Method Detail

printlnWithHeader

public void printlnWithHeader(java.lang.String message)

Description copied from interface: org.apache.derby.iapi.services.stream.HeaderPrintWriter

Puts out some setup info for the current write and the write(s) that will be put out next. It ends with a \n\r.

All other writes to the stream use the PrintStream interface.

---

getPrintWriter

public java.io.PrintWriter getPrintWriter()

Description copied from interface: org.apache.derby.iapi.services.stream.HeaderPrintWriter

Gets a PrintWriter object for writing to this HeaderPrintWriter. Users may use the HeaderPrintWriter to access methods not included in this interface or to invoke methods or constructors which require a PrintWriter. Interleaving calls to a printWriter and its associated HeaderPrintWriter is not supported.

Specified by:

getPrintWriter in interface org.apache.derby.iapi.services.stream.HeaderPrintWriter

---

getName

public java.lang.String getName()

Description copied from interface: org.apache.derby.iapi.services.stream.HeaderPrintWriter
