Method Details

_longFromString

public static long _longFromString(String value,
 long defaultValue)

Helper method for parsing strings into numbers. Strips the 0x from strings, if they exist. Also handles the case of 16 character numbers which would be greater than MAX_LONG

Parameters:

value - The string representing the number

defaultValue - The value which will be returned if value is null

Returns:

defaultValue if the value is null or the long value of the given string

_longFromString

public static long _longFromString(String value)

Helper method for parsing strings into numbers. Strips the 0x from strings, if they exist. Also handles the case of 16 character numbers which would be greater than MAX_LONG

Parameters:

value - The string representing the number

Returns:

0 if the value is null or the long value of the given string

_longByResolvingRawKey

public static long _longByResolvingRawKey(String rawText,
 String key)

Looks up the given key in rawText and finds the long that corresponds to it. ie: "... key=number..." Returns 0 if the key is not found.

Parameters:

rawText -

key -

Returns:

nodeToPushAfterStarting

public IParserNode nodeToPushAfterStarting(String uri,
 String localName,
 String qName,
 Attributes attributes)

Description copied from interface: IParserNode

Called when a start tag is parsed. Returns the node to handle this new scope which may be the same instance as the receiver if this same node wants to take responsibility.

Specified by:

nodeToPushAfterStarting in interface IParserNode

Returns:

stringWasParsed

public void stringWasParsed(String string)

Description copied from interface: IParserNode

Called when a literal string is parsed in the XML stream.

Specified by:

stringWasParsed in interface IParserNode

didFinishParsing

public void didFinishParsing()

Description copied from interface: IParserNode

Called when this tag is done being parsed (the start tag and all children have been fully parsed) and it is going to be discarded by the parser.

Specified by:
