isSupported

public boolean isSupported(String sourceMimetype,
                           long sourceSizeInBytes,
                           String targetMimetype,

                           String renditionName)

Description copied from interface: TransformServiceRegistry

Works out if the Transform Server should be able to transform content of a given source mimetype and size into a target mimetype given a list of actual transform option names and values (Strings) plus the data contained in the objects registered with this class.

Specified by:

isSupported in interface TransformServiceRegistry

Parameters:

sourceMimetype - the mimetype of the source content

sourceSizeInBytes - the size in bytes of the source content. Ignored if negative.

targetMimetype - the mimetype of the target

actualOptions - the actual name value pairs available that could be passed to the Transform Service.

renditionName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.

getTransformerName

protected String getTransformerName(String sourceMimetype,
                                    long sourceSizeInBytes,
                                    String targetMimetype,
                                    Map<String,String> actualOptions,
                                    String renditionName)

Works out the name of the transformer (might not map to an actual transformer) that will be used to transform content of a given source mimetype and size into a target mimetype given a list of actual transform option names and values (Strings) plus the data contained in the objects registered with this class.

Parameters:

sourceMimetype - the mimetype of the source content

sourceSizeInBytes - the size in bytes of the source content. Ignored if negative.

targetMimetype - the mimetype of the target

actualOptions - the actual name value pairs available that could be passed to the Transform Service.

renditionName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.

getMaxSize

public long getMaxSize(String sourceMimetype,
                       String targetMimetype,
                       Map<String,String> actualOptions,
                       String renditionName)

Description copied from interface: TransformServiceRegistry

Returns the maximun size (in bytes) of the source content that can be transformed.

Specified by:

getMaxSize in interface TransformServiceRegistry

Parameters:

sourceMimetype - the mimetype of the source content

targetMimetype - the mimetype of the target

actualOptions - the actual name value pairs available that could be passed to the Transform Service.

renditionName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.

Returns:

the maximum size (in bytes) of the source content that can be transformed. If -1 there is no limit, but if 0 the transform is not supported.
