the class ParameterGuesser method parameterProposals.

/**
	 * Returns the matches for the type and name argument, ordered by match quality.
	 *
	 * @param expectedType - the qualified type of the parameter we are trying to match
	 * @param paramName - the name of the parameter (used to find similarly named matches)
	 * @param pos the position
	 * @param suggestions the suggestions or <code>null</code>
	 * @param fillBestGuess <code>true</code> if the best guess should be filled in
	 * @param isLastParameter <code>true</code> iff this proposal is for the last parameter of a method
	 * @return returns the name of the best match, or <code>null</code> if no match found
	 * @throws org.eclipse.jdt.core.JavaModelException if it fails
