Method Detail

attachToMemory

void attachToMemory(byte[] blobMemory,
                    int size,
                    int transferOwnership)
                    throws IOException,
                           AutomationException

Attaches the stream to memory. If transferOwnership is true, memory must be allocated with HeapAlloc() using GetProcessHeap().

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

blobMemory - An unsigned byte (in)

size - The size (in)

transferOwnership - The transferOwnership (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

importFromMemory

void importFromMemory(byte[] blobMemory,
                      int size)
                      throws IOException,
                             AutomationException

Import using another blob.
