Class ConditionalInputStream

java.lang.Object
  java.io.InputStream
      org.freehep.util.io.ConditionalInputStream

public class ConditionalInputStream

extends InputStream

The ConditionalInputStream reads a stream and filters certain parts depending of properties and statements in the input.

The following statements, all start with the @-sign, are allowed:

• @ifdef property, reads everything up to the next @statement if the property is defined.
• @ifndef property, reads everything up to the next @statement if the property is not defined.
• @else, corresponding else statement
• @endif, corresponging endif statement

The @-sign itself must be escaped by a backslash, if used in the text followed by any of the keywords described above and no action should be taken.

IMPORTANT: inherits from InputStream rather than FilterInputStream so that the correct read(byte[], int, int) method is used.
