CurrentElement

Returns the current item in the enumeration (for CommonInterfaces.IStringIterator ), your "place" in the enumeration. When the iterator is first supplied or when it is     Reset, there is no current element (calling this method in such a case would raise an exception). Only after the first call to the     NextElement method will this method return a value. Unlike the NextElement method which returns a new value every time you call it, this method always returns the same value no matter how many times you call it (until NextElement is called, of course).

This method is part of the CommonInterfaces.IStringIterator interface.

CurrentElementO

Returns the current object item in the enumeration (for CommonInterfaces.IObjectIterator ), your "place" in the enumeration. It returns the Objects property of TStrings. When the iterator is first supplied or when it is     Reset, there is no current element (calling this method in such a case would raise an exception). Only after the first call to the     NextElementO method will this method return a value. Unlike the NextElementO method which returns a new value every time you call it, this method always returns the same value no matter how many times you call it (until NextElementO is called, of course).

This method is part of the CommonInterfaces.IObjectIterator interface.

CurrentElementP

Returns the current item (as a TRSPointerType) in the enumeration (for CommonInterfaces.IIterator), your "place" in the enumeration. It returns the Objects property of TStrings as a TRSPointerType. When the iterator is first supplied or when it is     Reset, there is no current element (calling this method in such a case would raise an exception). Only after the first call to the     NextElementPmethod will this method return a value. Unlike the NextElementP method which returns a new value every time you call it, this method always returns the same value no matter how many times you call it (until NextElementP is called, of course).

This method is part of the CommonInterfaces.IIterator interface.

GetCount

Accessor method for the RSInterfaceCollections.TStringsIterator.Count property.

HasMoreElements

Returns True if there are more elements to retrieve from the enumeration. While this method returns true, the     NextElement/     NextElementO/     NextElementP methods will not raise an exception.

This method is part of the CommonInterfaces.IIterator, CommonInterfaces.IObjectIterator , and CommonInterfaces.IStringIterator interfaces.
 

NextElement

Returns the current item in the enumeration (for CommonInterfaces.IStringIterator ), your "place" in the enumeration. When the iterator is first supplied or when it is     Reset, there is no current element (calling this method in such a case would raise an exception). Only after the first call to the     NextElement method will this method return a value. Unlike the NextElement method which returns a new value every time you call it, this method always returns the same value no matter how many times you call it (until NextElement is called, of course).

This method is part of the CommonInterfaces.IStringIterator interface.

NextElementO

Returns the next object item in the enumeration (Objects property of TStrings). If there are no more items, the method will raise an exception. To check if there are more items, use the     HasMoreElements method. The NextElementO method advances its place in the enumeration and then returns that item. Every call to NextElementO returns a new item (until the end of the enumeration). If you wish to access the current item multiple times in a loop, use the     CurrentElementO method.

This method is part of the CommonInterfaces.IObjectIterator interface.

NextElementP

Returns the next item in the enumeration (Objects property of TStrings as a TRSPointerType). If there are no more items, the method will raise an exception. To check if there are more items, use the     HasMoreElements method. The NextElementP method advances its place in the enumeration and then returns that item. Every call to NextElementP returns a new item (until the end of the enumeration). If you wish to access the current item multiple times in a loop, use the     CurrentElementP method.

This method is part of the CommonInterfaces.IIterator interface.

Reset

Resets the iterator to the beginning of the enumeration.

This method is part of the CommonInterfaces.IIterator, CommonInterfaces.IObjectIterator , and CommonInterfaces.IStringIterator interfaces.
