describeContents
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.

equals
public boolean equals (Object o)
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 returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
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. |
getAuthor
public String getAuthor ()
Returns the author of the message.
| Returns | |
|---|---|
String |
This value cannot be null. |
getContextData
public ChatMessageContextData getContextData ()
Returns the context metadata associated with this message, if any.
| Returns | |
|---|---|
ChatMessageContextData |
This value may be null. |
getReferenceTimeMillis
public long getReferenceTimeMillis ()
Returns the timestamp of when the message was sent or received in milliseconds since epoch.
This timestamp represents when the message content was detected.
| Returns | |
|---|---|
long |
|
getText
public String getText ()
Returns the text of the message.
| Returns | |
|---|---|
String |
This value cannot be null. |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
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
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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
equalsmethod, then calling thehashCodemethod 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
equalsmethod, then calling thehashCodemethod 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. |
isOutgoingMessage
public boolean isOutgoingMessage ()
Returns true if this is an outgoing message, and false otherwise.
| Returns | |
|---|---|
boolean |
|
toString
public String toString ()
Returns a string representation of the object.
| Returns | |
|---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
dest |
Parcel: This value cannot be null. |
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 the following:
