MutableDictionaryInterface

The number of the entries in the dictionary.

A List containing all keys, or an empty List if the dictionary has no properties.

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.

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

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

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

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

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

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.

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

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.

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.

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.

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.

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

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

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.

Removes the mapping for a key from this Dictionary

Set an Array object for the given key.

Set a Blob object for the given key.

Set a boolean value for the given key.

Populate a dictionary with content from a Map. Allowed value types are List, Instant, Map, Number, null, String, Array, Blob, and Dictionary. If present, Lists, Arrays, Maps and Dictionaries may contain only the above types. Setting the dictionary content will replace the current data including any existing Array and Dictionary objects.

Set a Dictionary object for the given key.

Set a double value for the given key.

Set a float value for the given key.

Set an int value for the given key.

Populate a dictionary with content from a JSON string. Setting the dictionary content will replace the current data including any existing Array and Dictionary objects.

Set a long value for the given key.

Set a Number value for the given key.

Set a String value for the given key.

Set an object value by key. Allowed value types are List, Instant, Map, Number, null, String, Array, Blob, and Dictionary. If present, Lists, Arrays, Maps and Dictionaries may contain only the above types.

Encode a Dictionary as a JSON string

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