Note:The properties of theint,boolean,byte,long,double,decimal,short, andfloattypes are the same as the properties of the Java primitive data types of the same name. Service-defined data types Some services require data as input and provide output data that are represented by a data type tha...
As a simple example, if the <delimiter-string> specified a comma, and the <escape-string> specified a backslash, then an input of "a,b' would be split into two fields "a" and "b", but an input of "a\,b" would result in a single field "a,b"....
