public class ShortBufferWrapper
extends NumberBufferWrapper

This buffer wrapper reads one or more short values. Note that fetching a value by index reads a single value only rather than loading the whole buffer.

                  BinaryChannel binaryChannel)

Method Detail

getShortBuffer

protected final java.nio.ShortBuffer getShortBuffer()
                                             throws java.io.IOException

Throws:

java.io.IOException

getValue

public final short getValue()
                     throws java.io.IOException

Loads all values into the buffer and returns the first one. The value is cached internally until reset() is called.

Throws:

java.io.IOException

getValues

public final short[] getValues()
                        throws java.io.IOException

Loads all values into the buffer and returns them as an array. The array is cached internally until reset() is called.

Throws:

java.io.IOException

getValue

public final int getValue(int index)
                   throws java.io.IOException

Returns the value at the given index. Note that this method is tuned to load only a single value at the given index rather than loading the whole buffer. Thus fetching all values by index may be inefficient. Consider to use getValues() instead.

Throws:

java.io.IOException

getDoubleValue

public double getDoubleValue()
                      throws java.io.IOException

Specified by:

getDoubleValue in class NumberBufferWrapper

Throws:

java.io.IOException

getDoubleValue

public double getDoubleValue(int index)
                      throws java.io.IOException

Specified by:

getDoubleValue in class NumberBufferWrapper

Throws:

java.io.IOException

createSingleValueBufferWrapper

protected NumberBufferWrapper createSingleValueBufferWrapper()

Specified by:

createSingleValueBufferWrapper in class NumberBufferWrapper

reset

public void reset()

Description copied from class: ByteBufferWrapper

Clears the internal cache and forces the data to be re-read again on the next access.

Specified by:

reset in interface Resettable

Overrides:
