 #### Constants
 
-_CONTENT\_TYPE_: The mime type of the content that is output by the handler
-
-_CONTINUE_: The stack loop continues onto the next handler after handling; this is the default behavior
-
-_BREAK_: The stack loop breaks after the handler finishes, causing any further down in the stack to not run
-
-_EXIT_: The stack loop exits after running all handlers
-
-_OUTPUT_: The handler will output

 #### Properties (Protected)
 
 Properties which begin with an underscore all are options. They can be set either through the constructor or via `setHandler` by name, removing the underscore at the beginning. All handlers inherit these options.
 
-_outputBuffer_: This is where the output arrays representing the handled throwables are stored until they are dispatched.
-
-_\_backtraceArgFrameLimit_: The number of frames by which there can be arguments output with them. Defaults to _5_.
-
-_\_charset_: The character set of the output; only used if headers weren't sent before an error occurred. Defaults to _"UTF\_8"_.
-
-_\_forceBreak_: When set this will force the stack loop to break after the handler has run. Defaults to _false_.
-
-_\_forceExit_: When set this will force an exit after all handlers have been run. Defaults to _false_.
-
-_\_forceOutputNow_: When set this will force output of the handler immediately. Defaults to _false_.
-
-_\_httpCode_: The HTTP code to be sent; possible values are 200, 400-599. Defaults to _500_.
-
-_\_outputBacktrace_: When true will output a stack trace. Defaults to _false_.
-
-_\_outputPrevious_: When true will output previous throwables. Defaults to _true_.
-
-_\_outputTime_: When true will output times to the output. Defaults to _true_.
-
-_\_outputToStderr_: When the SAPI is cli output errors to stderr. Defaults to _true_.

-_\_silent_: When true the handler won't output anything. Defaults to _false_.
