writeTo	back to summary
public void writeTo(ByteStreamWriter.ByteStreamTarget target) throws IOException Implements org.postgresql.util.ByteStreamWriter.writeTo. Doc from org.postgresql.util.ByteStreamWriter.writeTo. Write the data to the provided `OutputStream`. Should not write more than `getLength()` bytes. If attempted, the provided stream will throw an `java.io.IOException`. Parameters target:ByteStreamWriter.ByteStreamTarget the stream to write the data to Annotations @Override Exceptions IOException: if the underlying stream throws or there is some other error.

public void writeTo(ByteStreamWriter.ByteStreamTarget target) throws IOException

Implements org.postgresql.util.ByteStreamWriter.writeTo.

Doc from org.postgresql.util.ByteStreamWriter.writeTo.

Write the data to the provided OutputStream.

Should not write more than getLength() bytes. If attempted, the provided stream will throw an java.io.IOException.

Parameters

target:ByteStreamWriter.ByteStreamTarget: the stream to write the data to
