Method Detail
-
itemAt
T itemAt(int n)
Get the n'th item in the value, counting from 0- Parameters:
n
- the index of the required item, with 0 representing the first item in the sequence- Returns:
- the n'th item if it exists, or null otherwise
-
subsequence
GroundedValue<T> subsequence(int start, int length)
Get a subsequence of the value- Parameters:
start
- the index of the first item to be included in the result, counting from zero. A negative value is taken as zero. If the value is beyond the end of the sequence, an empty sequence is returnedlength
- the number of items to be included in the result. Specify Integer.MAX_VALUE to get the subsequence up to the end of the base sequence. If the value is negative, an empty sequence is returned. If the value goes off the end of the sequence, the result returns items up to the end of the sequence- Returns:
- the required subsequence. If min is
-
getLength
int getLength()
Get the size of the value (the number of items)- Returns:
- the number of items in the sequence
