A dense indexed sequence of values.

public class JSONArray : Java.Lang.Object

type JSONArray = class
    inherit Object

Inheritance: Object

JSONArray

Attributes: RegisterAttribute

Remarks

A dense indexed sequence of values. Values may be any mix of JSONObject JSONObjects, other JSONArray JSONArrays, Strings, Booleans, Integers, Longs, Doubles, null or JSONObject#NULL. Values may not be Double#isNaN() NaNs, Double#isInfinite() infinities, or of any type not listed here.

JSONArray has the same type coercion behavior and optional/mandatory accessors as JSONObject. See that class' documentation for details.

<strong>Warning:</strong> this class represents null in two incompatible ways: the standard Java null reference, and the sentinel value JSONObject#NULL. In particular, get fails if the requested index holds the null reference, but succeeds if it holds JSONObject.NULL.

Instances of this class are not thread safe. Although this class is nonfinal, it was not designed for inheritance and should not be subclassed. In particular, self-use by overridable methods is not specified. See Effective Java Item 17, "Design and Document or inheritance or else prohibit it" for further information.

Constructors

JSONArray()	Creates a `JSONArray` with no values.
JSONArray(ICollection)	Creates a new `JSONArray` by copying all values from the given collection.
JSONArray(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.
JSONArray(JSONTokener)	Creates a new `JSONArray` with values from the next array in the tokener.
JSONArray(Object)	Creates a new `JSONArray` with values from the given primitive array.
JSONArray(String)	Creates a new `JSONArray` with values from the JSON string.

Properties

Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
Get(Int32)	Returns the value at `index`.
GetBoolean(Int32)	Returns the value at `index` if it exists and is a boolean or can be coerced to a boolean.
