  +--org.bouncycastle.openpgp.PGPPublicKeyRingCollection

All Implemented Interfaces:

org.bouncycastle.util.Iterable

Direct Known Subclasses:

BcPGPPublicKeyRingCollection, JcaPGPPublicKeyRingCollection

public class PGPPublicKeyRingCollection

extends java.lang.Object

implements org.bouncycastle.util.Iterable

Often a PGP key ring file is made up of a succession of master/sub-key key rings. If you want to read an entire public key file in one hit this is the class for you.

PGPPublicKeyRingCollection

public PGPPublicKeyRingCollection(java.util.Collection collection)

Method Detail

size

public int size()

Return the number of rings in this collection.

Returns:

size of the collection

getKeyRings

public java.util.Iterator getKeyRings()

return the public key rings making up this collection.

getKeyRings

public java.util.Iterator getKeyRings(java.lang.String userID)

Return an iterator of the key rings associated with the passed in userID.

Parameters:

userID - the user ID to be matched.

Returns:

an iterator (possibly empty) of key rings which matched.

getKeyRings

public java.util.Iterator getKeyRings(java.lang.String userID,
                                      boolean matchPartial)

Return an iterator of the key rings associated with the passed in userID.

Parameters:

userID - the user ID to be matched.

matchPartial - if true userID need only be a substring of an actual ID string to match.

Returns:

an iterator (possibly empty) of key rings which matched.

getKeyRings
