Interface CertPathChecker
- All Known Implementing Classes:
- PKIXCertPathChecker,- PKIXRevocationChecker
public interface CertPathChecker
Performs one or more checks on each Certificate of a
 CertPath.
 
A CertPathChecker implementation is typically created to extend
 a certification path validation algorithm. For example, an implementation
 may check for and process a critical private extension of each certificate
 in a certification path.

Method SummaryModifier and TypeMethodDescriptionvoidcheck(Certificate cert) Performs the check(s) on the specified certificate using its internal state.voidinit(boolean forward) Initializes the internal state of thisCertPathChecker.booleanIndicates if forward checking is supported.
- 
Method Details- 
initInitializes the internal state of thisCertPathChecker.The forwardflag specifies the order that certificates will be passed to thecheckmethod (forward or reverse).- Parameters:
- forward- the order that certificates are presented to the- checkmethod. If- true, certificates are presented from target to trust anchor (forward); if- false, from trust anchor to target (reverse).
- Throws:
- CertPathValidatorException- if this- CertPathCheckeris unable to check certificates in the specified order
 
- 
isForwardCheckingSupportedboolean isForwardCheckingSupported()Indicates if forward checking is supported. Forward checking refers to the ability of theCertPathCheckerto perform its checks when certificates are presented to thecheckmethod in the forward direction (from target to trust anchor).- Returns:
- trueif forward checking is supported,- falseotherwise
 
- 
checkPerforms the check(s) on the specified certificate using its internal state. The certificates are presented in the order specified by theinitmethod.- Parameters:
- cert- the- Certificateto be checked
- Throws:
- CertPathValidatorException- if the specified certificate does not pass the check
