Tests whether a property exists or not. This can be less expensive than getValue(String), because it does not have to allocate an Object for the property value.

get

operator fun DictionaryInterface.get(key: String): Fragment

Subscript access to a Fragment object of the projecting result value for the given key.

getArray

abstract fun getArray(key: String): Array?

Get a property's value as an Array. Returns null if the property doesn't exist, or its value is not an array.

getBlob

abstract fun getBlob(key: String): Blob?

Gets a property's value as a Blob. Returns null if the value doesn't exist, or its value is not a Blob.

getBoolean

abstract fun getBoolean(key: String): Boolean

Gets a property's value as a boolean. Returns true if the value exists, and is either true or a nonzero number.

getDate

abstract fun getDate(key: String): Instant?

Gets a property's value as an Instant date. JSON does not directly support dates, so the actual property value must be a string, which is then parsed according to the ISO-8601 date format (the default used in JSON.) Returns null if the value doesn't exist, is not a string, or is not parsable as a date. NOTE: This is not a generic date parser! It only recognizes the ISO-8601 format, with or without milliseconds.

getDictionary

abstract fun getDictionary(key: String): Dictionary?

Get a property's value as a Dictionary. Returns null if the property doesn't exist, or its value is not a dictionary.

getDouble

abstract fun getDouble(key: String): Double

Gets a property's value as a double. Integers will be converted to double. The value true is returned as 1.0, false as 0.0. Returns 0.0 if the property doesn't exist or does not have a numeric value.

getFloat

abstract fun getFloat(key: String): Float

Gets a property's value as a float. Integers will be converted to float. The value true is returned as 1.0, false as 0.0. Returns 0.0 if the value doesn't exist or does not have a numeric value.

getInt

abstract fun getInt(key: String): Int

Gets a property's value as an int. Floating point values will be rounded. The value true is returned as 1, false as 0. Returns 0 if the value doesn't exist or does not have a numeric value.

getLong

abstract fun getLong(key: String): Long

Gets a property's value as a long. Floating point values will be rounded. The value true is returned as 1, false as 0. Returns 0 if the value doesn't exist or does not have a numeric value.

getNumber

abstract fun getNumber(key: String): Number?

Gets a property's value as a Number. Returns null if the value doesn't exist, or its value is not a Number.

getString

abstract fun getString(key: String): String?

Gets a property's value as a String. Returns null if the value doesn't exist, or its value is not a String.

getValue

abstract fun getValue(key: String): Any?

Gets a property's value as an object. The object types are Blob, Array, Dictionary, Number, or String based on the underlying data type; or null if the property value is null or the property doesn't exist.

toJSON

abstract fun toJSON(): String

Encode a Dictionary as a JSON string

toMap

abstract fun toMap(): Map<String, Any?>

Gets content of the current object as a Map. The values contained in the returned Map object are all JSON based values.
