Method Detail

encodeAsHexChar

public final void encodeAsHexChar(byte value)
                           throws java.io.IOException

Encode the given byte to hexadecimal chars.

Parameters:

value - The byte to be encoded.

Throws:

java.io.IOException - for I/O exception

encodeAsHexChars

public final void encodeAsHexChars(byte[] data,
                                   int len)
                            throws java.io.IOException

Encode the given bytes to hexadecimal chars.

Parameters:

data - The bytes to be encoded.

len - The number of bytes to encode from data. len <= data.length

Throws:

java.io.IOException - for I/O exception

encodeCharStrOctStr

public final void encodeCharStrOctStr(java.lang.String value)
                               throws java.io.IOException

Encode the given character string to a JSON string as if the character string were an octet string. This is used for encoding ASN.1 types TeletexString, T61String, VideotexString, GraphicString, and GeneralString. This will encode the enclosing double quotes.

Parameters:

value - The String to encode.

Throws:

java.io.IOException

encodeString

public final void encodeString(java.lang.String value)
                        throws java.io.IOException

Encode the given Java string as a JSON string. This will encode the enclosing double quotes, and will escape the string's characters as needed.

Parameters:

value - The String to encode.

Throws:

java.io.IOException
