ByteArrayDataSink

Kotlin |Java

@UnstableApi
public final class ByteArrayDataSink implements DataSink

A DataSink for writing to a byte array.

Summary

Public constructors
`ByteArrayDataSink()`

Public methods
`void`	`close()` Closes the sink.
`@Nullable byte[]`	`getData()` Returns the data written to the sink since the last call to `open`, or null if `open` has never been called.
`void`	`open(DataSpec dataSpec)` Opens the sink to consume the specified data.
`void`	`write(byte[] buffer, int offset, int length)` Consumes the provided data.

public ByteArrayDataSink()

public void close()

Closes the sink.

Note: This method must be called even if the corresponding call to open threw an IOException. See open for more details.

Throws
`java.io.IOException`	If an error occurs closing the sink.

public @Nullable byte[] getData()

Returns the data written to the sink since the last call to open, or null if open has never been called.

public void open(DataSpec dataSpec)

Opens the sink to consume the specified data.

Note: If an IOException is thrown, callers must still call close to ensure that any partial effects of the invocation are cleaned up.

Parameters
`DataSpec dataSpec`	Defines the data to be consumed.

Throws
`java.io.IOException`	If an error occurs opening the sink.

public void write(byte[] buffer, int offset, int length)

Consumes the provided data.

Parameters
`byte[] buffer`	The buffer from which data should be consumed.
`int offset`	The offset of the data to consume in `buffer`.
`int length`	The length of the data to consume, in bytes.

Throws
`java.io.IOException`	If an error occurs writing to the sink.
