Public Methods

	Name	Description
	AfterConstruction	Responds after the last constructor has executed.
	BeforeDestruction	Responds before the first destructor executes.
	ClassInfo	Returns a pointer to the runtime type information (RTTI) table for the object type.

	ClassNameIs	Determines whether an object is of a specific type.
	ClassParent	Returns the type of the immediate ancestor of a class.
	ClassType	Returns the class reference for the object's class.
	CleanupInstance	Performs finalization on long strings, variants, and interface variables within a class.
	CopyFrom	Copies a specified number of bytes from one stream to another.
	Create	This is the overview for the Create constructor overload.
	DefaultHandler	Provides the interface for a method that processes message records.
	Destroy	Destroys the TZCompressionStream object.
	Dispatch	Calls message-handling methods for the object, based on the contents of the Message parameter.
	Equals	Checks if the current instance and the parameter are equal.
	FieldAddress	This is the overview for the FieldAddress method overload.
	FixupResourceHeader	Patches the resource header for a resource that has been written to the stream.
	Free	Destroys an object and frees its associated memory, if necessary.
	FreeInstance	Deallocates memory allocated by a previous call to the System::TObject::NewInstance method.
	GetHashCode	Returns an integer containing the hash code.
	GetInterface	Retrieves a specified interface.
	GetInterfaceEntry	Returns the entry for a specific interface implemented in a class.
	GetInterfaceTable	Returns a pointer to a structure containing all of the interfaces implemented by a given class.
	InheritsFrom	Determines the relationship of two object types.
	InitInstance	Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
	InstanceSize	Returns the size in bytes of each instance of the object type.
	MethodAddress	This is the overview for the MethodAddress method overload.
	MethodName	Returns the name of a class method by address.
	NewInstance	Allocates memory for an instance of an object type and returns a pointer to that new instance.
	Read	Raises an exception of type ECompressionError.
	ReadBuffer	Reads bytes from the stream into Buffer.
	ReadComponent	Initiates streaming of components and their properties.
	ReadComponentRes	Reads components and their properties from a stream in a resource file format.
	ReadResHeader	Reads a resource-file header from the stream.
	SafeCallException	Handles exceptions in methods declared using the safecall calling convention.
	Seek	Raises an exception of type ECompressionErrror.
	Seek	This is the overview for the Seek method overload.
	ToString	Returns a string containing the class name.
	UnitName	Returns a string containing the unit name.
	Write	Writes compressed data to the destination output stream.
	WriteBuffer	Writes Count bytes from Buffer onto the stream and advances the current position of the stream by Count bytes.
	WriteComponent	Initiates the writing of components and their properties to a stream.
	WriteComponentRes	Writes components and their properties to a stream from a resource file format.
	WriteDescendent	Streams components and their properties in inherited forms.
	WriteDescendentRes	Streams components and their properties in inherited forms.
	WriteResourceHeader	Writes a resource-file header to the stream.

Public Properties

	Name	Description
	CompressionRate	Returns the percentage by which the data has been compressed.
	Position	Indicates the current offset into the stream for reading and writing.
	Size	Indicates the size in bytes of the stream.
