BinaryDataSource

public BinaryDataSource()

Method Detail

getString0

public final java.lang.String getString0(int address)

Load a zero-terminated string from memory. Encoding is assumed to be ISO-8859-1.

Parameters:

address -

Returns:

String loaded

getString0_10_13

public final java.lang.String getString0_10_13(int address)

getStringControlTerminated

public final java.lang.String getStringControlTerminated(int offset)

getStringControlTerminated

public final java.lang.String getStringControlTerminated(int offset,
                                                         int length)

getStringN

public final java.lang.String getStringN(int offset,
                                         int maxLength)

getByteArray

public abstract ByteArray getByteArray(int address,
                                       int count,
                                       boolean create)

Get an object which allows direct access to the underlying data block for the specified byte range.

Parameters:

address - address for which to find bytes

count - size of byte block to allow access to

create -

Returns:

ByteArray which reads/writes through to underlying data block.

getBytes

public abstract byte[] getBytes(int address,
                                int count)

Take a copy of a set of bytes from the memory map. Use getByteArray(int,int,boolean) instead for efficiency.

Parameters:

address - address at which to load bytes

count - number of bytes to load

Returns:

array containing bytes loaded from specified address

get5ByteValue

public abstract long get5ByteValue(int address)

getWords

public abstract int[] getWords(int address,
                               int count)
