Method Details

withStopOnEmptyBlock

public LZ4BlockInputStream.Builder withStopOnEmptyBlock(boolean stopOnEmptyBlock)

Registers value of stopOnEmptyBlock to be used by the builder

Parameters:

stopOnEmptyBlock - whether read is stopped on an empty block

Returns:

current builder instance

withDecompressor

public LZ4BlockInputStream.Builder withDecompressor(LZ4FastDecompressor fastDecompressor)

Registers LZ4FastDecompressor to be used by the builder as a decompressor. Overrides one set by withDecompressor(LZ4SafeDecompressor)

Parameters:

fastDecompressor - the LZ4FastDecompressor instance to use

Returns:

current builder instance

withDecompressor

public LZ4BlockInputStream.Builder withDecompressor(LZ4SafeDecompressor safeDecompressor)

Registers LZ4SafeDecompressor to be used by the builder as a decompressor. Overrides one set by withDecompressor(LZ4FastDecompressor)

Parameters:

safeDecompressor - the LZ4SafeDecompressor instance to use.

Returns:

current builder instance

withChecksum

public LZ4BlockInputStream.Builder withChecksum(Checksum checksum)

Registers Checksum to be used by the builder

Note: Since checksum objects are stateful, if you set one explicitly here, the builder can only be used once.

Parameters:

checksum - the Checksum instance to use, must be equivalent to the instance which has been used to write the stream

Returns:

current builder instance

build

public LZ4BlockInputStream build(InputStream in)

Creates a new LZ4 input stream to read from the specified InputStream with specified parameters

Parameters:

in - the InputStream to poll

Returns:

new instance of LZ4BlockInputStream using parameters set in the builder and provided InputStream
