Method Detail

compare0

public int compare0(long pageAddr,
                    int off,
                    IndexKey key)

Compares inlined and given value.

compare0 in class NullableInlineIndexKeyType<DoubleIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

key - Value that should be compare.

Returns:

-1, 0 or 1 if inlined value less, equal or greater than given respectively, NullableInlineIndexKeyType.CANT_BE_COMPARE if inlined part is not enough to compare, or NullableInlineIndexKeyType.COMPARE_UNSUPPORTED if given value can't be compared with inlined part at all.

put0

protected int put0(long pageAddr,
                   int off,
                   DoubleIndexKey key,
                   int maxSize)

Puts given value into inline index tree.

Specified by:

put0 in class NullableInlineIndexKeyType<DoubleIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

key - Value.

maxSize - Max size.

Returns:

Amount of bytes actually stored.

get0

protected DoubleIndexKey get0(long pageAddr,
                              int off)

Restores value from inline.

Specified by:

get0 in class NullableInlineIndexKeyType<DoubleIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

Returns:

Inline value.
