TAG

String TAG

Constant Value: "ContentValues"

CREATOR

Creator<ContentValues> CREATOR

ContentValues

ContentValues ()

Creates an empty set of values using the default initial size

ContentValues

ContentValues (int size)

Creates an empty set of values using the given initial size

ContentValues

ContentValues (ContentValues from)

Creates a set of values copied from the given set

clear

void clear ()

Removes all values.

containsKey

boolean containsKey (String key)

Returns true if this object has the named value.

describeContents

int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

equals

boolean equals (Object object)

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

get

Object get (String key)

Gets a value. Valid value types are String, Boolean, Number, and byte[] implementations.

getAsBoolean

Boolean getAsBoolean (String key)

Gets a value and converts it to a Boolean.

getAsByte

Byte getAsByte (String key)

Gets a value and converts it to a Byte.

getAsByteArray

byte[] getAsByteArray (String key)

Gets a value that is a byte array. Note that this method will not convert any other types to byte arrays.

getAsDouble

Double getAsDouble (String key)

Gets a value and converts it to a Double.

getAsFloat

Float getAsFloat (String key)

Gets a value and converts it to a Float.

getAsInteger

Integer getAsInteger (String key)

Gets a value and converts it to an Integer.

getAsLong

Long getAsLong (String key)

Gets a value and converts it to a Long.

getAsShort

Short getAsShort (String key)

Gets a value and converts it to a Short.

getAsString

String getAsString (String key)

Gets a value and converts it to a String.

hashCode

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 in equals 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(Object) method, then calling the hashCode 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(java.lang.Object) method, then calling the hashCode 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)
