Constructor Detail

AsciiTransferType

public AsciiTransferType(int sizeBytes,
                         boolean scientificNotation)

Method Detail

write

public void write(double d,
                  java.nio.ByteBuffer buffer)

Description copied from class: TransferType

write the data to the buffer. The buffer's position should be incremented by sizeBytes.

Specified by:

write in class TransferType

Parameters:

d - the value to write.

buffer - the byte buffer positioned to receive sizeByte bytes.

read

public double read(java.nio.ByteBuffer buffer)

Description copied from class: TransferType

read the data from the buffer. The implementations will increment the buffer's position by sizeBytes.

Specified by:

read in class TransferType

Parameters:

buffer - the container for the transfer type.

Returns:

the value read

sizeBytes

public int sizeBytes()

Description copied from class: TransferType

return the number of bytes used by the transfer type.

Specified by:

sizeBytes in class TransferType

Returns:

the size of the type in bytes.

isAscii

public boolean isAscii()

Description copied from class: TransferType

return true if the transfer type uses ASCII-encodings to represent data. It's assumed in this case that trailing whitespace can be modified for readability.

Specified by:

isAscii in class TransferType

Returns:

true if the type is ASCII-based.

name

public java.lang.String name()

Description copied from class: TransferType

return a string identifying the TransferType.

Specified by:

name in class TransferType

Returns:

the name

getByName

public static TransferType getByName(java.lang.String name,
                                     java.util.Map<java.lang.String,java.lang.Object> properties)
