方法详细资料

toString

public String toString(BigInteger value)

fromString

public BigInteger fromString(String string)

extractHashCode

public int extractHashCode(BigInteger value)

从接口复制的说明: JavaTypeDescriptor

Extract a proper hash code for this value.

指定者:

extractHashCode 在接口中 JavaTypeDescriptor<BigInteger>

覆盖:

extractHashCode 在类中 AbstractTypeDescriptor<BigInteger>

参数:

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

返回:

The extracted hash code.

areEqual

public boolean areEqual(BigInteger one,
                        BigInteger another)

从接口复制的说明: JavaTypeDescriptor

Determine if two instances are equal

指定者:

areEqual 在接口中 JavaTypeDescriptor<BigInteger>

覆盖:

areEqual 在类中 AbstractTypeDescriptor<BigInteger>

参数:

one - One instance

another - The other instance

返回:

True if the two are considered equal; false otherwise.

unwrap

public <X> X unwrap(BigInteger value,
                    Class<X> type,
                    WrapperOptions options)

从接口复制的说明: 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.

类型参数:

X - The conversion type.

参数:

value - The value to unwrap

type - The type as which to unwrap

options - The options

返回:

The unwrapped value.

wrap

public <X> BigInteger wrap(X value,
                           WrapperOptions options)

从接口复制的说明: JavaTypeDescriptor

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

类型参数:

X - The conversion type.

参数:

value - The value to wrap.

options - The options

返回:

The wrapped value.
