KeyInfoBuilder in OpenSAML 3

[Stephen.CTR.Chappell at faa.gov]

Well that makes sense I think. So, more like this then?

XMLObjectBuilder<?> kiBuilder = builderFactory.getBuilder(KeyInfo.DEFAULT_ELEMENT_NAME);
ki = (KeyInfo) kiBuilder.buildObject(KeyInfo.DEFAULT_ELEMENT_NAME);


But I wouldn't have thought that based on the example Brent referenced ...

// Get the assertion builder based on the assertion element name
SAMLObjectBuilder<Assertion> builder = (SAMLObjectBuilder<Assertion>) builderFactory.getBuilder(Assertion.DEFAULT_ELEMENT_NAME);
 
// Create the assertion
Assertion assertion = builder.buildObject();

Normally you don't cast the Builder itself, just the result. If you have a reference to an impl class, you're basically depending on code that's free to change at any time.
