the class EclipseHandlerUtil method methodExists.

/**
	 * Checks if there is a method with the provided name. In case of multiple methods (overloading), only
	 * the first method decides if EXISTS_BY_USER or EXISTS_BY_LOMBOK is returned.
	 * 
	 * @param methodName the method name to check for.
	 * @param node Any node that represents the Type (TypeDeclaration) to look in, or any child node thereof.
	 * @param caseSensitive If the search should be case sensitive.
	 * @param params The number of parameters the method should have; varargs count as 0-*. Set to -1 to find any method with the appropriate name regardless of parameter count.
