Method Details

openInputStream

public InputStream openInputStream()
                            throws IOException

Specified by:

openInputStream in class InputBase

Throws:

IOException

of

public static DynamicInputFromStream of(InputStream coreInput)

hasFile

public boolean hasFile()

Specified by:

hasFile in interface DynamicInput

getFile

public Path getFile()
             throws IOException

Description copied from interface: DynamicInput

Return a file (typically a pipe). Calling this function may be create the pipe on-demand, hence the IOException. Use DynamicInput.hasFile() to check for file backing without on-demand creation.

Specified by:

getFile in interface DynamicInput

Throws:

IOException

upgrade

protected void upgrade()
                throws IOException

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

Throws:
