Public methods

describeContents

public int describeContents ()

Implement the Parcelable interface

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getAttributes

public Map<String, byte[]> getAttributes ()

Retrieve attributes as a map of String keys to byte[] values. The attributes map is only valid for a resolved service.

The returned map is unmodifiable; changes must be made through setAttribute(String, String) and removeAttribute(String).

Returns
Map<String, byte[]>

getHost

public InetAddress getHost ()

Get the host address. The host address is valid for a resolved service.

Returns
InetAddress

getPort

public int getPort ()

Get port number. The port number is valid for a resolved service.

Returns
int

getServiceName

public String getServiceName ()

Get the service name

Returns
String

getServiceType

public String getServiceType ()

Get the service type

Returns
String

removeAttribute

public void removeAttribute (String key)

Remove an attribute by key

Parameters
key String

setAttribute

public void setAttribute (String key, 
                String value)

Add a service attribute as a key/value pair.

Service attributes are included as DNS-SD TXT record pairs.

The key must be US-ASCII printable characters, excluding the '=' character. Values may be UTF-8 strings or null. The total length of key + value must be less than 255 bytes.

Keys should be short, ideally no more than 9 characters, and unique per instance of NsdServiceInfo. Calling setAttribute(String, String) twice with the same key will overwrite first value.

Parameters
key String

value String

setHost

public void setHost (InetAddress s)

Set the host address

Parameters
s InetAddress

setPort

public void setPort (int p)

Set port number

Parameters
p int

setServiceName

public void setServiceName (String s)

Set the service name

Parameters
s String

setServiceType

public void setServiceType (String s)

Set the service type

Parameters
s String

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Implement the Parcelable interface

Parameters
dest Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
