Called by spring after bean is initialised.

onBootstrap

protected void onBootstrap(org.springframework.context.ApplicationEvent event)

Specified by:

onBootstrap in class org.springframework.extensions.surf.util.AbstractLifecycleBean

onShutdown

protected void onShutdown(org.springframework.context.ApplicationEvent event)

Specified by:

onShutdown in class org.springframework.extensions.surf.util.AbstractLifecycleBean

getProperty

public java.lang.String getProperty(java.lang.String name)

Returns a transformer property value.

Specified by:

getProperty in interface TransformerConfig

Parameters:

name - of the property.

Returns:

a transformer property or null if not set.

getProperties

public java.lang.String getProperties(boolean changesOnly)

Description copied from interface: TransformerConfig

Returns a sorted set of all transformer properties, their values and includes comments about the properties.

Specified by:

getProperties in interface TransformerConfig

Parameters:

changesOnly - only custom values will be included.

Returns:

a multi-line String which is never {code null}.

setProperties

public int setProperties(java.lang.String propertyNamesAndValues)

Sets a transformer property values. These will be stored in the database but on an MBean reset is cleared.

Specified by:

setProperties in interface TransformerConfig

Parameters:

propertyNamesAndValues - new line separated name and values

Returns:

the number of properties set.

removeProperties

public int removeProperties(java.lang.String propertyNames)

Description copied from interface: TransformerConfig

Removes transformer properties.

Specified by:

removeProperties in interface TransformerConfig

Parameters:

propertyNames - new line separated names. Any values will be ignored.

Returns:

the number of properties removed.

getStatistics

public TransformerStatistics getStatistics(ContentTransformer transformer,
                                  java.lang.String sourceMimetype,
                                  java.lang.String targetMimetype,
                                  boolean createNew)

Returns and creates if needed the TransformerStatistics object for the combination of transformer, sourceMimetype and targetMimetype. When transformer is null this is the system wide summary object for a combination of sourceMimetype and targetMimetype. When both sourceMimetype and targetMimetype are null this is the transformer's summary object. When all three parameters are null this is the system wide summary for all transformers.

Specified by:

getStatistics in interface TransformerConfig

Parameters:

transformer - the transformer for which data is being recorded.

sourceMimetype - the source mimetype.

targetMimetype - the source mimetype.

createNew - indicates if a new object should be created if it does not exist.

Returns:

the requested TransformerStatistics.

getLimits

public TransformationOptionLimits getLimits(ContentTransformer transformer,
                                   java.lang.String sourceMimetype,
                                   java.lang.String targetMimetype,
                                   java.lang.String use)

Returns the limits defined for the combination of transformer, sourceMimetype and targetMimetype. When the transformer is null, this is a default value. When both sourceMimetype and targetMimetype are null this is a default for the specified transformer.

Specified by:

getLimits in interface TransformerConfig

use - to which the limits will be put. For example "index", "webpreview", "doclib", "syncRule", "aysncRule". null is the default.

Returns:

the combined (takes into account defaults from higher levels) limits for the combination.

isSupportedTransformation

public boolean isSupportedTransformation(ContentTransformer transformer,
                                java.lang.String sourceMimetype,
                                java.lang.String targetMimetype,
                                TransformationOptions options)

Returns true if the supplied mimetype transformation pair is allowed by the list of supported and unsupported transformations.

Specified by:

isSupportedTransformation in interface TransformerConfig

options - not currently used

getPriority

public int getPriority(ContentTransformer transformer,
              java.lang.String sourceMimetype,
              java.lang.String targetMimetype)

Returns the priority of the specified transformer for the the combination of source and target mimetype.

Specified by:

getPriority in interface TransformerConfig

Returns:

the priority. To support the historical concept of EXPLICIT transformers, all such transformers are given a PRIORITY_EXPLICIT (50). By default transformers have a default of 100.

getThresholdCount

public int getThresholdCount(ContentTransformer transformer,
                    java.lang.String sourceMimetype,
                    java.lang.String targetMimetype)

Returns the threshold of the transformer. It is only after this number of transformation attempts that the average time is used.

Specified by:

getThresholdCount in interface TransformerConfig

Returns:

the threshold.
