class Unserializer

package haxe

Available on all platforms

The Unserializer class is the complement to the Serializer class. It parses a serialization String and creates objects from the contained data.

This class can be used in two ways:

  • create a new Unserializer() instance with a given serialization String, then call its unserialize() method until all values are extracted
  • call Unserializer.run() to unserialize a single value from a given String

The specification of the serialization format can be found here: https://haxe.org/manual/serialization/format

Static variables

@:value(new DefaultResolver())@:keep@:keepstaticDEFAULT_RESOLVER:TypeResolver = new DefaultResolver()

This value can be set to use custom type resolvers.

A type resolver finds a Class or Enum instance from a given String. By default, the Haxe Type Api is used.

A type resolver must provide two methods:

  1. resolveClass(name:String):Class<Dynamic> is called to determine a

    `Class` from a class name

  2. resolveEnum(name:String):Enum<Dynamic> is called to determine an

    `Enum` from an enum name

This value is applied when a new Unserializer instance is created. Changing it afterwards has no effect on previously created instances.

Static methods

@:keep@:keepstaticrun(v:String):Dynamic

Unserializes v and returns the according value.

This is a convenience function for creating a new instance of Unserializer with v as buffer and calling its unserialize() method once.

Constructor

@:keep@:keepnew(buf:String)

Creates a new Unserializer instance, with its internal buffer initialized to buf.

This does not parse buf immediately. It is parsed only when calls to this.unserialize are made.

Each Unserializer instance maintains its own cache.

Methods

@:keep@:keepgetResolver():TypeResolver

Gets the type resolver of this Unserializer instance.

See DEFAULT_RESOLVER for more information on type resolvers.

@:keep@:keepsetResolver(r:Null<TypeResolver>):Void

Sets the type resolver of this Unserializer instance to r.

If r is null, a special resolver is used which returns null for all input values.

See DEFAULT_RESOLVER for more information on type resolvers.

@:keep@:keepunserialize():Dynamic

Unserializes the next part of this Unserializer instance and returns the according value.

This function may call this.resolver.resolveClass to determine a Class from a String, and this.resolver.resolveEnum to determine an Enum from a String.

If this Unserializer instance contains no more or invalid data, an exception is thrown.

This operation may fail on structurally valid data if a type cannot be resolved or if a field cannot be set. This can happen when unserializing Strings that were serialized on a different Haxe target, in which the serialization side has to make sure not to include platform-specific data.

Classes are created from Type.createEmptyInstance, which means their constructors are not called.
