Method Detail
-
flush
private void flush(StreamChannel<java.nio.ByteBuffer> channel) throws java.io.IOException
- Throws:
java.io.IOException
-
writeData
final int writeData(StreamChannel<java.nio.ByteBuffer> channel, java.nio.ByteBuffer src) throws java.io.IOException
- Throws:
java.io.IOException
-
streamEnd
final void streamEnd(StreamChannel<java.nio.ByteBuffer> channel) throws java.io.IOException
- Throws:
java.io.IOException
-
availableData
protected abstract int availableData()
Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.- Returns:
- the number of bytes immediately available for output
-
produceData
protected abstract void produceData(StreamChannel<java.nio.ByteBuffer> channel) throws java.io.IOException
Triggered to signal the ability of the underlying byte channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.StreamChannel
passed to this method is threading-safe.- Parameters:
channel
- the data channel capable to accepting more data.- Throws:
java.io.IOException
-
getContentType
public final java.lang.String getContentType()
Description copied from interface:EntityDetails
Returns content type of the entity, if known.- Specified by:
getContentType
in interfaceEntityDetails
-
getContentEncoding
public java.lang.String getContentEncoding()
Description copied from interface:EntityDetails
Returns content encoding of the entity, if known.- Specified by:
getContentEncoding
in interfaceEntityDetails
-
isChunked
public boolean isChunked()
Description copied from interface:EntityDetails
Returns chunked transfer hint for this entity.The behavior of wrapping entities is implementation dependent, but should respect the primary purpose.
- Specified by:
isChunked
in interfaceEntityDetails
-
getTrailerNames
public java.util.Set<java.lang.String> getTrailerNames()
Description copied from interface:EntityDetails
Preliminary declaration of trailing headers.- Specified by:
getTrailerNames
in interfaceEntityDetails
-
getContentLength
public long getContentLength()
Description copied from interface:EntityDetails
Returns length of the entity, if known.- Specified by:
getContentLength
in interfaceEntityDetails
-
available
public final int available()
Description copied from interface:AsyncDataProducer
Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.- Specified by:
available
in interfaceAsyncDataProducer
- Returns:
- the number of bytes immediately available for output
-
produce
public final void produce(DataStreamChannel channel) throws java.io.IOException
Description copied from interface:AsyncDataProducer
Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.- Specified by:
produce
in interfaceAsyncDataProducer
- Parameters:
channel
