Method Detail

newCompressionInputStream

public static InputStream newCompressionInputStream(InputStream content)

This factory method creates an InputStream that compresses its content while reading in the same way that the Saperion backend expects "PKZIP" compressed data. The compression is actually "DEFLATE" without any header or checksum.

Parameters:

content - an input stream with the content to compress

Returns:

an input stream that compresses as expected by the native part

newDecompressionInputStream

public static InputStream newDecompressionInputStream(InputStream compressed)

This factory creates an InputStream that decompresses data compressed with the Saperion backend "PKZIP" compression on the fly. The compression is actually "DEFLATE" without any header or checksum.

Parameters:

compressed - an input stream with the compressed content

Returns:

an input stream decompressing the content

newDecompressionFactory

public static InputStreamFilterFactory newDecompressionFactory()

This factory creates a new InputStreamFilterFactory that delegates to newDecompressionInputStream(InputStream).

Returns:

a new InputStreamFilterFactory that delegates to newDecompressionInputStream(InputStream)
