Constructor Detail

MetadataExtension

public MetadataExtension(Object obj)
                  throws IOException
Construct a MetadataExtension using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to MetadataExtension.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
MetadataExtension o = (MetadataExtension)obj; // will not work

MetadataExtension o = new MetadataExtension(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:
IOException - if there are interop problems MetadataExtension theMetadataExtension = (MetadataExtension) obj;

setSynchronizationOption

public void setSynchronizationOption(int option)

                                     AutomationException
When the Catalog creates and updates metadata automatically.

Remarks

The SynchronizationOption property is set for all items in ArcGIS, not individual documents. Synchronization cannot be disabled for individual documents in ArcGIS 10. By default the property is set to esriSyncAccessed, where metadata is always created and always updated. This property only determines if synchronization occurs when the metadata is viewed. It does not affect if metadata is updated programmatically or if synchronization occurs in connection with other operations.

The SynchronizationOption property can also be controlled through the user interface. A check box is available in the ArcGIS applicationís Options dialog box that determines if metadata will be updated automatically when you view metadata. When the box is checked synchronization will always occur, and if metadata has not already been created it will be created. The SynchronizationOption property is set to esriSyncAccessed.

When unchecked, synchronization will never occur when you view the itemís metadata. The SynchronizationOption property is set to esriSyncNever. Other actions will update the metadata automatically even when this box is unchecked including using geoprocessing tools on the item, importing metadata, and so on.

Specified by:
setSynchronizationOption in interface IMetadataHelper
Parameters:
option - A com.esri.arcgis.catalog.esriSynchronizationOption constant (in)

Description

This SynchronizationOption property allows for control of how metadata is created and updated automatically using ArcCatalog.

Remarks

The SynchronizationOption property is set for all items in ArcGIS, not individual documents. Synchronization cannot be disabled for individual documents in ArcGIS 10. By default the property is set to esriSyncAccessed, where metadata is always created and always updated. This property only determines if synchronization occurs when the metadata is viewed.

Supported Platforms

Windows

Specified by:
setSynchronizationInterval in interface IMetadataHelper
Parameters:
interval - The interval (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getSynchronizationInterval

public int getSynchronizationInterval()
                               throws IOException,
                                      AutomationException
The interval in seconds from the last update which must elapse before the Catalog will again update the metadata.

Description

The SynchronizationInterval property allows metadata updates and creation to occur at regular intervals.

The value of the SynchronizationInterval property is measured in seconds.

Remarks

Depending how Updating metadata and Creating metadata (available from the SynchronizationOption property) are set up, by default, metadata is updated or created every time the selected item is viewed through the Metadata Tab (GxDocumentationView).

By default the SynchronizationInterval is 0 seconds, thus creating or updating metadata every time an item is viewed in the Metadata Tab. As long as the current time is 1 second past the values in the SyncDate & SyncTime, metadata will be updated.

Rather than continually updating or creating metadata, the SynchronizationInterval property allows the user to control when and how regularly metadata is updated or created. For instance if multiple people were accessing a feature class, one editing features and the other viewing metadata, with the default setting, the changes in the metadata would reflect those new edits in the feature class the first time the metadata was accessed through the Metadata Tab after the edits were committed. Changing the SynchronizationInterval property can postpone when changes are viewed.

This property was originally put in place to help deal with system load so that metadata is not having to be constantly created. But since the system load is rarely affected by the creation of metadata, it is a good idea to keep the defaults and always have the most accurate metadata.
