Constructor Detail

GridH2ValueCacheObject

public GridH2ValueCacheObject(CacheObject obj,
                              CacheObjectValueContext valCtx)

Constructor.

Parameters:

obj - Object.

valCtx - Object value context.

Method Detail

getCacheObject

public CacheObject getCacheObject()

Returns:

Cache object.

valueContext

public CacheObjectValueContext valueContext()

Returns:

Value context.

getSQL

public String getSQL()

Overrides:

getSQL in class org.gridgain.internal.h2.value.Value

getSQL

public StringBuilder getSQL(StringBuilder sb)

Specified by:

getSQL in class org.gridgain.internal.h2.value.Value

getType

public org.gridgain.internal.h2.value.TypeInfo getType()

Specified by:

getType in class org.gridgain.internal.h2.value.Value

getValueType

public int getValueType()

Specified by:

getValueType in class org.gridgain.internal.h2.value.Value

getString

public String getString()

Specified by:

getString in class org.gridgain.internal.h2.value.Value

getBytes

public byte[] getBytes()

Overrides:

getBytes in class org.gridgain.internal.h2.value.Value

getBytesNoCopy

public byte[] getBytesNoCopy()

Overrides:

getBytesNoCopy in class org.gridgain.internal.h2.value.Value

getObject

public Object getObject()

Specified by:

getObject

public Object getObject(boolean cpy)

Parameters:

cpy - Copy flag.

Returns:

Value.

public void set(PreparedStatement prep,
                int parameterIndex)
         throws SQLException

Specified by:

set in class org.gridgain.internal.h2.value.Value

SQLException

compareTypeSafe

public int compareTypeSafe(org.gridgain.internal.h2.value.Value v,
                           org.gridgain.internal.h2.value.CompareMode mode)

Specified by:

compareTypeSafe in class org.gridgain.internal.h2.value.Value

useLegacyComparator

public void useLegacyComparator()

Stub GG-33962, GG-34893 (new comparator) workaround. Versions < 8.7.40 and < 8.8.11 are used incorrect comparator and a simple comparator change leads to the tree corruprion. Thus for "old" versions is used appropriate old comparator, we take into account that later all indexes will be rebuild and only one ver of comparator will be used.

legacyComparator

public boolean legacyComparator()

Returns:

true if legacy comparator is used, false otherwise.

                                                             boolean force)

Overrides:

convertPrecision in class org.gridgain.internal.h2.value.Value

getMemory

public int getMemory()

Overrides:

getMemory in class org.gridgain.internal.h2.value.Value
