Member Function Documentation

◆ Add()

template<typename T >
int32_t System::Collections::CollectionBase< T >::ListImpl::Add ( const T &  value)
inline

Adds a element to the end of the collection.

Parameters
valueThe element to be added to the end of the collection.
Returns
The collection index at which the value has been added.
Exceptions
NotSupportedExceptionThe collection is read-only. -or- The collection has a fixed size.

◆ Contains()

template<typename T >
bool System::Collections::CollectionBase< T >::ListImpl::Contains ( const T &  value)
inline

Determines whether the collection contains a specific element.

Parameters
valueThe element to locate in the collection.
Returns
true if the collection contains the specified value; otherwise, false.

◆ CopyTo()

template<typename T >
void System::Collections::CollectionBase< T >::ListImpl::CopyTo ( const ArrayPtr< T > &  array,
int32_t  index 
)
inline

Copies the entire collection to a compatible one-dimensional Array, starting at the specified index of the target array.

Parameters
arrayThe one-dimensional Array that is the destination of the elements copied from the collection. The Array must have zero-based indexing.
indexThe zero-based index in array at which copying begins.
Exceptions
ArgumentNullExceptionarray is nullptr.
ArgumentOutOfRangeExceptionindex is less than zero.
ArgumentExceptionarray is multidimensional. -or- The number of elements in the collection is greater than the available space from index to the end of the destination array.

◆ idx_get()

template<typename T >
T System::Collections::CollectionBase< T >::ListImpl::idx_get ( int32_t  index)
inline

Returns the element at the specified index.

Parameters
indexThe zero-based index of the element to get or set.
Returns
The element at the specified index.
Exceptions
ArgumentOutOfRangeExceptionindex is less than zero. -or- index is equal to or greater than CollectionBase::get_Count.

◆ idx_set()

template<typename T >
void System::Collections::CollectionBase< T >::ListImpl::idx_set ( int32_t  index,
value 
)
inline

Sets the element at the specified index.

Parameters
indexThe zero-based index of the element to get or set.
valueThe element to set.
Exceptions
ArgumentOutOfRangeExceptionindex is less than zero. -or- index is equal to or greater than CollectionBase::get_Count.

◆ IndexOf()

template<typename T >
int32_t System::Collections::CollectionBase< T >::ListImpl::IndexOf ( const T &  value)
inline

Searches for the specified element and returns the zero-based index of the first occurrence within the entire collection.

Parameters
valueThe element to locate in the collection.
Returns
The zero-based index of the first occurrence of value within the entire collection, if found; otherwise, -1.

◆ Insert()

template<typename T >
void System::Collections::CollectionBase< T >::ListImpl::Insert ( int32_t  index,
const T &  value 
)
inline

Inserts an element into the collection at the specified index.

Parameters
indexThe zero-based index at which value should be inserted.
valueThe element to insert.
Exceptions
ArgumentOutOfRangeExceptionindex is less than zero. -or- index is greater than CollectionBase::Count.
NotSupportedExceptionThe collection is read-only. -or- The collection has a fixed size.

◆ Remove()

template<typename T >
void System::Collections::CollectionBase< T >::ListImpl::Remove ( const T &  value)
inline

Removes the first occurrence of a specific element from the collection.

Parameters
valueThe element to remove from the collection.
Exceptions
ArgumentExceptionThe value parameter was not found in the collection.
NotSupportedExceptionThe collection is read-only. -or- The collection has a fixed size.
