Constructor Summary

Asn1DerEncodeBuffer()
This constructor creates a DER encode buffer object with the default size.

Constructor Detail

Asn1DerEncodeBuffer

public Asn1DerEncodeBuffer()

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

Asn1DerEncodeBuffer

public Asn1DerEncodeBuffer(int size)

This constructor creates a DER encode buffer object with the given initial size. Whenever the buffer becomes full, the buffer will be expanded. For best performance, this size should be large enough to prevent resizing in normal operation.

Parameters:

size - The initial size in bytes of an encode buffer.

Method Detail

isBER

public boolean isBER()

This method returns true when the underlying buffer is a BER buffer. This returns false for the DER implementation.

Overrides:

isBER in class Asn1BerEncodeBuffer

Returns:

False.
