Examples with B2CConverter org.apache.tomcat.util.buf.B2CConverter used on opensource projects

Example 1 with B2CConverter

use of org.apache.tomcat.util.buf.B2CConverter in project tomcat by apache.

the class CoyoteAdapter method convertURI.

Example 2 with B2CConverter

use of org.apache.tomcat.util.buf.B2CConverter in project tomcat by apache.
