DacpMethodTableData Structure

Defines a transport buffer for method table information.

Note

This API was originally designed for internal use in the runtime. Although it is now supported for 3rd party use, we recommend working with ICorDebug and ICorProfiler APIs when possible.

Syntax

struct DacpMethodTableData : ZeroInit<DacpMethodTableData>
{
    BOOL bIsFree; // everything else is NULL if this is true.
    CLRDATA_ADDRESS Module;
    CLRDATA_ADDRESS Class;
    CLRDATA_ADDRESS ParentMethodTable;
    WORD wNumInterfaces;
    WORD wNumMethods;
    WORD wNumVtableSlots;
    WORD wNumVirtuals;
    DWORD BaseSize;
    DWORD ComponentSize;
    mdTypeDef cl; // Metadata token    
    DWORD dwAttrClass; // cached metadata
    BOOL bIsShared; // flags & enum_flag_DomainNeutral
    BOOL bIsDynamic;
    BOOL bContainsPointers;
    
    HRESULT Request(ISOSDacInterface *sos, CLRDATA_ADDRESS addr)
    {
        return sos->GetMethodTableData(addr, this);
    }
};

Members

Member Description
bIsFree A value that indicates whether the method table is free. If this member is TRUE, all other members are NULL.
Module The address of the module that contains the method table.
Class The address of the EEClass for the method table.
ParentMethodTable The address of the parent method table.
wNumInterfaces The number of interfaces implemented by the type.
wNumMethods The number of methods on the method table.
wNumVtableSlots The number of vtable slots on the method table.
wNumVirtuals The number of virtual methods on the method table.
BaseSize The base size for instances of the type.
ComponentSize The component size for array or string instances.
cl The metadata token for the type.
dwAttrClass The cached metadata attributes for the type.
bIsShared A value that indicates whether the method table is shared.
bIsDynamic A value that indicates whether the method table represents a dynamic type.
bContainsPointers A value that indicates whether instances of the type contain object references.
Request Populates the structure from a method table address by calling ISOSDacInterface::GetMethodTableData.
