Constructor Detail

### NexusBlockParser.Abstract

    public NexusBlockParser.Abstract(NexusBlockListener blockListener)

Method Detail

### getBlockListener

    public NexusBlockListener getBlockListener()

  Description copied from interface: `NexusBlockParser`
  Obtain the listener for this parser.

  Specified by:
    `getBlockListener` in interface `NexusBlockParser`
  Returns:
    the listener.

### startBlock

    public void startBlock(String blockName)

  Description copied from interface: `NexusBlockParser`
  Notifies the parser that a new block is starting.

  Specified by:
    `startBlock` in interface `NexusBlockParser`
  Parameters:
    `blockName` - the name of the block.

### resetStatus

    protected abstract void resetStatus()

  This function is called when the parser is reset before starting a new block.

### getBlockName

    protected String getBlockName()

### endBlock

    public void endBlock()

  Description copied from interface: `NexusBlockParser`
  Notifies the parser that a block is ending.

  Specified by:
    `endBlock` in interface `NexusBlockParser`

### beginComment

    public void beginComment()

  Description copied from interface: `NexusBlockParser`
  Opening a comment tag.

  Specified by:
    `beginComment` in interface `NexusBlockParser`

### endComment

    public void endComment()

  Description copied from interface: `NexusBlockParser`
  Closing a comment tag.

  Specified by:
    `endComment` in interface `NexusBlockParser`

### endTokenGroup

    public void endTokenGroup()

  Description copied from interface: `NexusBlockParser`
  Closing a line (semi-colon encountered). This indicates that anything received after it is on the next logical line of the block.

  Specified by:
    `endTokenGroup` in interface `NexusBlockParser`

### commentText

    public void commentText(String comment)
                     throws ParseException

  Description copied from interface: `NexusBlockParser`
  Receiving free text inside a comment tag.

  Specified by:
    `commentText` in interface `NexusBlockParser`
  Parameters:
    `comment` - the text of the comment.
  Throws:
    `ParseException`

### parseToken

    public abstract void parseToken(String token)
                             throws ParseException

  Description copied from interface: `NexusBlockParser`
  Notifies the parser of the next token. Comment tokens will already have been parsed out and sent separately to the text() method of the listener. Quoted strings will have been parsed and underscores converted. What this token contains is the full string, after removal of quotes if necessary. The token will never be only whitespace.

  Specified by:
    `parseToken` in interface `NexusBlockParser`
  Parameters:
    `token` - the token to parse.
  Throws:
    `ParseException` - if the token is unparseable.

### wantsBracketsAndBraces

    public boolean wantsBracketsAndBraces()

  Description copied from interface: `NexusBlockParser`
  Does the listener want to know about brackets and braces as separate tokens?

  Specified by:
    `wantsBracketsAndBraces` in interface `NexusBlockParser`
  Returns:
    `true` if it does.
