Method Detail

computeClosingMarker

public java.lang.String computeClosingMarker(char[] input,
                                             int startPoint)

Computes the closing marker for a block comment based on the opening marker. This is needed because block comments can nest, so their opening and closing markers necessarily can be variable length. Specifically, the basic open/close marker pair are: [% and %]. But the number of % can be incremented to any amount, so long as the closing marker matches. So, [%%%% and %%%%] are a legal pair.

Parameters:

input - the text containing the opening marker

startPoint - where the opening marker begins

Returns:

a string containing the closing marker, or null if an error occurred.
