org.alfresco.repo.content.transform.ContentTransformerHelper

org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker

All Implemented Interfaces:

ContentTransformerWorker, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean

@Deprecated
@AlfrescoPublicApi
public class RuntimeExecutableContentTransformerWorker
extends ContentTransformerHelper
implements ContentTransformerWorker, org.springframework.beans.factory.InitializingBean

Deprecated.

The transformations code is being moved out of the codebase and replaced by the new async RenditionService2 or other external libraries.

This configurable wrapper is able to execute any command line transformation that accepts an input and an output file on the command line.

The following parameters are use:

• target - full path to the source file
• source - full path to the target file

Provided that the command executed ultimately transforms the source file and leaves the result in the target file, the transformation should be successful.

NOTE: It is only the contents of the files that can be transformed. Any attempt to modify the source or target file metadata will, at best, have no effect, but may ultimately lead to the transformation failing. This is because the files provided are both temporary files that reside in a location outside the system's content store.

This transformer requires the setting of the explicitTransformations property.

1.1

Method Detail

toString

public String toString()

Deprecated.

Overrides:

toString in class ContentTransformerHelper

setCheckCommand

public void setCheckCommand(RuntimeExec checkCommand)

Deprecated.

Set the runtime executer that will be called as part of the initialisation to determine if the transformer is able to function. This is optional, but allows the transformer registry to detect and avoid using this instance if it is not working.

The command will be considered to have failed if the

Parameters:

checkCommand - the initialisation check command

setTransformCommand

public void setTransformCommand(RuntimeExec transformCommand)

Deprecated.

Set the runtime executer that will called to perform the actual transformation.

Parameters:

transformCommand - the runtime transform command

setErrorCodes

public void setErrorCodes(String errCodesStr)

Deprecated.

A comma or space separated list of values that, if returned by the executed command, indicate an error value. This defaults to "1, 2".

Parameters:

errCodesStr - String

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

Executes the check command, if present. Any errors will result in this component being rendered unusable within the transformer registry, but may still be called directly.

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

isTransformable

public boolean isTransformable(String sourceMimetype,
                               String targetMimetype,
                               TransformationOptions options)

Deprecated.

If the initialization failed, then it returns 0.0. Otherwise the explicit transformations are checked for the reliability.

Specified by:

isTransformable in interface ContentTransformerWorker

Returns:

Returns 1.0 if initialization succeeded, otherwise 0.0.

getComments

public String getComments(boolean available)

Deprecated.

Description copied from class: ContentTransformerHelper

Overridden to supply a comment or String of commented out transformation properties that specify any (hard coded or implied) supported transformations. Used when providing a list of properties to an administrators who may be setting other transformation properties, via JMX. Consider overriding if {link AbstractContentTransformerLimits.isTransformableMimetype(String, String, TransformationOptions) or ContentTransformerWorker.isTransformable(String, String, TransformationOptions) have been overridden. See ContentTransformerHelper.getCommentsOnlySupports(List, List, boolean) which may be used to help construct a comment.

Specified by:

getComments in interface ContentTransformerWorker

Overrides:

getComments in class ContentTransformerHelper

Parameters:

available - indicates if the transformer has been registered and is available to be selected. false indicates that the transformer is only available as a component of a complex transformer.

Returns:

one line per property. The simple transformer name is returned by default as a comment.

ContentTransformer.getComments(boolean)

isAvailable

public boolean isAvailable()

Deprecated.

Signals whether this transformer is available.

Specified by:

isAvailable in interface ContentTransformerWorker

Returns:

true, if is available

getVersionString

public String getVersionString()

Deprecated.

Gets the version string captured from the check command.

Specified by:

getVersionString in interface ContentTransformerWorker

Returns:

the version string
