Public Methods

public void clear()

Removes all values.

public boolean containsKey(String key)

Returns true if this object has the named value.

Parameters

key the value to check for

Returns

  • true if the value is present, false otherwise

public int describeContents()

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

public boolean equals(Object object)

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. The implementation in Object returns true only if the argument is the exact same object as the receiver (==).

Parameters

object Object the object to compare with this object.

Returns

  • boolean true if the object is the same as this object false if it is different from this object.

public Object get(String key)

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

Parameters

key the value to get

Returns

  • the data for the value

public Boolean getAsBoolean(String key)

Gets a value and converts it to a Boolean.

Parameters

key the value to get

Returns

  • the Boolean value, or null if the value is missing or cannot be converted

public Byte getAsByte(String key)

Gets a value and converts it to a Byte.

Parameters

key the value to get

Returns

  • the Byte value, or null if the value is missing or cannot be converted

public 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.

Parameters

key the value to get

Returns

  • the byte[] value, or null is the value is missing or not a byte[]

public Double getAsDouble(String key)

Gets a value and converts it to a Double.

Parameters

key the value to get

Returns

  • the Double value, or null if the value is missing or cannot be converted
