Method Detail

nextItem

public Expression nextItem()

Returns the next AST node in the list. This method may be called repeatedly to iterate through the list, or intermixed with calls to previous() to go back and forth. (Note that alternating calls to next() and previous() will return the same element repeatedly.)

Returns:

The next AST node in the list.

previousItem

public Expression previousItem()

Returns the previous element in the list. This method may be called repeatedly to iterate through the list backwards, or intermixed with calls to next to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)

Returns:

The previous AST node in the list.
