GetSchemaResponse.Builder

Builder

public Builder ()

Create a Builder object}

addSchema

public GetSchemaResponse.Builder addSchema (AppSearchSchema schema)

Adds one AppSearchSchema to the schema list.

addSchemaTypeNotDisplayedBySystem

public GetSchemaResponse.Builder addSchemaTypeNotDisplayedBySystem (String schemaType)

Sets whether or not documents from the provided schemaType will be displayed and visible on any system UI surface.

build

public GetSchemaResponse build ()

Builds a GetSchemaResponse object.

setPubliclyVisibleSchema

public GetSchemaResponse.Builder setPubliclyVisibleSchema (String schemaType, 
                PackageIdentifier packageIdentifier)

Specify that the schema should be publicly available, to packages which already have visibility to packageIdentifier.

setRequiredPermissionsForSchemaTypeVisibility

public GetSchemaResponse.Builder setRequiredPermissionsForSchemaTypeVisibility (String schemaType, 
                Set<Set<Integer>> visibleToPermissionSets)

Sets a set of required Manifest.permission combinations to the given schema type.

The querier could read the GenericDocument objects under the schemaType if they holds ALL required permissions of ANY of the individual value sets.

For example, if the Map contains {{permissionA, PermissionB}, {PermissionC, PermissionD}, {PermissionE}}.

• A querier holds both PermissionA and PermissionB has access.
• A querier holds both PermissionC and PermissionD has access.
• A querier holds only PermissionE has access.
• A querier holds both PermissionA and PermissionE has access.
• A querier holds only PermissionA doesn't have access.
• A querier holds both PermissionA and PermissionC doesn't have access.

setSchemaTypeVisibleToConfigs

public GetSchemaResponse.Builder setSchemaTypeVisibleToConfigs (String schemaType, 
                Set<SchemaVisibilityConfig> visibleToConfigs)

Sets the documents from the provided schemaType can be read by the caller if they match the ALL visibility requirements set in SchemaVisibilityConfig.

The requirements in a SchemaVisibilityConfig is "AND" relationship. A caller must match ALL requirements to access the schema. For example, a caller must hold required permissions AND it is a specified package.

The querier could have access if they match ALL requirements in ANY of the given SchemaVisibilityConfigs

For example, if the Set contains {{PackageA and Permission1}, {PackageB and Permission2}}.

• A querier from packageA could read if they holds Permission1.
• A querier from packageA could NOT read if they only holds Permission2 instead of Permission1.
• A querier from packageB could read if they holds Permission2.
• A querier from packageC could never read.
• A querier holds both PermissionA and PermissionE has access.

setSchemaTypeVisibleToPackages

public GetSchemaResponse.Builder setSchemaTypeVisibleToPackages (String schemaType, 
                Set<PackageIdentifier> packageIdentifiers)

Sets whether or not documents from the provided schemaType can be read by the specified package.

Each package is represented by a PackageIdentifier, containing a package name and a byte array of type PackageManager.CERT_INPUT_SHA256.

To opt into one-way data sharing with another application, the developer will need to explicitly grant the other application\u2019s package name and certificate Read access to its data.

For two-way data sharing, both applications need to explicitly grant Read access to one another.

setVersion

public GetSchemaResponse.Builder setVersion (int version)

Sets the database overall schema version.

Default version is 0
