Constructor & Destructor Documentation

template<typename T>

UT_Array< T >::UT_Array ( const UT_Array< T > &  a )

explicit

Copy constructor. It duplicates the data. It's marked explicit so that it's not accidentally passed by value. You can always pass by reference and then copy it, if needed. If you have a line like: UT_Array<int> a = otherarray; and it really does need to copy instead of referencing, you can rewrite it as: UT_Array<int> a(otherarray);

Definition at line 38 of file UT_ArrayImpl.h.

template<typename T>

UT_Array< T >::UT_Array

(

UT_Array< T > &&

)

Move constructor. Steals the working data from the original.

template<class T>

UT_Array< T >::UT_Array ( exint  capacity, exint  size  )

Definition at line 1221 of file UT_ArrayImpl.h.

template<class T>

T* UT_Array< T >::aliasArray ( T *  newdata )

inline

This method allows you to swap in a new raw T array, which must be the same size as myCapacity. Use caution with this method.

Definition at line 630 of file UT_Array.h.

template<class T>

exint UT_Array< T >::append ( void  )

inline

Append an element to the current elements and return its index in the array, or insert the element at a specified position; if necessary, insert() grows the array to accommodate the element. The insert methods use the assignment operator '=' to place the element into the right spot; be aware that '=' works differently on objects and pointers. The test for duplicates uses the logical equal operator '=='; as with '=', the behaviour of the equality operator on pointers versus objects is not the same. Use the subscript operators instead of insert() if you are appending to the array, or if you don't mind overwriting the element already inserted at the given index.

Examples:

euclid/EUC_Expression.C, OPUI/OPUI_HighlightBadge.C, and OPUI/OPUI_MemUsageTextBadge.C.

template<typename T >

template<typename S >

exint UT_Array< T >::appendImpl ( S &&  s )

protected

Implements both append(const T &) and append(T &&) via perfect forwarding. Unlike the variadic emplace_back(), its argument may be a reference to another element in the array.

template<typename T>

exint UT_Array< T >::apply	(	int(*)(T &t, void *d)	applyFct,
		void *	d
	)

Apply a user-defined function to each element of the array as int as the function returns zero. If applyFct returns 1, apply() stops traversing the list and returns the current index; otherwise, apply() returns the size.

template<class T>

void UT_Array< T >::bumpCapacity ( exint  mincapacity )

inline

If the capacity is smaller than mincapacity, expand the array to at least mincapacity and to at least a constant factor of the array's previous capacity, to avoid having a linear number of reallocations in a linear number of calls to bumpCapacity.

Definition at line 417 of file UT_Array.h.

template<class T>

void UT_Array< T >::bumpEntries ( exint  newsize )

NOTE: bumpEntries() will be deprecated in favour of bumpSize() in a future version.

Definition at line 441 of file UT_Array.h.

template<class T>

void UT_Array< T >::bumpSize ( exint  newsize )

inline

First bumpCapacity to ensure that there's space for newsize, expanding either not at all or by at least a constant factor of the array's previous capacity, then set the size to newsize.

Definition at line 434 of file UT_Array.h.

template<class T>

)

Adds a new element to the array (resizing if necessary) and forwards the given arguments to T's constructor. NOTE: Unlike append(), the arguments cannot reference any existing elements in the array. Checking for and handling such cases would remove most of the performance gain versus append(T(...)). Debug builds will assert that the arguments are valid.

Definition at line 537 of file UT_ArrayImpl.h.

template<typename T>

exint UT_Array< T >::find	(	const T &	t,
		exint	s = 0
	)		const

Search for t in one of two ways: linearly using the '==' operator, or binary using the function specified in the parameter list respectively. find() returns the index of the matching element or (exint)-1. Parameter s indicates the index the search should start at.

template<typename T>

exint UT_Array< T >::findAndRemove

(

Remove one element from the array given the element itself or its position in the list, and fill the gap by shifting the elements down by one position. Return the index of the element remove or -1 if the value was not found.

Definition at line 500 of file UT_ArrayImpl.h.

template<class T>

T UT_Array< T >::forcedGet ( exint  i ) const

Merge the given array into us. If direction is -1, then it assumes us and 'other' are both already sorted in descending order. Similarly, +1 means ascending. If allow_dups is false, then it further assumes that both arrays have no duplicates and will produce a result that also has no duplicates. More work will be needed if you want allow_dups to mean remove duplicates

void UT_Array< T >::stableSort ( ComparatorBool  is_less )

inline

stableSort is both stable, so keeps equal elements in the same order (note this is very useful for compatibility between compilers) and templated. Either use a bool sort function or make a utility class with bool operator()(const T a, const T b) the utility class lets you bind data to avoid globals. The comparator returns true if a must occur before b in the list. For sorting ascending, this is a less than operation.

inline

Sort indices array by the values indexed into this array using a stable sorting algorithm. To reorder the array in such a way that it would be sorted, or another array to be reordered the same way, include UT_Permute.h and use: UTinversePermute(values.getArray(), indices.getArray(), values.size()); The ComparatorBool uses the less-than semantics. I must be an integer type.
