Terminator

The Terminator property specifies whether or not the delimiter should appear for the last node of current level. For example, it determines whether data should look like "a,b,|" or "a,b|" assuming "," (comma) is the current level delimiter and "|" (pipe) is the parent level delimiter.

The delimiter that terminates the last child of the level in question is referred to as the terminator.

Table 12 Terminator Mode Options

Option	Rule
never	Specifies that the delimiter is not allowed to be a terminator in input and will not be emitted as terminator in output.
allow	Specifies that the delimiter is allowed to be a terminator in input but will not be emitted as terminator in output.
cheer	Specifies that the delimiter is allowed to be a terminator in input and will be emitted as terminator in output.
force	Specifies that the delimiter must appear as a terminator in input and will also be emitted as terminator in output.

Consider the tree structure shown in the following figure, where the node a has a caret (^) as its delimiter, and its child nodes b and c have asterisks (*) as their delimiters.
