Initializes using the given string

Method Detail

skipSpace

public static int skipSpace(java.lang.String sourceString,
                            int startPos,
                            char[] spaceChars)

Returns the position of the next word in the given string according to the given start position.

Parameters:

startPos - the minimum position.

spaceChars - the characters to skip.

Returns:

the position of the next occurrence of a character which is not contained in spaceChars.

extract

public ExtractedString extract(int startPos,
                               int endPos)

Initializes the extraction.

Parameters:

startPos - the start position from where to extract.

endPos - the end position until where to extract.

Returns:

this instance.

extract

public ExtractedString extract(int startPos,
                               char[] terminalChars,
                               int charMinCheckIndex,
                               char openBracket,
                               char closeBracket)

Initializes the extraction.

Parameters:

startPos - the start position from where to start the extraction.

terminalChars - the characters at where to end the extraction. Once one of the characters appear, the extraction is stopped.

charMinCheckIndex - the offset for the terminalChars array. Characters with index below this argument will not be checked.

openBracket - the opening bracket. The extraction never stops between an opening and a closing bracket.

closeBracket - the closing bracket. The extraction never stops between an opening and a closing bracket.

Returns:

this instance.

extract

public ExtractedString extract(int startPos,
                               char terminalChar,
                               char openBracket,
                               char closeBracket)

Initializes the extraction.

Parameters:

startPos - the start position from where to start the extraction.

terminalChar - the character at where to end the extraction.

openBracket - the opening bracket. The extraction never stops between an opening and a closing bracket.

closeBracket - the closing bracket. The extraction never stops between an opening and a closing bracket.

Returns:

this instance.

extract

public ExtractedString extract(int startPos,

                               int charMinCheckIndex)

Initializes the extraction.

Parameters:

startPos - the start position of the extraction.

terminalChars - the characters at which to stop the extraction. That is, the extraction stops, if one of the given characters occurs, beginning at charMinCheckIndex.

charMinCheckIndex - an offset for the terminalChars array. All indices below charMinCheckIndex will be ignored.

Returns:

this instance.
