          org.wings.StaticResource.LimitedBuffer

All Implemented Interfaces:

Closeable, Flushable

Enclosing class:

StaticResource

protected static final class StaticResource.LimitedBuffer
extends ByteArrayOutputStream

An ByteArrayOutputStream that buffers up to the limit MAX_SIZE_TO_BUFFER. Is able to write to an Device.

Field Summary

static int

MAX_SIZE_TO_BUFFER

Fields inherited from class java.io.ByteArrayOutputStream

buf, count

Method Summary

byte[]	getBytes() returns the _raw_ buffer; i.e.
boolean	isValid() returns, whether the filled buffer is within the limits, and thus, its content is valid and can be used.
void	setValid(boolean valid) sets, whether this resource is valid.
void	write(byte[] b, int off, int len) write to the stream.
void	writeTo(Device out) write to some output device.

Method Detail

write

public void write(byte[] b,
                  int off,
                  int len)

write to the stream. If the output size exceeds the limit, then set the stream to error state.

Overrides:

write in class ByteArrayOutputStream

isValid

public boolean isValid()

returns, whether the filled buffer is within the limits, and thus, its content is valid and can be used.

setValid

public void setValid(boolean valid)

sets, whether this resource is valid.

getBytes

public byte[] getBytes()

returns the _raw_ buffer; i.e. the buffer may be larger than the current size().

writeTo

public void writeTo(Device out)
             throws IOException

write to some output device.

Throws:

IOException
