Method Summary
abstract protected  ObjectcoerceFromString(String value)
     Coerces the value passed to InputElement.setText .

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString and InputElement.coerceFromString to convert between a string and your targeting type.

Moreover, when org.zkoss.mil.Textbox is called, it calls this method with value = null.

abstract protected  StringcoerceToString(Object value)
     Coerces the value passed to InputElement.setText .
protected  intgetConstraints()
    
public  StringgetInnerAttrs()
    
abstract protected  intgetInternalType()
     Internal type of this InputElement (ANY, EMAILADDR, NUMERIC, PHONENUMBER, URL, or DECIMAL).
public  intgetMaxlength()
     Returns the maxlength.
public  StringgetOuterAttrs()
    
public  StringgetRawText()
     Returns the text directly without checking whether any error message not yet fixed.
public  ObjectgetRawValue()
     Returns the raw value directly with checking whether any error message not yet fixed.
protected  ObjectgetTargetValue()
     Returns the value in the targeting type.
public  StringgetText()
     Returns the value in the String format.
public  StringgetType()
     Returns the type.

Method Detail
coerceFromString
abstract protected Object coerceFromString(String value) throws WrongValueException(Code)
Coerces the value passed to InputElement.setText .

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString and InputElement.coerceFromString to convert between a string and your targeting type.

Moreover, when org.zkoss.mil.Textbox is called, it calls this method with value = null. Derives shall handle this case properly.



coerceToString
abstract protected String coerceToString(Object value)(Code)
Coerces the value passed to InputElement.setText .

Default: convert null to an empty string.

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString and InputElement.coerceFromString to convert between a string and your targeting type.



getConstraints
protected int getConstraints()(Code)


getInnerAttrs
public String getInnerAttrs()(Code)


getInternalType
abstract protected int getInternalType()(Code)
Internal type of this InputElement (ANY, EMAILADDR, NUMERIC, PHONENUMBER, URL, or DECIMAL).


getMaxlength
public int getMaxlength()(Code)
Returns the maxlength.

Default: 32.



getOuterAttrs
public String getOuterAttrs()(Code)


getRawText
public String getRawText()(Code)
Returns the text directly without checking whether any error message not yet fixed.
See Also:   InputElement.getRawValue
See Also:   InputElement.getText


getRawValue
public Object getRawValue()(Code)
Returns the raw value directly with checking whether any error message not yet fixed.
See Also:   InputElement.getRawText
See Also:   InputElement.getText
See Also:   InputElement.setRawValue


getTargetValue
protected Object getTargetValue() throws WrongValueException(Code)
Returns the value in the targeting type.
exception:
  WrongValueException - if the user entered a wrong value
See Also:   InputElement.getText


getText
public String getText() throws WrongValueException(Code)
Returns the value in the String format. In most case, you shall use the setValue method instead, e.g., org.zkoss.mil.Textbox.getValue .

It invokes InputElement.coerceToString to convert the stored value into a string.
exception:
  WrongValueException - if user entered a wrong value



getType
public String getType()(Code)
Returns the type.

Default: text.



isReadonly
public boolean isReadonly()(Code)
Returns whether it is readonly.

Default: false.



newExtraCtrl
protected Object newExtraCtrl()(Code)


setMaxlength
public void setMaxlength(int maxlength)(Code)
Sets the maxlength.


setRawValue
public void setRawValue(Object value)(Code)
Sets the raw value directly. The caller must make sure the value is correct (or intend to be incorrect), because this method doesn't do any validation.

If you feel confusing with setValue, such as org.zkoss.mil.Textbox.setValue , it is usually better to use setValue instead. This method is reserved for developer that really want to set an 'illegal' value (such as an empty string to a textbox with no-empty contraint).

Like setValue, the result is returned back to the server by calling InputElement.getText .
See Also:   InputElement.getRawValue



setReadonly
public void setReadonly(boolean readonly)(Code)
Sets whether it is readonly.


setText
public void setText(String value) throws WrongValueException(Code)
Sets the value in the String format. In most case, you shall use the setValue method instead, e.g., org.zkoss.mil.Textbox.setValue .

It invokes InputElement.coerceFromString . Derives might override them for type conversion and special validation.
Parameters:
  value - the value; If null, it is considered as empty.



smartUpdateConstraints
protected void smartUpdateConstraints()(Code)
