StringValueFactory

public StringValueFactory(PropertySet pset)

方法详细资料

setPropertySet

public void setPropertySet(PropertySet pset)

指定者:

setPropertySet 在接口中 ValueFactory<String>

createFromDate

public String createFromDate(InternalDate idate)

Create a string from InternalDate. The fields are formatted in a YYYY-mm-dd format.

指定者:

createFromDate 在接口中 ValueFactory<String>

参数:

idate - InternalDate

返回:

string

createFromTime

public String createFromTime(InternalTime it)

Create a string from InternalTime. The fields are formatted in a HH:MM:SS[.nnnnnnnnn] format.

指定者:

createFromTime 在接口中 ValueFactory<String>

参数:

it - InternalTime

返回:

string

createFromTimestamp

public String createFromTimestamp(InternalTimestamp its)

Create a string from time fields. The fields are formatted by concatenating the result of createFromDate(InternalDate) and createFromTime(InternalTime).

指定者:

createFromTimestamp 在接口中 ValueFactory<String>

参数:

its - InternalTimestamp

返回:

string

createFromDatetime

public String createFromDatetime(InternalTimestamp its)

Create a string from time fields. The fields are formatted by concatenating the result of createFromDate(InternalDate) and createFromTime(InternalTime).

指定者:

createFromDatetime 在接口中 ValueFactory<String>

参数:

its - InternalTimestamp

返回:

string

createFromLong

public String createFromLong(long l)

指定者:

createFromLong 在接口中 ValueFactory<String>

createFromBigInteger

public String createFromBigInteger(BigInteger i)

指定者:

createFromBigInteger 在接口中 ValueFactory<String>

createFromDouble

public String createFromDouble(double d)

指定者:

createFromDouble 在接口中 ValueFactory<String>

createFromBigDecimal

public String createFromBigDecimal(BigDecimal d)

指定者:

createFromBigDecimal 在接口中 ValueFactory<String>

createFromBytes

public String createFromBytes(byte[] bytes,
                              int offset,
                              int length,
                              Field f)

Interpret the given byte array as a string. This value factory needs to know the encoding to interpret the string. The default (null) will interpret the byte array using the platform encoding.

指定者:

createFromBytes 在接口中 ValueFactory<String>

参数:

bytes - byte array

offset - offset

length - data length in bytes

f - field

返回:

string

createFromBit

public String createFromBit(byte[] bytes,
                            int offset,
                            int length)

指定者:

createFromBit 在接口中 ValueFactory<String>

createFromYear

public String createFromYear(long l)

指定者:

createFromYear 在接口中 ValueFactory<String>

createFromNull

public String createFromNull()

从接口复制的说明: ValueFactory

Create result value from intermediate null value.

指定者:

createFromNull 在接口中 ValueFactory<String>

返回:

T object

getTargetTypeName

public String getTargetTypeName()

从接口复制的说明: ValueFactory

Get the actual class name of T parameter.

指定者:

getTargetTypeName 在接口中 ValueFactory<String>

返回:

class name
