Display or return formatted version of message body data

Syntax

Description

show([body](#bu9bka%5F-1-body)) displays the entireData property of a message body if Data is a scalar string or character vector. For other types, the method displays a message indicating the length of the data in bytes, if known. If length is unknown, then the value displayed is the length of the data if body were sent in a request message.

The show method formatsData when possible. For example, the method puts separators between parts of a multipart message and separately converts each part to a string. IfData is a string or character vector, then the string andshow methods return the same value.

Use this method for diagnostics or debugging.

example

show([body](#bu9bka%5F-1-body),[maxlength](#bu9bka%5F-1-maxlength)) displays the first maxlength characters of Data. If Data is longer than maxlength characters, then the method displays the total length of the data.

example

str = show(___) returns a string containing the information to be displayed, and can include any of the input arguments in previous syntaxes.
