  CertPathChecker
  
  
  
| java.security.cert.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.

Public methods
check
public abstract void check (Certificate cert)
Performs the check(s) on the specified certificate using its internal
 state. The certificates are presented in the order specified by the
 init method.
| Parameters | |
|---|---|
| cert | Certificate: theCertificateto be checked | 
| Throws | |
|---|---|
| CertPathValidatorException | if the specified certificate does not pass the check | 
init
public abstract void init (boolean forward)
Initializes the internal state of this CertPathChecker.
 
The forward flag specifies the order that certificates will
 be passed to the check method (forward or reverse).
| Parameters | |
|---|---|
| forward | boolean: the order that certificates are presented to thecheckmethod. Iftrue, certificates are
        presented from target to trust anchor (forward); iffalse, from trust anchor to target (reverse). | 
| Throws | |
|---|---|
| CertPathValidatorException | if this CertPathCheckeris
         unable to check certificates in the specified order | 
isForwardCheckingSupported
public abstract boolean isForwardCheckingSupported ()
Indicates if forward checking is supported. Forward checking refers
 to the ability of the CertPathChecker to perform its checks
 when certificates are presented to the check method in the
 forward direction (from target to trust anchor).
| Returns | |
|---|---|
| boolean | trueif forward checking is supported,falseotherwise |
