Constants
MIXER_BEHAVIOR_BIT_PERFECT
public static final int MIXER_BEHAVIOR_BIT_PERFECT
Constant indicating the audio mixer behavior is bit-perfect, which indicates there will not be mixing happen, the audio data will be sent as is down to the HAL.
Constant Value: 1 (0x00000001)
MIXER_BEHAVIOR_DEFAULT
public static final int MIXER_BEHAVIOR_DEFAULT
Constant indicating the audio mixer behavior will follow the default platform behavior, which is mixing all audio sources in the mixer.
Constant Value: 0 (0x00000000)
Fields
Public methods
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(android.os.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.
 Value is either 0orCONTENTS_FILE_DESCRIPTOR | 
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 | trueif this object is the same as the obj
          argument;falseotherwise. | 
getFormat
public AudioFormat getFormat ()
Return the format of the audio mixer. The format is an AudioFormat object, which
 includes encoding format, sample rate and channel mask or channel index mask.
| Returns | |
|---|---|
| AudioFormat | the format of the audio mixer.
 This value cannot be null. | 
getMixerBehavior
public int getMixerBehavior ()
Returns the mixer behavior for this set of mixer attributes.
| Returns | |
|---|---|
| int | the mixer behavior
 Value is MIXER_BEHAVIOR_DEFAULT, orMIXER_BEHAVIOR_BIT_PERFECT | 
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. | 
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 benull. | 
| flags | int: Additional flags about how the object should be written.
 May be 0 orParcelable.PARCELABLE_WRITE_RETURN_VALUE.
 Value is either0or a combination ofParcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
