Method Detail

deleteNames

void deleteNames(java.util.List<java.lang.String> names,
                 boolean force)
          throws EngineException

Delete a number of names. If a connection is not yet established, this method will request a connection.

Parameters:

names - Names to be deleted.

force - Set to true to forcably delete the names even if in use.

Throws:

EngineException

deleteNamesFromFile

void deleteNamesFromFile(java.util.List<java.lang.String> filenames,
                         boolean force)
                  throws EngineException

Delete a number of names from a file or stdin. If a connection is not yet established, this method will request a connection.

Parameters:

filenames - Names of files to read Names from. A file name "-" is taken to be stdin.

force - Set to true to forcably delete the names even if in use.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

deleteNamesFromFile

void deleteNamesFromFile(java.util.List<java.lang.String> filenames,
                         boolean force,
                         boolean utf8)
                  throws EngineException

Delete a number of names from a file or stdin. If a connection is not yet established, this method will request a connection.

Parameters:

filenames - Names of files to read Names from. A file name "-" is taken to be stdin.

force - Set to true to forcably delete the names even if in use.

utf8 - If true, the specified files will be read as UTF-8; otherwise they will be read using the system default encoding unless they begin with a unicode Byte Order Mark (BOM) character.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

deleteAll

void deleteAll()
        throws EngineException

Deletes everything from the engine.

Throws:

EngineException

deleteName

void deleteName(java.lang.String name,
                boolean force)
         throws EngineException

Delete a name from the engine. If a connection is not yet established, this method will request a connection.

Parameters:

name - The name to be deleted.

force - Set to true to forcably delete the name even if in use.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

killNames

void killNames(java.util.List<java.lang.String> names)
        throws EngineException

Kill a number of names. Note that this will kill running monitors in such as way as to break the fault tolerance scheme. If a connection is not yet established, this method will request a connection.

Parameters:

names - Names to be deleted.

Throws:

EngineException

killNamesFromFile

void killNamesFromFile(java.util.List<java.lang.String> filenames)
                throws EngineException

Kill a number of names from a file or stdin. Note that this will kill running monitors in such as way as to break the fault tolerance scheme. If a connection is not yet established, this method will request a connection.

Parameters:

filenames - Names of files to read Names from. A file name "-" is taken to be stdin.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

killNamesFromFile

void killNamesFromFile(java.util.List<java.lang.String> filenames,
                       boolean utf8)
                throws EngineException

Kill a number of names from a file or stdin. Note that this will kill running monitors in such as way as to break the fault tolerance scheme. If a connection is not yet established, this method will request a connection.

Parameters:

filenames - Names of files to read Names from. A file name "-" is taken to be stdin.

utf8 - If true, the specified files will be read as UTF-8; otherwise they will be read using the system default encoding unless they begin with a unicode Byte Order Mark (BOM) character.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

killName

void killName(java.lang.String name)
       throws EngineException

Kill a name from the engine. Note that this will kill running monitors in such as way as to break the fault tolerance scheme. If a connection is not yet established, this method will request a connection.

Parameters:

name - The name to be deleted.

Throws:

EngineException - Thrown if any exceptions occur in the Client SDK.

setCancelDeleteFileRead

void setCancelDeleteFileRead(boolean newCancelFileReadValue)

Setter for the cancelFileRead property for the Delete / Kill operations. The purpose of the cancelFileRead property is to provide a mechanism to cleanly terminate the processing of events from file, when the deleteNamesFromFile() or killNamesFromFile() method is in progress. When cancelFileRead is set to true, the Name deleting loop will terminate at the next iteration.

Parameters:

newCancelFileReadValue - New value for the cancelFileRead property.
