 javax.swing.text.html.parser.Asn1Dtd
| Asn1Dtd | | class Asn1Dtd (Code) | | It implements ASN.1 codification tools for
javax.swing.text.html.parser.DTD. Given an DTD,
its values are codified in ASN.1 according to the following rule:
BDTD ::= SEQUENCE {
Name UTF8String,
Entity SET OF HTMLEntity,
Element SET OF HTMLElement
}
The class can be used to obtain a byte array representing the codification of
a DTD, as well as a DTD from a byte array
(previously obtained codifying a DTD). In fact, it serves as a
wrapper for the codification and the DTD itself.

| Constructor Summary | |
| public | Asn1Dtd(byte[] encoded)
Constructs a new instance of a Asn1Dtd class from a byte
array. | | public | Asn1Dtd(DTD dtd)
Constructs a new instance of an Asn1Dtd class from a
DTD. |
| Method Summary | |
| public DTD | getDTD(DTD refDTD)
Returns the DTD obtained from the decodification of an
ASN.1 codified byte array.
If the Asn1Dtd was created giving a DTD, a
reference to the same DTD is obtained. | | public byte[] | getEncoded()
Returns the representation of a DTD in ASN.1 codification.
If the Asn1Dtd object was created with a DTD,
then the DTD is codified and returned as a byte array. | | static ASN1Type | getInstance()
It returns an ASN1Type value that contains the ASN.1
codification rules for a DTD with its encoder and decoder. |
| Asn1Dtd | | public Asn1Dtd(byte[] encoded)(Code) | | Constructs a new instance of a Asn1Dtd class from a byte
array. The byte array received as argument can be later decodified into a
DTD.
Parameters:
encoded - A byte array containing the codified information of aDTD. |
| Asn1Dtd | | public Asn1Dtd(DTD dtd)(Code) | | Constructs a new instance of an Asn1Dtd class from a
DTD. The DTD received as argument can be
then codified into a byte array.
The value received as argument should not be null. If so, a
NullPointerException is thrown.
Parameters:
dtd - The DTD to be codified. |
| getDTD | | public DTD getDTD(DTD refDTD) throws IOException(Code) | | Returns the DTD obtained from the decodification of an
ASN.1 codified byte array.
If the Asn1Dtd was created giving a DTD, a
reference to the same DTD is obtained. Otherwise, the byte
array given at construction time is decodificated into a new
DTD object.
If at construction time a DTD was given, the sameDTD is returned. If at construction time a bytearray was given, a DTD constructed with theinformation stored in that byte array is returned.
throws:
IOException - If the decodification process could not be carried outproperly. |
| getEncoded | | public byte[] getEncoded()(Code) | | Returns the representation of a DTD in ASN.1 codification.
If the Asn1Dtd object was created with a DTD,
then the DTD is codified and returned as a byte array. On
the other hand, if the instance was created using a byte array, then no
codification process is made.
If at construction time a DTD was given, itsrepresentation in ASN.1 codification. If at construction time abyte array was given, a copy of the same array is returned. |
| getInstance | | static ASN1Type getInstance()(Code) | | It returns an ASN1Type value that contains the ASN.1
codification rules for a DTD with its encoder and decoder.
The value that defines an ASN.1 DTD representationwith its encoder/decoder. |
