Method Details

getExpressionString
Description copied from class:ValueBindingReturn the (possibly
null) expression String, including the delimiters, from which thisValueBindingwas built.- Overrides:
getExpressionStringin classValueBinding- Returns:
- the expression string
-
getType
Description copied from class:ValueBindingReturn the type of the property represented by this
ValueBinding, relative to the specifiedFacesContext.- Specified by:
getTypein classValueBinding- Parameters:
context-FacesContextfor the current request- Returns:
- the Java type of this expression
- Throws:
EvaluationException- if an exception is thrown while getting the description of the property (the thrown exception must be included as thecauseproperty of this exception)PropertyNotFoundException- if a specified property name does not exist
-
getValue
Description copied from class:ValueBindingReturn the value of the property represented by this
ValueBinding, relative to the specifiedFacesContext.- Specified by:
getValuein classValueBinding- Parameters:
context-FacesContextfor the current request- Returns:
- the value of this expression
- Throws:
EvaluationException- if an exception is thrown while getting the value (the thrown exception must be included as thecauseproperty of this exception)PropertyNotFoundException- if a specified property name does not exist, or is not readable
-
isReadOnly
public boolean isReadOnly(FacesContext context) throws EvaluationException, PropertyNotFoundExceptionDescription copied from class:ValueBindingReturn
trueif the specified property of the specified property is known to be immutable; otherwise, returnfalse.- Specified by:
isReadOnlyin classValueBinding- Parameters:
context-FacesContextfor the current request- Returns:
- whether or not this expression is read only
- Throws:
EvaluationException- if an exception is thrown while getting the description of the property (the thrown exception must be included as thecauseproperty of this exception)PropertyNotFoundException- if a specified property name does not exist
-
setValue
public void setValue(FacesContext context, Object value) throws EvaluationException, PropertyNotFoundExceptionDescription copied from class:ValueBindingSet the value of the property represented by this
ValueBinding, relative to the specifiedFacesContext.- Specified by:
setValuein classValueBinding- Parameters:
context-FacesContextfor the current requestvalue- The new value to be set- Throws:
EvaluationException- if an exception is thrown while setting the value (the thrown exception must be included as thecauseproperty of this exception)PropertyNotFoundException- if a specified property name does not exist, or is not writeable
-
isTransient
public boolean isTransient()Description copied from interface:StateHolderIf true, the Object implementing this interface must not participate in state saving or restoring.
- Specified by:
isTransientin interfaceStateHolder- Returns:
trueif transient,falseotherwise.
-
setTransient
public void setTransient(boolean tranzient)Description copied from interface:StateHolderDenotes whether or not the Object implementing this interface must or must not participate in state saving or restoring.
- Specified by:
setTransientin interfaceStateHolder- Parameters:
tranzient- boolean passtrueif this Object will not participate in state saving or restoring, otherwise passfalse.
-
saveState
Description copied from interface:StateHolderGets the state of the instance as a
SerializableObject.If the class that implements this interface has references to instances that implement StateHolder (such as a
UIComponentwith event handlers, validators, etc.) this method must call theStateHolder.saveState(jakarta.faces.context.FacesContext)method on all those instances as well. This method must not save the state of children and facets. That is done via theStateManagerThis method must not alter the state of the implementing object. In other words, after executing this code:
Object state = component.saveState(facesContext);componentshould be the same as before executing it.The return from this method must be
Serializable- Specified by:
saveStatein interfaceStateHolder- Parameters:
context- the Faces context.- Returns:
- the saved state.
-
restoreState
Description copied from interface:StateHolderPerform any processing required to restore the state from the entries in the state Object.
If the class that implements this interface has references to instances that also implement StateHolder (such as a
UIComponentwith event handlers, validators, etc.) this method must call theStateHolder.restoreState(jakarta.faces.context.FacesContext, java.lang.Object)method on all those instances as well.If the
stateargument isnull, take no action and return.- Specified by:
restoreStatein interfaceStateHolder- Parameters:
context- the Faces context.state- the state.
