All Implemented Interfaces:

AssignableValue, DataValue, NullableValue

Enclosing class:

EncodedSqlDecimal

public class EncodedSqlDecimal.AssignableDecimal
extends NullablePrimitive.NullableLong

Class which assigns a value to an EncodedSqlDecimal. Note that EncodedSqlDecimal cannot inherit from NullablePrimitive because EncodedSqlDecimal supports "NOT NULL" data and NullablePrimitive tags data as nullable.

Field Detail

parent

private EncodedSqlDecimal parent

longOverflow

private long longOverflow

The maximum LONG value that can be assigned to this decimal. No overflow check is performed when this value is set to Long.MAX_VALUE.

longScaleFactor

private long longScaleFactor

The scale factor applied to integers assigned to this decimal

Method Detail

setNull

public void setNull(boolean b)

Description copied from interface: NullableValue

Sets whether or not the value is null. Note that once a value has been set to null, its data should not be updated until the null state has been cleared with a call to setNull(false).

Specified by:

setNull in interface NullableValue

Overrides:

setNull in class NullablePrimitive

Parameters:

b - true to set a null value; false to indicate a non-null value

setNumber

protected void setNumber(Number number)

Description copied from class: NullablePrimitive

Assignment from abstract Number object.

Overrides:

setNumber in class NullablePrimitive.NullableLong

Parameters:

number - a new non-null value to be assigned

setLong

protected void setLong(long n)

Description copied from class: NullablePrimitive

Assignment from non-null long value.

Overrides:

setLong in class NullablePrimitive.NullableLong

Parameters:

n - long value to assign

assignFrom

public void assignFrom(Object obj)

Description copied from interface: AssignableValue

Assigns value from an Object.

Specified by:

assignFrom in interface AssignableValue

Overrides:

assignFrom in class NullablePrimitive.NullableLong

Parameters:

obj - value to assign, or null to set null
