Method Detail

formatValue

public abstract String formatValue(T v)

Description copied from interface: ScalarType

Convert the type into a string representation.

Reciprocal of parse().

parse

public abstract T parse(String value)

Description copied from interface: ScalarType

Convert the string value to the appropriate java object.

Mostly used to support CSV, JSON and XML parsing.

Reciprocal of formatValue().

convertFromDbString

public abstract T convertFromDbString(String dbValue)

convertToDbString

public abstract String convertToDbString(T beanValue)

bind

public void bind(DataBind b,
        T value)
          throws SQLException

Description copied from interface: ScalarType

Convert (if necessary) and bind the value to the preparedStatement.

value may need to be converted from the logical bean property type to the JDBC type.

Throws:

SQLException

read

public T read(DataReader dataReader)
       throws SQLException

Description copied from interface: ScalarType

Read the value from the resultSet and convert if necessary to the logical bean property value.

Throws:

SQLException

toBeanType

public T toBeanType(Object value)

Description copied from interface: ScalarType

Convert the value as necessary to the logical Bean type.

The type as per the bean property.

This is used to automatically convert id values (typically from a string to a int, long or UUID).

toJdbcType

public Object toJdbcType(Object value)

Description copied from interface: ScalarType

Convert the value as necessary to the JDBC type.

Note that this should also match the type as per the getJdbcType() method.

This is typically used when the matching type is used in a where clause and we use this to ensure it is an appropriate jdbc type.

parseDateTime

public T parseDateTime(long systemTimeMillis)

Description copied from interface: ScalarType

Convert the systemTimeMillis into the appropriate java object.

For non dateTime types this will throw an exception.

isDateTimeCapable

public boolean isDateTimeCapable()

Description copied from interface: ScalarType

Return true if the type can accept long systemTimeMillis input.

This is used to determine if is is sensible to use the ScalarType.parseDateTime(long) method.

This includes the Date, Calendar, sql Date, Time, Timestamp, JODA types as well as Long, BigDecimal and String (although it generally is not expected to parse systemTimeMillis to a String or BigDecimal).

format

public String format(Object v)

Description copied from interface: ScalarType

Convert the type into a string representation.

This assumes the value is of the correct type.

This is so that ScalarType also implements the StringFormatter interface.

Specified by:

format in interface StringFormatter

Specified by:

format in interface ScalarType<T>

Overrides:

format in class ScalarTypeBase<T>

jsonFromString

public T jsonFromString(String value,
               JsonValueAdapter ctx)

Specified by:

jsonFromString in interface ScalarType<T>

Overrides:

jsonFromString in class ScalarTypeBase<T>

toJsonString

public String toJsonString(Object value,
                  JsonValueAdapter ctx)

jsonWrite

public void jsonWrite(WriteJsonBuffer buffer,
             T value,
             JsonValueAdapter ctx)

Specified by:

jsonWrite in interface ScalarType<T>

Overrides:

jsonWrite in class ScalarTypeBase<T>

readData

public Object readData(DataInput dataInput)
                throws IOException

Throws:

IOException

writeData

public void writeData(DataOutput dataOutput,
             Object v)
               throws IOException

Throws:

IOException
