fromString

public java.math.BigDecimal fromString(java.lang.String string)

areEqual

public boolean areEqual(java.math.BigDecimal one,
               java.math.BigDecimal another)

Description copied from class: AbstractTypeDescriptor

Determine if two instances are equal

Specified by:

areEqual in interface JavaTypeDescriptor<java.math.BigDecimal>

Overrides:

areEqual in class AbstractTypeDescriptor<java.math.BigDecimal>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(java.math.BigDecimal value)

Description copied from class: AbstractTypeDescriptor

Extract a proper hash code for this value.

Specified by:

extractHashCode in interface JavaTypeDescriptor<java.math.BigDecimal>

Overrides:

extractHashCode in class AbstractTypeDescriptor<java.math.BigDecimal>

Parameters:

value - The value for which to extract a hash code.

Returns:

The extracted hash code.

unwrap

public <X> X unwrap(java.math.BigDecimal value,
           java.lang.Class<X> type,
           WrapperOptions options)

Description copied from interface: JavaTypeDescriptor

Unwrap an instance of our handled Java type into the requested type.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap the Integer value as a Long we would return something like Long.valueOf( value.longValue() ).

Intended use is during PreparedStatement binding.

Type Parameters:

X - The conversion type.

Parameters:

value - The value to unwrap

type - The type as which to unwrap

options - The options

Returns:

The unwrapped value.

wrap

public <X> java.math.BigDecimal wrap(X value,
                            WrapperOptions options)

Description copied from interface: JavaTypeDescriptor

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Type Parameters:

X - The conversion type.

Parameters:

value - The value to wrap.

options - The options

Returns:

The wrapped value.
