Class EXIStreamDecoderImpl

java.lang.Object

com.siemens.ct.exi.core.coder.EXIStreamDecoderImpl

All Implemented Interfaces:

EXIStreamDecoder

public class EXIStreamDecoderImpl
extends Object
implements EXIStreamDecoder

An EXI stream is an EXI header followed by an EXI body. The EXI body carries the content of the document, while the EXI header communicates the options used for encoding the EXI body.

Note: In case of multiple EXI documents with EXI Compression mode in one stream or subsequent data in the stream/file one needs to provide the input stream as PushbackInputStream with the size of at least DecodingOptions.PUSHBACK_BUFFER_SIZE. The reason for doing so is that the Java inflater sometimes reads beyond the EXI channel/block and PushbackInputStream allows us to push back this data so that it is not lost.
