close	back to summary
public void close() throws IOException Implements java.io.Closeable.close. Doc from java.io.Closeable.close. Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect. As noted in `AutoCloseable#close()`, cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the `Closeable` as closed, prior to throwing the `IOException`.

public void close() throws IOException

Implements java.io.Closeable.close.

Doc from java.io.Closeable.close.

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable#close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.

createSubView	back to summary
public RandomAccessRead createSubView(long length) Overrides org.apache.fontbox.ttf.TTFDataStream.createSubView. Doc from org.apache.fontbox.ttf.TTFDataStream.createSubView. Creates a view from current position to `pos + length`. It can be faster than `read(length)` if you only need a few bytes. `SubView.close()` should never close `TTFDataStream.this`, only itself. Returns:RandomAccessRead A view or null (caller can use `read` instead). Please close() the result Annotations @Override
