Constructor Details

SymbolEntry

public SymbolEntry(HighSymbol sym)

Constructor for use with restoreXML

Parameters:

sym - is the symbol owning this entry

Method Details

decode NEW

public abstract void decode(Decoder decoder)
                     throws DecoderException

Decode this entry from the stream. Typically more than one element is consumed.

Parameters:

decoder - is the stream decoder

Throws:

DecoderException - for invalid encodings

encode NEW

public abstract void encode(Encoder encoder)
                     throws IOException

Encode this entry as (a set of) elements to the given stream

Parameters:

encoder - is the stream encoder

Throws:

IOException - for errors in the underlying stream

getStorage

public abstract VariableStorage getStorage()

Get the storage associated with this particular mapping of the Symbol

Returns:

the storage object

getSize

public abstract int getSize()

Get the number of bytes consumed by the symbol when using this storage

Returns:

the size of this entry

isReadOnly

public abstract boolean isReadOnly()

Returns:

true if the mapped storage is read-only

isVolatile

public abstract boolean isVolatile()

Returns:

true if the mapped storage is volatile

getPCAdress

public Address getPCAdress()

The storage used to hold this Symbol may be used for other purposes at different points in the code. This returns the earliest address in the code where this storage is used for this symbol

Returns:

the starting address where the Symbol uses this storage

decodeRangeList NEW

protected void decodeRangeList(Decoder decoder)
                        throws DecoderException

Throws:

DecoderException

encodeRangelist NEW

protected void encodeRangelist(Encoder encoder)
                        throws IOException

Throws:

IOException
