Principal getPrincipal(org.wildfly.security.evidence.Evidence evidence)

Get the principal from the given evidence. If this decoder does not understand the given evidence, null is returned.

Parameters:

evidence - the evidence to decode

Returns:

the principal, or null if this decoder does not understand the evidence

apply

default Principal apply(org.wildfly.security.evidence.Evidence evidence)

Specified by:

apply in interface Function<org.wildfly.security.evidence.Evidence, Principal>

aggregate

static EvidenceDecoder aggregate(EvidenceDecoder... decoders)

Create an aggregated evidence decoder. The aggregated decoder will try each evidence decoder until one returns a non-null value. If all the evidence decoders return null, then null will be returned.

Parameters:

decoders - the constituent decoders

Returns:

the aggregated decoder
