Detailed Description

template<class T, typename Component>
class BinaryListComponent< T, Component >

provides functionality for loading the component data from Binary

Author

Valentin Boettcher

Version

1.0

This class is an abstract Template which requires that the type T is some child of SkyObject and the type Component is some child of ListComponent. The class T must provide a static TYPE property of the type SkyObject::TYPE. This is required because access to the type() method is inconvenient here!

The derived class must provide a void loadFromText() method, which loads the component via addListObject or similar. (This method implements parsing etc, and cannot be abstracted by this class.)

Finally, one has to add this template as a friend class upon deriving it. This is a concession to the already present architecture.

File paths are determent by the means of KSPaths::writableLocation.

Constructor & Destructor Documentation

BinaryListComponent() [1/2]

template<class T , typename Component >

BinaryListComponent< T, Component >::BinaryListComponent	(	Component *	parent,
		QString	basename
	)

BinaryListComponent.

Parameters

parent	a reference to the inheriting child
basename	the base filename for the binary

Sets the file extensions to dat for text and bin for binary.

Definition at line 146 of file binarylistcomponent.h.

template<class T , typename Component >

BinaryListComponent< T, Component >::BinaryListComponent	(	Component *	parent,
		QString	basename,
		QString	txtExt,
		QString	binExt
	)

BinaryListComponent.

Parameters

parent	a reference to the inheriting child
basename	the base filename for the binary
txtExt	text data file extension
binExt	binary data file extension

Definition at line 149 of file binarylistcomponent.h.

Member Function Documentation

clearData()

template<class T , typename Component >

void BinaryListComponent< T, Component >::clearData

protectedvirtual

clearData

Removes the current component data where necessary.

Definition at line 251 of file binarylistcomponent.h.

dropBinary()

template<class T , typename Component >

bool BinaryListComponent< T, Component >::dropBinary

protectedvirtual

dropBinary

Removes the binary file.

Returns

True if operation succeeds

Definition at line 239 of file binarylistcomponent.h.

dropText()

template<class T , typename Component >

bool BinaryListComponent< T, Component >::dropText

protectedvirtual

dropText

Removes the text file.

Returns

True if operation succeeds

Definition at line 245 of file binarylistcomponent.h.

loadData() [1/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::loadData

protectedvirtual

loadData

Calls loadData(false)

Definition at line 156 of file binarylistcomponent.h.

loadData() [2/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::loadData ( bool  dropBinaryFile )

protectedvirtual

loadData

Load the component data from binary (if available) or from text

Parameters

dropBinaryFile

whether to drop the current binary (and to recreate it)

Tip: If you want to reload the data and recreate the binfile, just call loadData(true).

Definition at line 162 of file binarylistcomponent.h.

loadDataFromBinary() [1/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::loadDataFromBinary

protectedvirtual

loadDataFromBinary

Opens the default binfile and calls loadDataFromBinary([FILE])

Definition at line 181 of file binarylistcomponent.h.

loadDataFromBinary() [2/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::loadDataFromBinary ( QFile &  binfile )

protectedvirtual

loadDataFromBinary

Parameters

binfile

the binary file

Loads the component data from the given binary.

Definition at line 188 of file binarylistcomponent.h.

loadDataFromText()

template<class T , typename Component >

virtual void BinaryListComponent< T, Component >::loadDataFromText ( )

protectedpure virtual

loadDataFromText

Load the component data from text.

This method shall be implemented by those who derive this class.

This method should load the component data from text by the use of addListObject or similar.

writeBinary() [1/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::writeBinary

protectedvirtual

writeBinary

Opens the default binfile and calls writeBinary([FILE])

Definition at line 215 of file binarylistcomponent.h.

writeBinary() [2/2]

template<class T , typename Component >

void BinaryListComponent< T, Component >::writeBinary ( QFile &  binfile )

protectedvirtual

writeBinary

Parameters

binfile

Writes the component data to the specified binary. (Destructive)
