Method Detail

compare0

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

Compares inlined and given value.

Specified by:

compare0 in class NullableInlineIndexKeyType<UuidIndexKey>

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,
                   UuidIndexKey key,
                   int maxSize)

Puts given value into inline index tree.

Specified by:

put0 in class NullableInlineIndexKeyType<UuidIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

key - Value.

maxSize - Max size.

Returns:

Amount of bytes actually stored.

get0

protected UuidIndexKey get0(long pageAddr,
                            int off)

Restores value from inline.

Specified by:

get0 in class NullableInlineIndexKeyType<UuidIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

Returns:

Inline value.

inlineSize0

protected int inlineSize0(UuidIndexKey val)

Return inlined size for specified key.

Specified by:

inlineSize0 in class NullableInlineIndexKeyType<UuidIndexKey>
