public boolean

the reference object with which to compare.

Overrides java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

public static LocalForwardingEntry
findMatchingEntry(String host, int port, Collection<? extends LocalForwardingEntry> entries)

public static LocalForwardingEntry

Returns:

The first entry whose local or bound address matches the host name - case insensitive and has a matching bound port - null if no match found
findMatchingEntry
(String
The host - ignored if null/empty and not wildcard address match - i.e., no match reported
host
,
boolean
Is host the wildcard address - in which case, we try an exact match first for the host, and if that fails then only the port is matched
anyLocalAddress
,
int
The port - ignored if non-positive - i.e., no match reported
port
,
Collection<? extends LocalForwardingEntry>
The Collection of LocalForwardingEntry to check - ignored if null/empty - i.e., no match reported
entries
)

public SshdSocketAddress

Returns:

The actual bound address
getBoundAddress
()

public SshdSocketAddress

Returns:

Combined result
getCombinedBoundAddress
()

A combined address using the following logic:

  • If original requested local binding has a specific port and non-wildcard address then use the local binding as-is
  • If original requested local binding has a specific address but no specific port, then combine its address with the actual auto-allocated port at binding.
  • If original requested local binding has neither a specific address nor a specific port then use the effective bound address.
public SshdSocketAddress

Returns:

The original requested local address for binding
getLocalAddress

public int
hashCode()

Overrides java.lang.Object.hashCode.

Returns a hash code value for this object.

public static SshdSocketAddress
public String
toString()

Overrides java.lang.Object.toString.

Returns a string representation of the object.

equalsback to summary
public boolean equals(Object o)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

public static LocalForwardingEntry findMatchingEntry(String host, boolean anyLocalAddress, int port, Collection<? extends LocalForwardingEntry> entries)
Parameters
host:String

The host - ignored if null/empty and not wildcard address match - i.e., no match reported

anyLocalAddress:boolean

Is host the wildcard address - in which case, we try an exact match first for the host, and if that fails then only the port is matched

port:int

The port - ignored if non-positive - i.e., no match reported

entries:Collection<? extends LocalForwardingEntry>

The Collection of LocalForwardingEntry to check - ignored if null/empty - i.e., no match reported

Returns:LocalForwardingEntry

The first entry whose local or bound address matches the host name - case insensitive and has a matching bound port - null if no match found

public SshdSocketAddress getBoundAddress()
Returns:SshdSocketAddress

getCombinedBoundAddressback to summary
public SshdSocketAddress getCombinedBoundAddress()

A combined address using the following logic:

  • If original requested local binding has a specific port and non-wildcard address then use the local binding as-is
  • If original requested local binding has a specific address but no specific port, then combine its address with the actual auto-allocated port at binding.
  • If original requested local binding has neither a specific address nor a specific port then use the effective bound address.
getLocalAddressback to summary
public SshdSocketAddress getLocalAddress()
Returns:SshdSocketAddress

The original requested local address for binding

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
