Field Detail

Constant Field Values

CREATOR

public static final Parcelable.Creator<ContentValues> CREATOR
Constructor Detail

ContentValues

public ContentValues()
Creates an empty set of values using the default initial size


ContentValues

public ContentValues(int size)
Creates an empty set of values using the given initial size

Parameters:
size - the initial size of the set of values

ContentValues

public ContentValues(ContentValues from)
Creates a set of values copied from the given set

Parameters:
from - the values to copy
Method Detail

equals

public boolean equals(Object object)
Description copied from class: Object
Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be both transitive and reflexive.

The implementation in Object returns true only if o is the exact same object as the receiver (using the == operator for comparison). Subclasses often implement equals(Object) so that it takes into account the two object's types and states.

The general contract for the equals(Object) and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or none of them.

Overrides:
equals in class Object
Parameters:
object - the object to compare this instance with.
Returns:
true if the specified object is equal to this Object; false otherwise.
See Also:
Object.hashCode()

hashCode

public int hashCode()
Description copied from class: Object
Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Overrides:
hashCode in class Object
Returns:
this object's hash code.
See Also:
Object.equals(java.lang.Object)

@Deprecated
public ArrayList<String> getStringArrayList(String key)
Deprecated. 

Unsupported, here until we get proper bulk insert APIs.


toString

public String toString()

 getClass().getName() + '@' + Integer.toHexString(hashCode())
