Method Detail

getOutputStream

public FinishableOutputStream getOutputStream(FinishableOutputStream out,
                                              ArrayCache arrayCache)

Description copied from class: FilterOptions

Gets a raw (no XZ headers) encoder output stream using these options and the given ArrayCache. Raw streams are an advanced feature. In most cases you want to store the compressed data in the .xz container format instead of using a raw stream. To use this filter in a .xz file, pass this object to XZOutputStream.

Specified by:

getOutputStream in class FilterOptions

getInputStream

public java.io.InputStream getInputStream(java.io.InputStream in,
                                          ArrayCache arrayCache)

Description copied from class: FilterOptions

Gets a raw (no XZ headers) decoder input stream using these options and the given ArrayCache.

Specified by:

getInputStream in class FilterOptions

setStartOffset

public void setStartOffset(int startOffset)
                    throws UnsupportedOptionsException

Sets the start offset for the address conversions. Normally this is useless so you shouldn't use this function. The default value is 0.

Throws:

UnsupportedOptionsException

getStartOffset

public int getStartOffset()

Gets the start offset.

getEncoderMemoryUsage

public int getEncoderMemoryUsage()

Description copied from class: FilterOptions

Gets how much memory the encoder will need with these options.

Specified by:

getEncoderMemoryUsage in class FilterOptions

getDecoderMemoryUsage

public int getDecoderMemoryUsage()

Description copied from class: FilterOptions

Gets how much memory the decoder will need to decompress the data that was encoded with these options.

Specified by:

getDecoderMemoryUsage in class FilterOptions

clone

public java.lang.Object clone()
