Method Detail

put0

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

Puts given value into inline index tree.

Specified by:

put0 in class NullableInlineIndexKeyType<StringIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

key - Value.

maxSize - Max size.

Returns:

Amount of bytes actually stored.

get0

protected StringIndexKey get0(long pageAddr,
                              int off)

Restores value from inline.

Specified by:

get0 in class NullableInlineIndexKeyType<StringIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

Returns:

Inline value.

compare0

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

Compares inlined and given value.

Specified by:

compare0 in class NullableInlineIndexKeyType<StringIndexKey>

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.

inlineSize0

protected int inlineSize0(StringIndexKey key)

Return inlined size for specified key.

Specified by:

inlineSize0 in class NullableInlineIndexKeyType<StringIndexKey>

inlinedFullValue

public boolean inlinedFullValue(long pageAddr,
                                int off,
                                int maxSize)

Whether inline contains full index key.

Specified by:

inlinedFullValue in interface InlineIndexKeyType

Overrides:

inlinedFullValue in class NullableInlineIndexKeyType<StringIndexKey>

Parameters:

pageAddr - Page address.

off - Offset.

maxSize - Remaining inlined buffer size (max available bytes to read for the current row).

Returns:

true if inline contains full index key. Can be false for truncated variable length types.
