Constructor Details

ValueBytesBase

ValueBytesBase(byte[] value)

Method Details

getBytes

public final byte[] getBytes()

Overrides:

getBytes in class Value

getBytesNoCopy

public final byte[] getBytesNoCopy()

Overrides:

getBytesNoCopy in class Value

compareTypeSafe

public final int compareTypeSafe(Value v,
 CompareMode mode,
 CastDataProvider provider)

Description copied from class: Value

Compare this value against another value given that the values are of the same data type.

Specified by:

compareTypeSafe in class Value

Parameters:

v - the other value

mode - the compare mode

provider - the cast information provider

Returns:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

getSQL

public StringBuilder getSQL(StringBuilder builder,
 int sqlFlags)

Description copied from interface: HasSQL

Appends the SQL statement of this object to the specified builder.

Parameters:

builder - string builder

sqlFlags - formatting flags

Returns:

the specified string builder

hashCode

public final int hashCode()

Specified by:

hashCode in class Value

getMemory

public int getMemory()

Description copied from class: Value

Get the memory used by this object.

Overrides:

getMemory in class Value

Returns:

the memory used in bytes

equals

public final boolean equals(Object other)

Description copied from class: Value

Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.

Specified by:

equals in class Value

Parameters:

other - the other value

Returns:

true if they are equal
