public static final Creator<Characteristics> CREATOR

Public methods

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

int getMaxMatchFilterLength()

Returns the maximum length of byte array that can be used to specify a Aware match filter.

int getMaxServiceNameLength()

Returns the maximum string length that can be used to specify a Aware service name.

int getMaxServiceSpecificInfoLength()

Returns the maximum length of byte array that can be used to specify a Aware service specific information field: the arbitrary load used in discovery or the message length of Aware message exchange.

Fields

CREATOR

added in API level 26
public static final Creator<Characteristics> CREATOR

Public methods

describeContents

added in API level 26
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

getMaxMatchFilterLength

added in API level 26
public int getMaxMatchFilterLength ()

Returns the maximum length of byte array that can be used to specify a Aware match filter. Restricts the parameters of the PublishConfig.Builder.setMatchFilter(java.util.List) and SubscribeConfig.Builder.setMatchFilter(java.util.List).

Returns
int A positive integer, maximum legngth of byte array for Aware discovery match filter.

getMaxServiceNameLength

added in API level 26
public int getMaxServiceNameLength ()

Returns the maximum string length that can be used to specify a Aware service name. Restricts the parameters of the PublishConfig.Builder.setServiceName(String) and SubscribeConfig.Builder.setServiceName(String).

Returns
int A positive integer, maximum string length of Aware service name.

getMaxServiceSpecificInfoLength

added in API level 26
public int getMaxServiceSpecificInfoLength ()

Returns the maximum length of byte array that can be used to specify a Aware service specific information field: the arbitrary load used in discovery or the message length of Aware message exchange. Restricts the parameters of the PublishConfig.Builder.setServiceSpecificInfo(byte[]), SubscribeConfig.Builder.setServiceSpecificInfo(byte[]), and DiscoverySession.sendMessage(PeerHandle, int, byte[]) variants.

Returns
int A positive integer, maximum length of byte array for Aware messaging.

writeToParcel

added in API level 26
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

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.
