Builder for PcapWriteHandler

方法概要

限定符和类型	方法和说明
PcapWriteHandler	build(java.io.OutputStream outputStream) Build the PcapWriteHandler.
PcapWriteHandler.Builder	captureZeroByte(boolean captureZeroByte) Set to true to enable capturing packets with empty (0 bytes) payload.
PcapWriteHandler.Builder	forceTcpChannel(java.net.InetSocketAddress serverAddress, java.net.InetSocketAddress clientAddress, boolean isServerPipeline) Force this handler to write data as if they were TCP packets, with the given connection metadata.
PcapWriteHandler.Builder	forceUdpChannel(java.net.InetSocketAddress localAddress, java.net.InetSocketAddress remoteAddress) Force this handler to write data as if they were UDP packets, with the given connection metadata.
PcapWriteHandler.Builder	sharedOutputStream(boolean sharedOutputStream) Set to true if multiple PcapWriteHandler instances will be writing to the same OutputStream concurrently, and write locking is required.
PcapWriteHandler.Builder	writePcapGlobalHeader(boolean writePcapGlobalHeader) Set to true to write Pcap Global Header on initialization.

方法详细资料

captureZeroByte

public PcapWriteHandler.Builder captureZeroByte(boolean captureZeroByte)

Set to true to enable capturing packets with empty (0 bytes) payload. Otherwise, if set to false, empty packets will be filtered out.

参数:

captureZeroByte - Whether to filter out empty packets.

返回:

this builder

sharedOutputStream

public PcapWriteHandler.Builder sharedOutputStream(boolean sharedOutputStream)

Set to true if multiple PcapWriteHandler instances will be writing to the same OutputStream concurrently, and write locking is required. Otherwise, if set to false, no locking will be done. Additionally, PcapWriteHandler.close() will not close the underlying OutputStream. Note: it is probably an error to have both writePcapGlobalHeader and sharedOutputStream set to true at the same time.

参数:

sharedOutputStream - Whether OutputStream is shared or not

返回:

this builder

writePcapGlobalHeader

public PcapWriteHandler.Builder writePcapGlobalHeader(boolean writePcapGlobalHeader)

Set to true to write Pcap Global Header on initialization. Otherwise, if set to false, Pcap Global Header will not be written on initialization. This could when writing Pcap data on a existing file where Pcap Global Header is already present.

参数:

writePcapGlobalHeader - Whether to write the pcap global header.

返回:

this builder

forceTcpChannel

public PcapWriteHandler.Builder forceTcpChannel(java.net.InetSocketAddress serverAddress,
                                                java.net.InetSocketAddress clientAddress,
                                                boolean isServerPipeline)

Force this handler to write data as if they were TCP packets, with the given connection metadata. If this method isn't called, we determine the metadata from the channel.

参数:

serverAddress - The address of the TCP server (handler)

clientAddress - The address of the TCP client (initiator)

isServerPipeline - Whether the handler is part of the server channel

返回:

this builder

forceUdpChannel

public PcapWriteHandler.Builder forceUdpChannel(java.net.InetSocketAddress localAddress,
                                                java.net.InetSocketAddress remoteAddress)

Force this handler to write data as if they were UDP packets, with the given connection metadata. If this method isn't called, we determine the metadata from the channel.
Note that even if this method is called, the address information on DatagramPacket takes precedence if it is present.

参数:

localAddress - The address of the UDP local

remoteAddress - The address of the UDP remote

返回:

this builder

build

public PcapWriteHandler build(java.io.OutputStream outputStream)

Build the PcapWriteHandler.

参数:

outputStream - The output stream to write the pcap data to.

返回:

The handler.
