterator bdlc::CompactedArray< TYPE >::remove	(	const_iterator	dstFirst,
		const_iterator	dstLast
	)

inline

Remove from this array the elements starting at the specified dstFirst iterator up to, but not including, the specified dstLast iterator. Each element at or above dstLast before the removal is shifted down by dstLast - dstFirst index positions. Return an iterator to the new position of the element that was referred to by dstLast, or end() if dstLast == end(). The behavior is undefined unless dstFirst and dstLast are iterators over this array, and dstFirst <= dstLast.

◆ removeAll()

template<class TYPE >

void bdlc::CompactedArray< TYPE >::removeAll ( )

◆ replace() [1/2]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::replace	(	bsl::size_t	dstIndex,
		const CompactedArray< TYPE > &	srcArray,
		bsl::size_t	srcIndex,
		bsl::size_t	numElements
	)

Change the values of the specified numElements starting at the specified dstIndex in this array to those of the numElements starting at the specified srcIndex in the specified srcArray. The behavior is undefined unless srcIndex + numElements <= srcArray.length() and dstIndex + numElements <= length(). Note that if this array and srcArray are the same, the behavior is as if a copy of srcArray were passed.

◆ replace() [2/2]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::replace	(	bsl::size_t	dstIndex,
		const TYPE &	value
	)

Change the value of the element at the specified dstIndex in this array to the specified value. The behavior is undefined unless dstIndex < length().

◆ reserveCapacity() [1/2]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::reserveCapacity ( bsl::size_t numElements )

Make the capacity of this array at least the specified numElements, assuming the number of unique elements within this array does not increase. This method has no effect if the current capacity meets or exceeds the required capacity. The behavior is undefined unless false == isEmpty() || 0 == numElements. Note that the assumption of not increasing the number of unique elements implies the need for the narrow contract.

◆ reserveCapacity() [2/2]

template<class TYPE >

void bdlc::CompactedArray< TYPE >::reserveCapacity	(	bsl::size_t	numElements,
		bsl::size_t	numUniqueElements
	)

Make the capacity of this array at least the specified numElements, assuming the number of unique elements in this array does not exceed the greater of the specified numUniqueElements and uniqueLength(). This method has no effect if the current capacity meets or exceeds the required capacity. The behavior is undefined unless numUniqueElements <= numElements and 0 < numUniqueElements || 0 == numElements.

◆ resize()

template<class TYPE >

void bdlc::CompactedArray< TYPE >::resize ( bsl::size_t numElements )

Set the length of this array to the specified numElements. If numElements > length(), the added elements are initialized to TYPE().

◆ swap()

template<class TYPE >

void bdlc::CompactedArray< TYPE >::swap ( CompactedArray< TYPE > & other )

Efficiently exchange the value of this array with the value of the specified other array. This method provides the no-throw exception-safety guarantee. The behavior is undefined unless this array was created with the same allocator as other.

◆ uniqueElement()

template<class TYPE >

const TYPE & bdlc::CompactedArray< TYPE >::uniqueElement ( bsl::size_t index ) const

inline

Return a const reference to the element at the specified index within the sorted sequence of unique element values in this object. The behavior is undefined unless index < uniqueLength(). Note that uniqueElement(index) and operator@ref index can return different objects.

◆ uniqueLength()

template<class TYPE >

bsl::size_t bdlc::CompactedArray< TYPE >::uniqueLength ( ) const

inline
