loadVOTable
void loadVOTable(ExtApp app, java.io.InputStream in)
Allow an "external" application to send new data via an InputStream in VOTable format. The reference to this "external" application has to passed in order to eventually calls back the "external" application, or to be called again by the "external" application concerning the VOTable objects that it had sent before (see showVOTableObject() and selectVOTableObject() methods below) For this calls or callbacks, the "external" application has to create a new VOTable column giving an unique identifier for each object that it has sent. This column has to be described by the following VOTable FIELD tag: <FIELD name="_OID" type="hidden">. It is strongly recommended to add an unambigus prefix to avoid conflicts with the assignations done by the "external" application and its own assignations. The unicity has to be maintained during all the session. It means that successive VOTables must have difference unique identifiers.- Parameters:
app
- "external" application compliante with ExtApp java interfacein
- VOTable stream
-
setVisible
void setVisible(boolean flag)
Allow an "external" application to show or hide this application
-
execCommand
java.lang.String execCommand(java.lang.String cmd)
Allow an "external" application to control by script this application- Parameters:
cmd
- script command depending to this application- Returns:
- error or messages, can be null
-
showVOTableObject
void showVOTableObject(java.lang.String[] oid)
Call or Callback asking the other application to SHOW objects found in a VOTable previous transmission via loadVOTable() method. The action "SHOW" is a choice of the other application (for example a blink)- Parameters:
oid
- list of identifiers found in VOTables (see comment of the loadVOTable() method.
-
selectVOTableObject
void selectVOTableObject(java.lang.String[] oid)
Call or Callback asking the other application to SELECT objects found in a VOTable previous transmission via loadVOTable() method. The action "SELECT" is a choice of the other application (for example select objects by showing the corresponding measurements, it can be the same thing that the "SHOW" action - see showVOTableObject() method.)- Parameters:
oid
- list of identifiers found in VOTables (see comment of the loadVOTable() method.
