HxCollection Class¶

class HxCollection¶

Value type for collection expressions (lists or sets). Such value is obtained with HxExpression::getCollectionValue() or HxSolution::getCollectionValue(). It represents a reference to the value of a variable and the value of this variable is modified when the HxCollection object is modified.

Since:: 5.5

Summary¶

Functions¶
`add`	Adds the given value to this collection.
`clear`	Removes all values of this collection.
`count`	Returns the number of values in the collection.
`get`	Gets the value at the given position.
`contains`	Returns true if the collection contains the given value, false otherwise.
`isUndefined`	Returns true if the collection is undefined.
`toString`	Returns a string representation of the values in the collection in the format { val0, val1, ..., valN }.

Overloaded operators¶
`operator[]`	Operator overloading for get.

Functions¶

void HxCollection::add(hxint val)¶

Adds the given value to this collection. Only allowed in state S_Stopped. This function will fail if the given value is outside of the domain of the list/set or if this value is already included in this list/set (keep in mind that a list or a set cannot contain twice the same value).

Parameters:: val – The value to be added.

void HxCollection::clear()¶: Removes all values of this collection. Only allowed in state S_Stopped.

int HxCollection::count() const¶: Returns the number of values in the collection. Values in collections are indexed from 0 to count()-1.

hxint HxCollection::get(int position) const¶

Gets the value at the given position.

Parameters:: position – The considered position (must be non negative and strictly smaller than the number of values in the collection).

bool HxCollection::contains(hxint value) const¶

Returns true if the collection contains the given value, false otherwise.

Parameters:: value – element whose presence in this collection is to be tested

bool HxCollection::isUndefined() const¶

Returns true if the collection is undefined. A collection can be undefined if it is the result of any ill-defined operation (at with out of bounds index or operations on undefined values for instance).

Returns:: True if the collection is undefined.

std::string HxCollection::toString() const¶

Returns a string representation of the values in the collection in the format { val0, val1, ..., valN }.

Returns:: String representation.

Overloaded operators¶

hxint HxCollection::operator[](int position) const¶

Operator overloading for get.

Parameters:: position – The considered position (must be non negative and strictly smaller than the number of values in the collection).
