---

Creates a new instance with given parameter.

constructor Create(aCollection: TCollection)

Parameters:

• aCollection: collection

Will create and return a second copy of the Array. The new instance will be a deep copy of the original array; if the members are structs, binaries or arrays themselves, they too will be duplicated as part of the cloning process, so that the new instance and its members will be completely independent of the original class.

Creates and returns a second copy of the struct.

The new instance will be a deep copy of the original struct, all nested members that are arrays, structs or binaries will be duplicated as part of the cloning process, so that the new instance and its members will be completely independent from the original class.

Deserializes current class instance using provided serializer.

procedure ReadComplex(ASerializer: TObject)

Parameters:

Resizes the array to the specified size.

Since arrays are not a very dynamic data structure, repeatedly adding single elements can be a costly procedure, since memory needs to be reallocated for the grown array with each addittion. If the final size of the array is known in advance, it will perform better if you size it to the proper count in advance, and then simply fill the new vacancies.
