Interface RuntimeTable<T>

All Known Implementing Classes:

FunctionTable, IMT, ITable, ITableArray, LinkageTripletTable, TIB

public interface RuntimeTable<T>

This interface is used to indicate a type will behave as a runtime table. Runtime tables are used to implement arrays whose elements can only be manipulated by the the get and set methods of the table. Every runtime table will have a static allocate method and implement the methods below.

TypeReference.isRuntimeTable()

get

T get(int index)

Get a value from the table. This method is hijacked by the compiler but the implementation is used during boot image writing.

Parameters:

index - location to read

Returns:

value from table

set

void set(int index,
         T value)

Set a value to the table. This method is hijacked by the compiler but the implementation is used during boot image writing.

Parameters:

index - location to write

value - to write

length

int length()

Get the table length. This method is hijacked by the compiler but the implementation is used during boot image writing.

Returns:

length of table

getBacking

T[] getBacking()

Only called at boot image write time. This returns the backing array to the boot image writer.

Returns:

backing array of elements
