sun.security.x509.BasicConstraintsExtension
| BasicConstraintsExtension | | public class BasicConstraintsExtension extends Extension implements CertAttrSet(Code) | | This class represents the Basic Constraints Extension.
The basic constraints extension identifies whether the subject of the
certificate is a CA and how deep a certification path may exist
through that CA.
The ASN.1 syntax for this extension is:
BasicConstraints ::= SEQUENCE {
cA BOOLEAN DEFAULT FALSE,
pathLenConstraint INTEGER (0..MAX) OPTIONAL
}

| BasicConstraintsExtension | | public BasicConstraintsExtension(boolean ca, int len) throws IOException(Code) | | Default constructor for this object. The extension is marked
critical if the ca flag is true, false otherwise.
Parameters:
ca - true, if the subject of the Certificate is a CA.
Parameters:
len - specifies the depth of the certification path. |
| BasicConstraintsExtension | | public BasicConstraintsExtension(Boolean critical, boolean ca, int len) throws IOException(Code) | | Constructor for this object with specified criticality.
Parameters:
critical - true, if the extension should be marked critical
Parameters:
ca - true, if the subject of the Certificate is a CA.
Parameters:
len - specifies the depth of the certification path. |
| BasicConstraintsExtension | | public BasicConstraintsExtension(Boolean critical, Object value) throws IOException(Code) | | Create the extension from the passed DER encoded value of the same.
Parameters:
extension - the DER encoded value of the extension.
exception:
IOException - on error. |
| decode | | public void decode(InputStream in) throws IOException(Code) | | Decode the extension from the InputStream.
Parameters:
in - the InputStream to unmarshal the contents from.
exception:
IOException - on decoding or validity errors. |
| encode | | public void encode(OutputStream out) throws IOException(Code) | | Encode this extension value to the output stream.
Parameters:
out - the DerOutputStream to encode the extension to. |
