Constructor Detail

Asn1DerEncodeBuffer

public Asn1DerEncodeBuffer()

This constructor creates a DER encode buffer object with the default size increment. Whenever the buffer becomes full, the buffer will be expanded by the sizeIncrement size.

Asn1DerEncodeBuffer

public Asn1DerEncodeBuffer(int sizeIncrement)

This constructor creates a DER encode buffer object with the given size increment. Whenever the buffer becomes full, the buffer will be expanded by the sizeIncrement size. This size should be large enough to prevent resizing in normal operation.

Parameters:

sizeIncrement - The initial size in bytes of an encode buffer. If the buffer becomes full, it will be expanded by the amount.

Method Detail

isBER

public boolean isBER()

This method is used for testing encode rules type.
