PrimitiveTLV

public PrimitiveTLV(Tag newtag,
                    byte[] newvalue)

Create a primitive TLV object with tag and value

Parameters:

newtag - Tag as object

newvalue - Byte array containing value

PrimitiveTLV

public PrimitiveTLV(int newTagValue,
                    byte[] newvalue)
             throws TLVEncodingException

Create a primitive TLV object with tag given as integer value

Parameters:

newTagValue - Tag as integer value

newvalue - Byte array containing value

Throws:

TLVEncodingException

PrimitiveTLV

public PrimitiveTLV(byte[] buffer,
                    int offset)
             throws TLVEncodingException

Create a primitive TLV object from binary data in buffer at given offset

Parameters:

buffer - Buffer containing TLV object

offset - Offset in buffer

Throws:

TLVEncodingException

PrimitiveTLV

public PrimitiveTLV(byte[] buffer)
             throws TLVEncodingException

Create a primitive TLV object or structure from binary

Parameters:

buffer - Binary data containing TLV structure

Throws:

TLVEncodingException

PrimitiveTLV

public PrimitiveTLV(ParseBuffer pb)
             throws TLVEncodingException

Create a primitive TLV object from binary in parse buffer

Parameters:

pb - Binary data containing TLV structure

Throws:

TLVEncodingException

PrimitiveTLV

public PrimitiveTLV(TLV tlv)
             throws TLVEncodingException

Copy constructor Initialize with existing PrimitiveTLV object. Does not perform a deep copy. The tag and value 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 - PrimitiveTLV

Throws:

java.lang.UnsupportedOperationException

TLVEncodingException
