Constructors

FileChannel()

Default constructor: even if the corresponding Java class does not have one, it is mandatory for JCOBridge

[Obsolete("FileChannel class represents, in .NET, an instance of a JVM interface or abstract class. This public initializer is needed for JCOBridge internal use, other uses can produce unidentible behaviors.")]
public FileChannel()

FileChannel(params object[])

Generic constructor: it is useful for JCOBridge when there is a derived class which needs to pass arguments to the highest JVMBridgeBase class

[Obsolete("FileChannel class represents, in .NET, an instance of a JVM interface or abstract class. This public initializer is needed for JCOBridge internal use, other uses can produce unidentible behaviors.")]
public FileChannel(params object[] args)

Parameters

args object[]
