MatrixCursor.RowBuilder

Kotlin |Java

public class MatrixCursor.RowBuilder
extends Object

java.lang.Object
↳	android.database.MatrixCursor.RowBuilder

Builds a row of values using either of these approaches:

Values can be added with explicit column ordering using add(Object), which starts from the left-most column and adds one column value at a time. This follows the same ordering as the column names specified at cursor construction time.
Column and value pairs can be offered for possible inclusion using add(String,Object). If the cursor includes the given column, the value will be set for that column, otherwise the value is ignored. This approach is useful when matching data to a custom projection.

Undefined values are left as null.

Summary

Public methods
`MatrixCursor.RowBuilder`	`add(Object columnValue)` Sets the next column value in this row.
`MatrixCursor.RowBuilder`	`add(String columnName, Object value)` Offer value for possible inclusion if this cursor defines the given column.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Parameters
`columnName`	`String`
`value`	`Object`
