public interface GroundedValue extends ValueRepresentation
Method Summary | |
---|---|
Item | itemAt(int n)
Get the n'th item in the value, counting from 0 |
GroundedValue | subsequence(int start, int length)
Get a subsequence of the value |
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
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 returned length 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
