常量字段

BIGINTEGER_ID

public static final String BIGINTEGER_ID

The message identifier of the FacesMessage to be created if the conversion to BigInteger fails. The message format string for this message may optionally include the following placeholders:

  • {0} replaced by the unconverted value.
  • {1} replaced by an example value.
  • {2} replaced by a String whose value is the label of the input component that produced this message.

常量字段

STRING_ID

public static final String STRING_ID

The message identifier of the FacesMessage to be created if the conversion of the BigInteger value to String fails. The message format string for this message may optionally include the following placeholders:

  • {0} relaced by the unconverted value.
  • {1} replaced by a String whose value is the label of the input component that produced this message.

方法详细信息

getAsObject

public Object getAsObject(FacesContext context,
                          UIComponent component,
                          String value)
Description copied from interface: Converter

Convert the specified string value, which is associated with the specified UIComponent, into a model data object that is appropriate for being stored during the Apply Request Values phase of the request processing lifecycle.

规范说明:
getAsObject in interface Converter
参数:
context - FacesContext for the request being processed
component - UIComponent with which this model object value is associated
value - String value to be converted (may be null)
返回:
null if the value to convert is null, otherwise the result of the conversion
抛出异常:
ConverterException - if conversion cannot be successfully performed
NullPointerException - if context or component is null

getAsString

public String getAsString(FacesContext context,
                          UIComponent component,
                          Object value)
Description copied from interface: Converter

Convert the specified model object value, which is associated with the specified UIComponent, into a String that is suitable for being included in the response generated during the Render Response phase of the request processing lifeycle.

规范说明:
getAsString in interface Converter
参数:
context - FacesContext for the request being processed
component - UIComponent with which this model object value is associated
value - Model object value to be converted (may be null)
返回:
a zero-length String if value is null, otherwise the result of the conversion
抛出异常:
ConverterException - if conversion cannot be successfully performed
NullPointerException - if context or component is null
