isWritable	back to summary
public default boolean isWritable() Indicate whether the contents of this resource can be written via `getOutputStream()`. Will be `true` for typical resource descriptors; note that actual content writing may still fail when attempted. However, a value of `false` is a definitive indication that the resource content cannot be modified. See Also `getOutputStream()`, `isReadable()`

public default boolean isWritable()

Indicate whether the contents of this resource can be written via getOutputStream().

Will be true for typical resource descriptors; note that actual content writing may still fail when attempted. However, a value of false is a definitive indication that the resource content cannot be modified.

writableChannel back to summary

writableChannel	back to summary
public default WritableByteChannel writableChannel() throws IOException Return a `WritableByteChannel`. It is expected that each call creates a fresh channel. The default implementation returns `Channels#newChannel(OutputStream)` with the result of `getOutputStream()`. Returns:WritableByteChannel the byte channel for the underlying resource (must not be `null`) Exceptions IOException: if the content channel could not be opened FileNotFoundException: if the underlying resource doesn't exist Since 5.0 See Also `getOutputStream()`

public default WritableByteChannel writableChannel() throws IOException

Returns:WritableByteChannel

the byte channel for the underlying resource (must not be null)

Exceptions

IOException:: if the content channel could not be opened
FileNotFoundException:: if the underlying resource doesn't exist
