PropertyConfig

abstract class PropertyConfig
kotlin.Any
   ↳ android.app.appsearch.AppSearchSchema.PropertyConfig

Common configuration for a single property (field) in a Document.

For example, an EmailMessage would be a type and the subject would be a property.

Public methods

equals

Added in API level 31
open fun equals(other: Any?): Boolean

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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

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
obj the reference object with which to compare.
other Any?: This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getCardinality

Added in API level 31
open fun getCardinality(): Int

Returns the cardinality of the property (whether it is optional, required or repeated).

Return
Int Value is android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_REPEATED, android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_OPTIONAL, or android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_REQUIRED

getDescription

Added in API level Baklava
open fun getDescription(): String

Returns a natural language description of this property.

Ex. The description for the "homeAddress" property of a "Person" type could be "the address at which this person lives".

This information is purely to help apps consuming this type the semantic meaning of its properties. This field has no effect in AppSearch - it is just stored with the AppSearchSchema. If the description is not set, then this method will return an empty string.

Return
String This value cannot be null.

getName

Added in API level 31
open fun getName(): String

Returns the name of this property.

Return
String This value cannot be null.

hashCode

Added in API level 31
open fun hashCode(): Int
Return
Int a hash code value for this object.

toString

Added in API level 31
open fun toString(): String

Returns a string representation of the object.

Return
String This value cannot be null.
