Member Function Documentation

Byte Okteta::FileByteArrayModel::byte ( Address offset ) const

virtual

locates working range The idea behind is to tell buffer which range will be requested in the following time, so that e.g.

the corresponding pages will be loaded in advance TODO: do we really need this? Where will this lead to real enhancements?

Parameters

Range

Returns: true if successfully, false otherwiseconvenience function, same as above creates an iterator to expects pointer to memory, should be in prepared range it is only expected to be a valid pointer until any further call to this or any modifying function

Parameters

Section

Returns: pointer to convenience function, same as above requests a single byte if the offset is not valid the behaviour is undefined

Parameters

offset offset of the datum requested

Implements Okteta::AbstractByteArrayModel.

Definition at line 48 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::close ( )

Definition at line 57 of file filebytearraymodel.cpp.

Size Okteta::FileByteArrayModel::fill	(	Byte	fillByte,
		Address	offset = `0`,
		Size	fillLength = `-1`
	)

virtual

fills the buffer with the FillChar.

If the buffer is to small it will be extended as much as possible.

Parameters

fillByte	byte to use
offset	position where the filling starts
fillLength	number of bytes to fill. If Length is -1, the buffer is filled till the end.

Returns: number of filled bytes

Implements Okteta::AbstractByteArrayModel.

Definition at line 53 of file filebytearraymodel.cpp.

Size Okteta::FileByteArrayModel::insert	(	Address	offset,
		const Byte *	insertData,
		int	insertLength
	)

virtual

inserts bytes copied from the given source at Position.

The original data beginnung at the position is moved with the buffer enlarged as needed If the buffer is readOnly this is a noop and returns 0.

Parameters

offset
insertData	data source
insertLength	number of bytes to copy

Returns: length of inserted data

Reimplemented from Okteta::AbstractByteArrayModel.

Definition at line 50 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::isModified ( ) const

virtual

Returns: true if the buffer has been modified, false otherwise

Implements Okteta::AbstractByteArrayModel.

Definition at line 42 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::isOpen ( ) const

Definition at line 43 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::isReadOnly ( ) const

virtual

Default returns true.

Returns: true if the buffer can only be read, false if writing is allowed

Reimplemented from Okteta::AbstractByteArrayModel.

Definition at line 41 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::open ( const QString & filename )

Definition at line 56 of file filebytearraymodel.cpp.

Size Okteta::FileByteArrayModel::remove ( const AddressRange & removeRange )

virtual

removes beginning with position as much as possible

Parameters

removeRange

Returns: length of removed data

Reimplemented from Okteta::AbstractByteArrayModel.

Definition at line 51 of file filebytearraymodel.cpp.

Size Okteta::FileByteArrayModel::replace	(	const AddressRange &	removeRange,
		const Byte *	insertData,
		int	insertLength
	)

virtual

replaces as much as possible

Parameters

removeRange
insertData
insertLength

Returns: length of inserted data

Implements Okteta::AbstractByteArrayModel.

Definition at line 52 of file filebytearraymodel.cpp.

void Okteta::FileByteArrayModel::setByte	(	Address	offset,
		Byte	byte
	)

virtual

sets a single byte if the offset is not valid the behaviour is undefined

Parameters

offset	offset of the datum requested
byte	new byte value

Implements Okteta::AbstractByteArrayModel.

Definition at line 47 of file filebytearraymodel.cpp.

void Okteta::FileByteArrayModel::setModified ( bool modified = true )

virtual

sets the modified flag for the buffer

Parameters

modified

Implements Okteta::AbstractByteArrayModel.

Definition at line 46 of file filebytearraymodel.cpp.

void Okteta::FileByteArrayModel::setReadOnly ( bool isReadOnly = true )

virtual

sets the readonly flag for the byte array if this is possible.

Default implementation does not do anything.

Parameters

isReadOnly new state

Reimplemented from Okteta::AbstractByteArrayModel.

Definition at line 45 of file filebytearraymodel.cpp.

Size Okteta::FileByteArrayModel::size ( ) const

virtual

Returns: the size of the data

Implements Okteta::AbstractByteArrayModel.

Definition at line 40 of file filebytearraymodel.cpp.

bool Okteta::FileByteArrayModel::swap	(	Address	firstStart,
		const AddressRange &	secondRange
	)

virtual

moves the second section before the start of the first which is the same as moving the first behind the second.

Parameters

firstStart	position of the data where the section should be moved behind
secondRange	data range to be moved

Returns: if operation was successful, otherwise

Implements Okteta::AbstractByteArrayModel.
