Binary :: mid - Get data section from binary data block

The function returns abinary data block containing a data section from the current binary data block.

Return value: Binary data block handle ( odaba::Binary & )

Constant reference to a binary data block handle, which may contain binary data up to 2 GB.

Implementation overview

Get data limited data section
Binary :: mid ( iPosition, iCount )
Get remaining part of binary data block
Binary :: mid ( iPosition )

Implementation details

Get data limited data section
odaba::Binary Binary :: mid ( int32 iPosition, int32 iCount )

The function returns a data section from the current data block beginning at position iPosition.

When there are less than iCount bytes available in the data block, or when iCount is -1, the function returns remaining data after specified position. When passing 0 in iCount the function returns an empty data block.
- iPosition - Position in collection
  The position of an element in a collection is beginning with 0 for the first element.
- iCount - Number of items
  The value contains the number of items to be processed or stored in a collection.

Get remaining part of binary data block
odaba::Binary Binary :: mid ( int32 iPosition )

The function returns the remaining part of the current data block beginning at iPosition.
- iPosition - Position in collection
  The position of an element in a collection is beginning with 0 for the first element.
