Method Details

createFilter

static ErrorLogFactory createFilter(Predicate<ErrorLogArgProvider> predicate)

Helper method to create an error log factory that selectively enables error logs.

Any exception (represented as an ErrorLogArgProvider) that doesn't match the provided Predicate is excluded from the error log. Other exceptions are logged using the default format.

Parameters:

predicate - the filter that returns true if the exception should be logged, false otherwise

Returns:

an ErrorLogFactory to be used in HttpServer.errorLog(boolean, ErrorLogFactory)

createFilter

static ErrorLogFactory createFilter(Predicate<ErrorLogArgProvider> predicate,
 ErrorLogFactory formatFunction)

Helper method to create an error log factory that selectively enables error logs and customizes the format to apply.

Any exception (represented as an ErrorLogArgProvider) that doesn't match the provided Predicate is excluded from the error log. Other exceptions are logged using the provided formatting Function. Create an ErrorLog instance by defining both the String format and a vararg of the relevant arguments, extracted from the ErrorLogArgProvider.

Parameters:

predicate - the filter that returns true if the exception should be logged, false otherwise

formatFunction - the ErrorLogFactory that creates ErrorLog instances, encapsulating the format and the extraction of relevant arguments

Returns:

an ErrorLogFactory to be used in HttpServer.errorLog(boolean, ErrorLogFactory)
