A read-only enumerator of pointers to CERT_CONTEXT structures.

Inheritance

The IOpcCertificateEnumerator interface inherits from the IUnknown interface. IOpcCertificateEnumerator also has these types of members:

Methods

The IOpcCertificateEnumerator interface has these methods.


IOpcCertificateEnumerator::Clone Creates a copy of the current IOpcCertificateEnumerator interface pointer and all its descendants.
IOpcCertificateEnumerator::GetCurrent Gets the CERT_CONTEXT structure at the current position of the enumerator.
IOpcCertificateEnumerator::MoveNext Moves the current position of the enumerator to the next CERT_CONTEXT structure.
IOpcCertificateEnumerator::MovePrevious Moves the current position of the enumerator to the previous CERT_CONTEXT structure.

Remarks

When an enumerator is created, the current position precedes the first pointer of the enumerator. To set the current position to the first pointer, call the MoveNext method after the enumerator is created.

Changes to the set will invalidate the enumerator and all subsequent calls to it will fail.

To get an IOpcCertificateEnumerator interface pointer, call the IOpcCertificateSet::GetEnumerator or IOpcDigitalSignature::GetCertificateEnumerator method.
