java.lang.Object

java.io.Writer

org.apache.johnzon.core.Snippet.PassthroughWriter

org.apache.johnzon.core.Snippet.Buffer.SnippetWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable, Buffered

Enclosing class:

Snippet.Buffer

class Snippet.Buffer.SnippetWriter
extends Snippet.PassthroughWriter
implements Buffered

Specialized Writer with three internal states: Writing, Completed, Truncated. When there is still space left for more json, the state will be Writing If the last write brought is exactly to the end of the max length, the state will be Completed. If the last write brought us over the max length, the state will be Truncated.

Modifier and Type	Class	Description
(package private) class	Snippet.Buffer.SnippetWriter.Completed	Signifies the last write was fully written, but there is no more space for future writes.
(package private) class	Snippet.Buffer.SnippetWriter.Truncated	Signifies the last write was not completely written and there was no more space for this or future writes.
(package private) class	Snippet.Buffer.SnippetWriter.Writing

Method Detail

get

public String get()

bufferSize

public int bufferSize()

Description copied from interface: Buffered

The buffer size used by this stream while reading input or before writing output to the underlying stream.

Specified by:

bufferSize in interface Buffered

Returns:

the size of the buffer

terminate

public boolean terminate()

Calling this method implies the need to continue writing and a question on if that is ok. It impacts internal state in the same way as calling a write method.

Returns:

true if no more writes are possible

isTruncated

public boolean isTruncated()

write

public void write(char[] cbuf,
                  int off,
                  int len)
           throws IOException

Specified by:

write in class Writer

Throws:

IOException

flush

public void flush()
           throws IOException

Specified by:

flush in interface Flushable

Overrides:

flush in class Snippet.PassthroughWriter

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class Snippet.PassthroughWriter

Throws:

IOException
