LSDATypeTable

public LSDATypeTable(TaskMonitor monitor,
                     Program program,
                     RegionDescriptor region)

Constructor for a table of references to types that are associated with catch actions.
Note: The create(Address, Address) method must be called after constructing an LSDATypeTable to associate it with an address before any of its "get..." methods are called.

Parameters:

monitor - task monitor to see if the user has cancelled analysis.

program - the program containing the type table.

region - the region of the program associated with this type table.

Method Detail

create

public void create(Address bottom,
                   Address top)

Create a LSDA Type Table from the bytes between bottom and top. This table is built from bottom-to-top.
Note: This method must get called before any of the "get..." methods.

Parameters:

bottom - the bottom address of the type table

top - the top address of the type table

getTypeInfoAddress

public Address getTypeInfoAddress(int index)

Gets the address of the type information from the reference record at the specified index in the table.

Parameters:

index - the index (1-based) of the type info table record.

Returns:

the address of the type info.

getNextAddress

public Address getNextAddress()

Gets the address after this type table.

Returns:

the next address after this type table or null if this type table hasn't been created at any address yet.
