Constructor Detail

Range

public Range()

Default constructor defining a range starting on the first byte and with a maximum size, i.e. covering the whole entity.

Range

public Range(long size)

Constructor defining a range starting on the first byte and with the given size.

Parameters:

size - Size of the range in number of bytes.

Range

public Range(long index,
             long size)

Constructor.

Parameters:

index - Index from which to start the range

size - Size of the range in number of bytes.

Method Detail

equals

public boolean equals(Object object)

Overrides:

equals in class Object

getIndex

public long getIndex()

Returns the index from which to start the range. If the index is superior or equal to zero, the index will define the start of the range. If its value is -1L (-1), then it defines the end of the range. The default value is INDEX_FIRST (0), starting at the first byte.

Returns:

The index from which to start the range.

getSize

public long getSize()

Returns the size of the range in number of bytes. If the size is the maximum available from the index, then use the -1L constant.

Returns:

The size of the range in number of bytes.

isIncluded

public boolean isIncluded(long position,
                          long totalSize)

Indicates if the given index is included in the range.

Parameters:

position - The position to test.

totalSize -

Returns:

True if the given index is included in the range, false otherwise.

setIndex

public void setIndex(long index)

Sets the index from which to start the range. If the index is superior or equal to zero, the index will define the start of the range. If its value is -1L (-1), then it defines the end of the range. The default value is INDEX_FIRST (0), starting at the first byte

Parameters:

index - The index from which to start the range.

setSize

public void setSize(long size)

Sets the size of the range in number of bytes. If the size is the maximum available from the index, then use the -1L constant.

Parameters:

size - The size of the range in number of bytes.
