Method Summary

Modifier and TypeMethod and Description
public NextAction

Returns:

the next action
handleClose(FilterChainContext
Context of FilterChainContext processing.
ctx)

Overrides org.glassfish.grizzly.filterchain.BaseFilter.handleClose.

Implements org.glassfish.grizzly.filterchain.Filter.handleClose.

Method perform the clean up of GZIP encoding/decoding state on a closed Connection.

public NextAction

Returns:

the next action
handleRead(FilterChainContext
Context of FilterChainContext processing.
ctx)

Overrides org.glassfish.grizzly.filterchain.BaseFilter.handleRead.

Implements org.glassfish.grizzly.filterchain.Filter.handleRead.

Method decodes GZIP encoded data stored in FilterChainContext#getMessage() and, as the result, produces a Buffer with a plain data.
