Constructor Detail

ValueGetter

public ValueGetter(ByteGetter data,
                   byte endian)

Constructs an instance.

Parameters:

data - ByteGetter

endian - endianess

Method Detail

getValueGetterForEndian

public static ValueGetter getValueGetterForEndian(ByteGetter bytes)

Get the appropriate ValueGetter for the given endianness.

Parameters:

bytes - ByteGetter

Returns:

ValueGetter

Throws:

java.lang.IllegalArgumentException - if the endian type is unknown

getByte

public byte getByte()

Get a byte, should be equal for all endians

Returns:

the byte value

getDouble

public double getDouble()

Get a double.

Returns:

the double value

getEndian

public int getEndian()

Gets the endian encoding.

Returns:

endian encoding

getInt

public int getInt()

Get an integer.

Returns:

interger

getInt

protected abstract int getInt(int index)

Get a 32-Bit integer

Parameters:

index - the index to get the value from

Returns:

the int value

getLong

public long getLong()

Get a long.

Returns:

long

getLong

protected abstract long getLong(int index)

Get a long value. This is not needed directly, but as a nice side-effect from GetDouble.

Parameters:

index - the index to get the value from

Returns:

the long value
