SizeGuess

The expected size of the KeyMap

Description:

This is attribute gives an estimate of the number of entries that will be stored in the KeyMap. It is used to tune the internal properties of the KeyMap for speed and efficiency. A larger value will result in faster access at the expense of increased memory requirements. However if the SizeGuess value is much larger than the actual size of the KeyMap, then there will be little, if any, speed gained by making the SizeGuess even larger. The default value is 300.

The value of this attribute can only be changed if the KeyMap is empty. Its value can be set conveniently when creating the KeyMap. An error will be reported if an attempt is made to set or clear the attribute when the KeyMap contains any entries.

Type:
Integer.
