Field Detail

FIELDS

public static final List<String> FIELDS

Length

public WinDef.DWORD Length

Size of this event record, in bytes. Note that this value is stored at both ends of the entry to ease moving forward or backward through the log. The length includes any pad bytes inserted at the end of the record for DWORD alignment.

Reserved

public WinDef.DWORD Reserved

Reserved.

RecordNumber

public WinDef.DWORD RecordNumber

Record number of the record. This value can be used with the EVENTLOG_SEEK_READ flag in the ReadEventLog function to begin reading at a specified record.

TimeGenerated

public WinDef.DWORD TimeGenerated

Time at which this entry was submitted. This time is measured in the number of seconds elapsed since 00:00:00 January 1, 1970, Universal Coordinated Time.

TimeWritten

public WinDef.DWORD TimeWritten

Time at which this entry was received by the service to be written to the log. This time is measured in the number of seconds elapsed since 00:00:00 January 1, 1970, Universal Coordinated Time.

EventID

public WinDef.DWORD EventID

Event identifier. The value is specific to the event source for the event, and is used with source name to locate a description string in the message file for the event source.

EventType

public WinDef.WORD EventType

Type of event.

NumStrings

public WinDef.WORD NumStrings

Number of strings present in the log (at the position indicated by StringOffset). These strings are merged into the message before it is displayed to the user.

EventCategory

public WinDef.WORD EventCategory

Category for this event. The meaning of this value depends on the event source.

ReservedFlags

public WinDef.WORD ReservedFlags

Reserved.

ClosingRecordNumber

public WinDef.DWORD ClosingRecordNumber

Reserved.

StringOffset

public WinDef.DWORD StringOffset

Offset of the description strings within this event log record.

UserSidLength

public WinDef.DWORD UserSidLength

Size of the UserSid member, in bytes. This value can be zero if no security identifier was provided.

UserSidOffset

public WinDef.DWORD UserSidOffset

Offset of the security identifier (SID) within this event log record. To obtain the user name for this SID, use the LookupAccountSid function.

DataLength

public WinDef.DWORD DataLength

Size of the event-specific data (at the position indicated by DataOffset), in bytes.

DataOffset

public WinDef.DWORD DataOffset

Offset of the event-specific information within this event log record, in bytes. This information could be something specific (a disk driver might log the number of retries, for example), followed by binary information specific to the event being logged and to the source that generated the entry.

Method Detail

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
