Method Detail

type

int type()

Returns type of inlined column.

Returns:

Integer code of the column's value type.

See Also:

Value

size

short size()

Size required to inline value of type type().

Returns:

Amount of bytes required for fixed-size types or -1 for types with variable length.

fullSize

int fullSize(long pageAddr,
             int off)

Actual size of inline value. It returns size() + 1 for values with fixed size and amount of written bytes for values with variable length.

Parameters:

pageAddr - Page address.

off - Offset.

Returns:

Returns actual size of inlined value.

compare

int compare(long pageAddr,
            int off,
            int maxSize,
            org.gridgain.internal.h2.value.Value v,
            Comparator<org.gridgain.internal.h2.value.Value> comp)

Compares inlined and given value.

Parameters:

pageAddr - Page address.

off - Offset.

maxSize - Max size.

v - Value that should be compare.

comp - Comparator.

Returns:

-1, 0 or 1 if inlined value less, equal or greater than given respectively, or -2 if inlined part is not enough to compare.

inlineSizeOf

int inlineSizeOf(org.gridgain.internal.h2.value.Value val)

Calculate size required to inline given value.

Parameters:

val - Value to calculate inline size.

Returns:

Calculated inline size.

put

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

Puts given value into inline index tree.

Parameters:

pageAddr - Page address.

off - Offset.

val - Value.

maxSize - Max size.

Returns:

Amount of bytes actually stored.

columnName

String columnName()

Returns name of the inlined column.

Returns:

Name of the column.

columnIndex

int columnIndex()

Returns index of the inlined column.

Returns:

Index of the column.

columnSql

String columnSql()

Returns sql representation of the inlined column.

Returns:

Sql representation of the column.
