Class GuidStream

Namespace
AsmResolver.PE.DotNet.Metadata
Assembly
AsmResolver.PE.dll

Represents the metadata stream containing GUIDs referenced by entries in the tables stream.

public abstract class GuidStream : MetadataHeap, IMetadataStream, ISegment, IOffsetProvider, IWritable
Inheritance
GuidStream
Implements
Derived
Inherited Members

Remarks

Like most metadata streams, the GUID stream does not necessarily contain just valid strings. It can contain (garbage) data that is never referenced by any of the tables in the tables stream. The only guarantee that the GUID heap provides, is that any blob index in the tables stream is the start address (relative to the start of the GUID stream) of a GUID.

Constructors

GuidStream()

Initializes the GUID stream with its default name.

protected GuidStream()

GuidStream(string)

Initializes the GUID stream with a custom name.

protected GuidStream(string name)

Parameters

name string

The name of the stream.

Fields

DefaultName

The default name of a GUID stream, as described in the specification provided by ECMA-335.

public const string DefaultName = "#GUID"

Field Value

string

GuidSize

The size of a single GUID in the GUID stream.

public const int GuidSize = 16

Field Value

int

Methods

EnumerateGuids()

Performs a linear sweep on the stream and yields all GUIDs that are stored.

public abstract IEnumerable<Guid> EnumerateGuids()

Returns

IEnumerable<Guid>

The GUID enumerator.

GetGuidByIndex(uint)

Gets a GUID by its GUID index.

public abstract Guid GetGuidByIndex(uint index)

Parameters

index uint

The offset into the heap to start reading.

Returns

Guid

The GUID.

TryFindGuidIndex(Guid, out uint)

Searches the stream for the provided GUID.

public abstract bool TryFindGuidIndex(Guid guid, out uint index)

Parameters

guid Guid

The GUID to search for.

index uint

When the function returns true, contains the index at which the GUID was found.

Returns

bool

true if the GUID index was found, false otherwise.
