Constructor Detail

AbstractDataContainerReader

public AbstractDataContainerReader()

Method Detail

getFormatDescription

public abstract String getFormatDescription()

Returns a string describing the format (used in the file chooser).

Specified by:

getFormatDescription in interface FileFormatHandler

Returns:

a description suitable for displaying in the file chooser

getFormatExtensions

public abstract String[] getFormatExtensions()

Returns the extension(s) of the format.

Specified by:

getFormatExtensions in interface FileFormatHandler

Returns:

the extension (without the dot!)

getDefaultFormatExtension

public String getDefaultFormatExtension()

Returns the default extension of the format.

Specified by:

getDefaultFormatExtension in interface FileFormatHandler

Returns:

the default extension (without the dot!)

getAdditionalInformation

public String getAdditionalInformation()

Returns the additional information.

Specified by:

getAdditionalInformation in interface AdditionalInformationHandler

Returns:

the additional information, null or 0-length string for no information

initialize

protected void initialize()

Initializes the members.

Overrides:

initialize in class AbstractOptionHandler

reset

protected void reset()

Resets the reader (but does not clear the input data!). Derived classes must call this method in set-methods of parameters to assure the invalidation of previously generated data.

Overrides:

reset in class AbstractOptionHandler

defineOptions

public void defineOptions()

Adds options to the internal list of options.

Specified by:

defineOptions in interface OptionHandler

Overrides:

defineOptions in class AbstractOptionHandler

isInputFile

public boolean isInputFile()

Returns whether the input needs to be a file or directory.

Returns:

true if the input needs to be a file, a directory otherwise

setInput

public void setInput(PlaceholderFile value)

Sets the file/directory to read.

Parameters:

value - the file/directory to read

getInput

public PlaceholderFile getInput()

The file/directory to read.

Returns:

the file/directory to read

inputTipText

public String inputTipText()

Returns the tip text for this property.

Returns:

tip text for this property suitable for displaying in the GUI or for listing the options.

setCreateDummyReport

public void setCreateDummyReport(boolean value)

Sets whether to create a dummy report if none present.

Parameters:

value - if true then a dummy report is generated if necessary

getCreateDummyReport

public boolean getCreateDummyReport()

Returns whether to create a dummy report if none present.

Returns:

true if a dummy report is generated if necessary

createDummyReportTipText

public String createDummyReportTipText()

Returns the tip text for this property.

Returns:

tip text for this property suitable for displaying in the GUI or for listing the options.

read

public List<T> read()

Returns the spectrums generated from the file. If necessary, performs the parsing (e.g., if not yet read).

Returns:

the spectrums generated from the file

doRead

protected List<T> doRead()

Performs checks and (always) reads the data.

Returns:

the spectrums generated from the file

checkData

protected void checkData()

The default implementation only checks whether the provided file object is an actual file and whether it exists (if m_InputIsFile = true), or if the file object is a directory and whether it exists.

See Also:

m_InputIsFile

readData

protected abstract void readData()

Performs the actual reading.

postProcessData

protected void postProcessData()

For performing post-processing.

Default implementation adds dummy reports.

See Also:

#createDummyReport()

createDummyReport

protected Report createDummyReport(T cont)

Creates a dummy report.

Default implementation returns null.

Parameters:

cont - the data container the dummy is for

Returns:

the dummy report or null

See Also:

m_CreateDummyReport, postProcessData()

cleanUp

public void cleanUp()

Can be used to free up memory. Default implementation just calls reset(). Derived classes can add additional code.

Specified by:

cleanUp in interface CleanUpHandler

See Also:

reset()

destroy

public void destroy()

Frees up memory in a "destructive" non-reversible way.

Calls cleanUp() and cleans up the options.

Specified by:

destroy in interface Destroyable

Overrides:

destroy in class AbstractOptionHandler

See Also:

AbstractOptionHandler.cleanUpOptions()

compareTo

public int compareTo(Object o)

Only compares the commandlines of the two objects.

Specified by:

compareTo in interface Comparable<T extends DataContainer>

Parameters:

o - the object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

ClassCastException - if the specified object's type prevents it from being compared to this object.

equals
