public IntegerListFSM(int count)

Method Detail

pushDown

public boolean pushDown(char c)

Description copied from class: StringParserFSM

Parse the next character. This isn't terribly Unicode safe, now, is it?

Specified by:

pushDown in class StringParserFSM

Parameters:

c - the character to push onto the stack

Returns:

true if the character was added to the stack

reset

public void reset()

Description copied from class: StringParserFSM

Reset to the start state.

Specified by:

reset in class StringParserFSM

toString

public java.lang.String toString()

Description copied from class: StringParserFSM

Gets the current parsed characters. It should be a valid string of the language the FSM represents, or an empty string. It is up to the implementor to decide what to do with a partial string.

Specified by:

toString in class StringParserFSM

Returns:

the current parsed characters

getValidString

public java.lang.String getValidString()

Description copied from class: StringParserFSM

Gets a valid version from the current state. For example, a floating point with toString as "12e" would return the valid part "12", or a bounding box parsed as "12 13 4" might return "12 13 4 0" or "".

Overrides:

getValidString in class StringParserFSM

Returns:

Default is to return the value of 'toString' method
