Constructor Detail

ConstructedTLV

public ConstructedTLV(Tag newtag)

Create empty constructed tlv object with given Tag object

Parameters:

newtag - Tag for constructed TLV object

ConstructedTLV

public ConstructedTLV(int tagValue)
               throws TLVEncodingException

Create empty constructed tlv object and given Tag value

Parameters:

tagValue - Tag value for constructed TLV object

Throws:

TLVEncodingException

ConstructedTLV

public ConstructedTLV(ParseBuffer pb)
               throws TLVEncodingException

Create a constructed tlv object from binary data in ParseBuffer

Parameters:

pb - Byte array containing TLV structure

Throws:

TLVEncodingException

ConstructedTLV

public ConstructedTLV(byte[] buffer)
               throws TLVEncodingException

Create constructed TLV object from byte array

Parameters:

buffer - Byte array containing data object

Throws:

TLVEncodingException

ConstructedTLV

public ConstructedTLV(TLV tlv)
               throws java.lang.UnsupportedOperationException

Copy constructor Initialize with existing ConstructedTLV object. Does not perform a deep copy. The tag and list of contained objects are reassigned. Caution: If applied to a TLV object embedded in a complex structure remember to update the reference to this object in the parent node.

Parameters:

tlv - ConstructedTLV

Throws:

java.lang.UnsupportedOperationException
