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 `0` or `CONTENTS_FILE_DESCRIPTOR`

getBreadCrumbShortTitle

public CharSequence getBreadCrumbShortTitle (Resources res)

Return the currently set bread crumb short title. If breadCrumbShortTitleRes is set, this resource is loaded from res and returned. Otherwise breadCrumbShortTitle is returned.

Parameters
`res`	`Resources`

Returns
`CharSequence`

getBreadCrumbTitle

public CharSequence getBreadCrumbTitle (Resources res)

Return the currently set bread crumb title. If breadCrumbTitleRes is set, this resource is loaded from res and returned. Otherwise breadCrumbTitle is returned.

Parameters
`res`	`Resources`

Returns
`CharSequence`

getSummary

public CharSequence getSummary (Resources res)

Return the currently set summary. If summaryRes is set, this resource is loaded from res and returned. Otherwise summary is returned.

Parameters
`res`	`Resources`

Returns
`CharSequence`

getTitle

public CharSequence getTitle (Resources res)

Return the currently set title. If titleRes is set, this resource is loaded from res and returned. Otherwise title is returned.

Parameters
`res`	`Resources`

Returns
`CharSequence`

readFromParcel

public void readFromParcel (Parcel in)

Parameters
`in`	`Parcel`

writeToParcel

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`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
