Method Detail

copy

void copy(byte value)
          throws java.io.IOException

This method is used to copy a single byte to the encode buffer or stream. It first converts the byte to a hex character representation and then copies it to the output buffer.

Parameters:

value - The byte value to copy

Throws:

java.io.IOException - If I/O error occurs.

copy

void copy(byte[] value)
          throws java.io.IOException,
                 Asn1Exception

This method copies multiple bytes to the encode buffer or stream. It is assumed the byte are already formatted into a valid XML encoding type (for example, UTF-8).

Parameters:

value - Array of bytes to copy to the encode buffer

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

copy

void copy(byte[] value,
          int off,
          int len)
          throws java.io.IOException,
                 Asn1Exception

This method copies multiple bytes to the encode buffer or stream. It is assumed the byte are already formatted into a valid XML encoding type (for example, UTF-8).

Parameters:

value - Array of bytes to copy to the encode buffer

off - Starting offset in array

len - The length to be encoded

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

copy

void copy(java.lang.String value)
          throws java.io.IOException,
                 Asn1Exception

This method copies a character string to the encode buffer or stream.

Parameters:

value - The string value to copy

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

incrLevel

void incrLevel()

This method increments the element nesting level counter.

decrLevel

void decrLevel()

This method decrements the element nesting level counter.

encodeData

void encodeData(java.lang.String value)
                throws java.io.IOException,
                       Asn1Exception

This method encodes XML string data

Parameters:

value - String value to encode

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

encodeBinStrValue

void encodeBinStrValue(byte[] bits,
                       int nbits)
                       throws java.io.IOException,
                              Asn1Exception

This method encodes XML binary string data

Parameters:

bits - Bit string to encode

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

encodeHexStrValue

void encodeHexStrValue(byte[] data)
                       throws java.io.IOException,
                              Asn1Exception

This method encodes XML hexadecimal string data

Parameters:

data - Data to encode

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

encodeEndDocument

void encodeEndDocument()
                       throws java.io.IOException,
                              Asn1Exception

This method encodes standard trailor information at the end of the XML document.

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.

encodeStartDocument

This methods indents by adding a new-line followed by whitespace corresponding to the current nesting level to the encode buffer.

Throws:

java.io.IOException - If I/O error occurs.

Asn1Exception - Thrown, if operation is failed.
