Method Detail

isCA

public boolean isCA()

Returns the cA.

Returns:

ASN1Boolean

getPathLenConstraints

public int getPathLenConstraints()

Returns the pathLenConstraints.

Returns:

ASN1Integer

setCA

public void setCA(boolean cA)

Sets the cA.

Parameters:

cA - The cA to set

setPathLenConstraints

decode

public void decode(Decoder dec)
            throws ASN1Exception,
                   IOException

Description copied from class: ASN1AbstractCollection

Reads this collection from the given decoder. This type is initialised with the decoded data. The components of the decoded collection must match the components of this collection. If they do then the components are also initialised with the decoded values. Otherwise an exception is thrown.

Specified by:

decode in interface ASN1Type

Overrides:

decode in class ASN1AbstractCollection

Throws:

ASN1Exception

IOException

toString

public String toString(String offset)

Description copied from class: X509Extension

Returns a human-readable String representation of this extension with an offset String.

Overrides:

toString in class X509Extension

Parameters:

offset - String that will be put before each line of output
