Method Detail

compare0

protected int compare0(long pageAddr,
                       int off,
                       org.gridgain.internal.h2.value.Value v,
                       int type)

Compares inlined and given value.

compare0 in class AbstractInlineIndexColumn

Parameters:

pageAddr - Page address.

off - Offset.

v - Value that should be compare.

Returns:

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

put0

protected int put0(long pageAddr,
                   int off,
                   org.gridgain.internal.h2.value.Value val,
                   int maxSize)

Puts given value into inline index tree.

Specified by:

put0 in class AbstractInlineIndexColumn

Parameters:

pageAddr - Page address.

off - Offset.

val - Value.

maxSize - Max size.

Returns:

Amount of bytes actually stored.

get0

protected org.gridgain.internal.h2.value.Value get0(long pageAddr,
                                                    int off)

Restores value from inline.

Specified by:

get0 in class AbstractInlineIndexColumn

Parameters:

pageAddr - Page address.

off - Offset.

Returns:

Inline value or null if value can't be restored.

inlineSizeOf0

protected int inlineSizeOf0(org.gridgain.internal.h2.value.Value val)

Calculate size required to inline given value.

Specified by:

inlineSizeOf0 in class AbstractInlineIndexColumn

Parameters:
