PPrint

public PPrint(Configuration configuration)

Instantiates a new PPrint.

Parameters:

configuration - configuration

Method Detail

return one less than the number of bytes used by the UTF-8 byte sequence. The Unicode char is returned in ch.

Parameters:

str - points to the UTF-8 byte sequence

start - starting offset in str

ch - initialized to 1st byte, passed as an array to allow modification

Returns:

one less that the number of bytes used by UTF-8 char

putUTF8

                          int c)

store char c as UTF-8 encoded byte stream.

Parameters:

buf -

start -

c -

countSlides

public int countSlides(Node node)

Split parse tree by h2 elements and output to separate files. Counts number of h2 children (if any) belonging to node.

Parameters:
