Constructor Detail

SequentialInStreamImpl

public SequentialInStreamImpl(java.io.InputStream inputStream)

Create instance of SequentialInStreamImpl based on InputStream

Parameters:

inputStream - input stream to use

Method Detail

read

public int read(byte[] data)
         throws SevenZipException

Reads at least 1 and maximum data.length from the in-stream. If data.length == 0 0 should be returned. If data.length != 0, then return value 0 indicates end-of-stream (EOF). This means no more bytes can be read from the stream.
This function is allowed to read less than number of remaining bytes in stream and less then data.length. You must call read() function in loop, if you need exact amount of data.

Specified by:

read in interface ISequentialInStream

Parameters:

data - buffer to get read data

Returns:

amount of bytes written in the data array. 0 - represents end of stream.

Throws:

SevenZipException - in error case. If this method ends with an exception, the current operation will be reported to 7-Zip as failed. There are no guarantee, that there are no further call back methods will be called. The first thrown exception will be saved and thrown late on from the first called 7-Zip-JBinding main method, such as ISevenZipInArchive.extract() or SevenZip.openInArchive().

getInputStream

public java.io.InputStream getInputStream()

Get underlaying input stream

Returns:

input stream
