OriginalMetadataRequestI

public OriginalMetadataRequestI(PixelsService pixelsService)

Method Detail

getCallContext

public Map<String,String> getCallContext()

Description copied from interface: IRequest

Returns the desired call context for this request. Some request implementations will require "omero.group":"-1" for example and will hard-code that value. Others may permit users to pass in the desired values which will be merged into the static Map as desired.

Specified by:

getCallContext in interface IRequest

Returns:

the call context for this request

init

public void init(Helper helper)

Description copied from interface: IRequest

Method called within the transaction boundaries before any processing occurs. Implementations must properly initialize the "step" field of the Status object by calling Helper.setSteps(int). This count will define how many times the IRequest.step(int) method will be called. The Helper instance passed in contains those resources needed by IRequests to interact with data and should be stored for later use.

Specified by:

init in interface IRequest

Parameters:

helper - the helper for this request

step

public Object step(int step)

Description copied from interface: IRequest

Single uncancellable action which will be performed by this IRequest. The return value can be an ome.model object that is attached to the current thread and transaction. After processing and detachment from the transaction, the object will be passed to IRequest.buildResponse(int, Object) for conversion and storage.

Specified by:

step in interface IRequest

Parameters:

step - the step number

Returns:

an object to be used in building the response

finish

public void finish()
            throws HandleI.Cancel

Description copied from interface: IRequest

Method within the transaction boundaries after all processing has occurred. A thrown HandleI.Cancel will still rollback the current transaction.

Specified by:

finish in interface IRequest

Throws:

HandleI.Cancel - if this request is cancelled

buildResponse

public void buildResponse(int step,
                          Object object)

Description copied from interface: IRequest

Post-transaction chance to map from the return value of IRequest.step(int) to a Response object.

Specified by:

buildResponse in interface IRequest

Parameters:

step - the step number

object - an object to be used in building the response

getResponse

public omero.cmd.Response getResponse()

Description copied from interface: IRequest

Returns the current response value. This method should be protected by synchronization where necessary, and should never raise an exception. It is also guaranteed to be called so that any state cleanup that is necessary can take place here.

Specified by:

getResponse in interface IRequest

Returns:

the response to this request

loadFileset

protected void loadFileset()

Searches for a Fileset attached to this Image, and if present, uses Bio-Formats to parse the metadata into the OriginalMetadataResponse instance. If no Fileset is present, then there may be a FileAnnotation present which has a static version of the metadata.

loadFileAnnotation

protected void loadFileAnnotation()

Only called if loadFileset() finds no Fileset. If any FileAnnotation instances with the appropriate namespace and name are found, the first one is taken and parsed into the OriginalMetadataResponse.

firstIdOrNull

protected omero.RLong firstIdOrNull(String query)

Use IQuery.projection(String, Parameters) to load the first long which matches the given query. This means that the first return value in the select statement should likely be the id of an object.

wrap

protected Map<String,omero.RType> wrap(Hashtable<String,Object> table)

Use IceMapper to convert from Object instances in the given Hashtable to RType instances. This may throw an exception on unknown types.

parseOriginalMetadataTxt

protected void parseOriginalMetadataTxt(File file)

Read the given INI-style file and populate the maps with the properties from the corresponding sections.

Parameters:

file - the file to read

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
