Method Detail

canValidate

public boolean canValidate(Object data)

Description copied from interface: ValidateHandler

Determine whether this handler can validate the supplied data. Typically, the data will be a MAGETABInvestigation, MAGETABArrayDesign, IDF, SDRF, ADF or nodes from the SDRF or ADF graphs.

This data should be passed to the handler prior to writing to determine whether this handler can handle it

Specified by:

canValidate in interface ValidateHandler<IDF>

Parameters:

data - the data that will be validated

Returns:

true if this handler can handle this tag, false otherwise

validate

public void validate(IDF data)
              throws ValidateException

Invoke this validate handler. This will validate the supplied data assigned to this handler.

This abstract implementation delegates the responsibility for setting the correct fields to concrete implementations via validateData(uk.ac.ebi.arrayexpress2.magetab.datamodel.IDF). This method itself governs the update of progress tracking and status information.

Specified by:

validate in interface ValidateHandler<IDF>

Parameters:

data - the data object to be validated

Throws:

ValidateException - if the handler failed to validate data from it's source

canValidateData

protected abstract boolean canValidateData(IDF idf)

Performs specific checks on the IDF to determine if this handler can validate it. This is different from canValidate(Object) in that it is typed to the IDF and not any object - canValidate(Object) handles type checking at the abstract level.

Parameters:

idf - the IDF to check

validateData

protected abstract void validateData(IDF data)
                              throws ValidateException

Performs the unit of work to validate the data. Override this method in implementations, so that you don't need to implement status updating and checking code.

This method is passed the IDF to validate from.

Throws:

ValidateException - if there was an error validating the data
