the file to write to.

m_OutputIsFile

protected boolean m_OutputIsFile

indicates whether the output has to be a file (= default) or directory.

Constructor Detail

AbstractDataContainerWriter

public AbstractDataContainerWriter()

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(s) (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

reset

protected void reset()

Resets the writer (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

isOutputFile

public boolean isOutputFile()

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

Returns:

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

setOutput

public void setOutput(PlaceholderFile value)

Sets the file/directory to write to.

Parameters:

value - the file/directory to write to

getOutput

public PlaceholderFile getOutput()

The file/directory to write to.

Returns:

the file/directory to write to

outputTipText

public String outputTipText()

Returns the tip text for this property.

Returns:

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

canWriteMultiple

public abstract boolean canWriteMultiple()

Returns whether writing of multiple containers is supported.

Returns:

true if multiple containers are supported

write

public boolean write(T data)

Performs checks and writes the data.

Parameters:

data - the data to write

Returns:

true if successfully written

See Also:

write(List)

write

public boolean write(List<T> data)

Performs checks and writes the data.

Parameters:

data - the data to write

Returns:

true if successfully written

checkData

protected void checkData(List<T> data)

The default implementation only checks whether the provided file is an actual file and whether it exists (if m_OutputIsFile is TRUE). Otherwise the directory has to exist.

Parameters:

data - the data to write

writeData

protected abstract boolean writeData(List<T> data)

Performs the actual writing.

Parameters:

data - the data to write

Returns:

true if successfully written

cleanUp

public void cleanUp()

Can be used to free up memory. Default implementation just calls reset() and sets the spectrum to null. 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)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

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

public boolean equals(Object o)

Returns whether the two objects are the same.

Only compares the commandlines of the two objects.

Overrides:

equals in class Object

Parameters:
