Tokenizer.Token |
get()
Gets the next token from a tokenizer, ignoring whitespace and comments. |
Tokenizer.Token |
get(boolean wantWhitespace,
boolean wantComment)
Gets the next token from a tokenizer. |
InetAddress |
getAddress(int family)
Gets the next token from a tokenizer and converts it to an IP Address. |
byte[] |
getBase32String(base32 b32)
Gets the next token from a tokenizer and decodes it as base32. |
byte[] |
getBase64()
Gets the remaining string tokens until an EOL/EOF is seen, concatenates them together, and converts the base64 encoded data to a byte array. |
byte[] |
getBase64(boolean required)
Gets the remaining string tokens until an EOL/EOF is seen, concatenates them together, and converts the base64 encoded data to a byte array. |
void |
getEOL()
Gets the next token from a tokenizer, which must be an EOL or EOF. |
byte[] |
getHex()
Gets the remaining string tokens until an EOL/EOF is seen, concatenates them together, and converts the hex encoded data to a byte array. |
byte[] |
getHex(boolean required)
Gets the remaining string tokens until an EOL/EOF is seen, concatenates them together, and converts the hex encoded data to a byte array. |
byte[] |
getHexString()
Gets the next token from a tokenizer and decodes it as hex. |
String |
getIdentifier()
Gets the next token from a tokenizer, ensures it is an unquoted string, and converts it to a string. |
long |
getLong()
Gets the next token from a tokenizer and converts it to a long. |
Name |
getName(Name origin)
Gets the next token from a tokenizer and converts it to a name. |
String |
getString()
Gets the next token from a tokenizer and converts it to a string. |
long |
getTTL()
Gets the next token from a tokenizer and parses it as a TTL. |
long |
getTTLLike()
Gets the next token from a tokenizer and parses it as if it were a TTL. |
int |
getUInt16()
Gets the next token from a tokenizer and converts it to an unsigned 16 bit integer. |
long |
getUInt32()
Gets the next token from a tokenizer and converts it to an unsigned 32 bit integer. |
int |
getUInt8()
Gets the next token from a tokenizer and converts it to an unsigned 8 bit integer. |
void |
unget()
Returns a token to the stream, so that it will be returned by the next call to get(). |
