java.lang.Object | |
↳ | android.app.appsearch.AppSearchSchema |
The AppSearch Schema for a particular type of document.
For example, an e-mail message or a music recording could be a schema type.
The schema consists of type information, properties, and config (like tokenization type).

Public methods
equals
public boolean equals (Object other)
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
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons 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 | |
---|---|
other |
Object : This value may be null . |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getDescription
public String getDescription ()
Returns a natural language description of this schema type.
Ex. The description for an Email type could be "A type of electronic message".
This information is purely to help apps consuming this type to understand its semantic
meaning. This field has no effect in AppSearch - it is just stored with the AppSearchSchema.
If Builder.setDescription
is uncalled, then this method will return an empty string.
Returns | |
---|---|
String |
This value cannot be null . |
getParentTypes
public List<String> getParentTypes ()
Returns the list of parent types of this schema for polymorphism.
Returns | |
---|---|
List<String> |
This value cannot be null . |
getProperties
public List<AppSearchSchema.PropertyConfig> getProperties ()
Returns the list of PropertyConfig
s that are part of this schema.
This method creates a new list when called.
Returns | |
---|---|
List<AppSearchSchema.PropertyConfig> |
This value cannot be null . |
getSchemaType
public String getSchemaType ()
Returns the name of this schema type, such as Email.
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
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons 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
equals
method, then calling thehashCode
method 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
equals
method, then calling thehashCode
method 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 |
This value cannot be null . |
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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
