Method Detail

getNextToken

public String getNextToken(String delimiter)

Starting from the current reading position, extract the next token terminated by delimiter. Advances the read pointer past the delimiter.

Parameters:

delimiter - a regular expression that describes the next delimiter

Throws:

IllegalStateException - if the current string value doesn't contain the delimiter sequence

getNextToken

public String getNextToken(int numCharacters)

Starting from the current reading position, extract the next numCharacters characters. Advances the read pointer past the returned output.

getNextBytes

public byte[] getNextBytes(int numBytes)

Starting from the current reading position, extract the next numBytes bytes. Advances the read pointer past the returned output. Caution: this will destroy successive characters when the read pointer is stopped at a non-character boundary.

skipDelimiter

public void skipDelimiter(String delimiter)

peek

public String peek(int numChars)

getCurrentOffset

public int getCurrentOffset()

Returns the current read pointer position (in number of characters).
