VaultWrite Event

Fires to write data to a callback mode vault.

Syntax

public class DefaultCbvaultEventListener implements CbvaultEventListener {
  ...
  public void vaultWrite(CbvaultVaultWriteEvent e) {}
  ...
}

public class CbvaultVaultWriteEvent {
  public long vaultHandle;
  public long offset;
  public ByteBuffer buffer;
  public int count;
  public int resultCode;
}

Remarks

This event fires when the class needs to write data to the callback mode vault specified by VaultHandle.

This event only needs to be handled if the CallbackMode property is enabled; please refer to the Callback Mode topic for more information. To handle this event properly, applications must write Count bytes of data from Buffer to the vault specified by VaultHandle, starting at the specified Offset in the vault.

Count is always a multiple of the vault's PageSize. If, for any reason, an application cannot write exactly Count bytes of data to the vault, it must return an appropriate error code via ResultCode.

Please refer to the Buffer Parameters topic for more information on how to work with memory buffer event parameters.

The VaultHandle parameter contains an application-defined handle to an open callback mode vault, as returned by the application in an earlier VaultOpen event.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
