Uses of MethodExpression in jakarta.el

Methods in jakarta.el that return MethodExpression
Modifier and Type	Method	Description
`abstract MethodExpression`	ExpressionFactory.`createMethodExpression(ELContext context, String expression, Class<?> expectedReturnType, Class<?>[] expectedParamTypes)`	Parses an expression into a `MethodExpression` for later evaluation.

Uses of MethodExpression in jakarta.faces.component

Methods in jakarta.faces.component that return MethodExpression
Modifier and Type	Method	Description
`MethodExpression`	ActionSource2.`getActionExpression()`	Return the `MethodExpression` pointing at the application action to be invoked, if this `UIComponent` is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the `immediate` property.
`MethodExpression`	UICommand.`getActionExpression()`
`MethodExpression`	UIViewAction.`getActionExpression()`	Return the `MethodExpression` pointing at the application action to be invoked, if this `UIComponent` is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the `immediate` property.
`MethodExpression`	UIViewRoot.`getAfterPhaseListener()`	Return the `MethodExpression` that will be invoked after this view is rendered.
`MethodExpression`	UIViewRoot.`getBeforePhaseListener()`	Return the `MethodExpression` that will be invoked before this view is rendered.

Methods in jakarta.faces.component with parameters of type MethodExpression
Modifier and Type	Method	Description
`void`	ActionSource2.`setActionExpression(MethodExpression action)`	Set the `MethodExpression` pointing at the appication action to be invoked, if this `UIComponent` is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the `immediate` property.
`void`	UICommand.`setActionExpression(MethodExpression actionExpression)`
`void`	UIViewAction.`setActionExpression(MethodExpression actionExpression)`	Set the `MethodExpression` pointing at the appication action to be invoked, if this `UIComponent` is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the `immediate` property.
`void`	UIViewRoot.`setAfterPhaseListener(MethodExpression newAfterPhase)`	Allow an arbitrary method to be called for the "afterPhase" event as the UIViewRoot runs through its lifecycle.
`void`	UIViewRoot.`setBeforePhaseListener(MethodExpression newBeforePhase)`	Allow an arbitrary method to be called for the "beforePhase" event as the UIViewRoot runs through its lifecycle.

Uses of MethodExpression in jakarta.faces.event

Constructors in jakarta.faces.event with parameters of type MethodExpression
Constructor	Description
`MethodExpressionActionListener(MethodExpression methodExpressionOneArg)`	Construct a `ValueChangeListener` that contains a `MethodExpression`.
`MethodExpressionActionListener(MethodExpression methodExpressionOneArg, MethodExpression methodExpressionZeroArg)`
`MethodExpressionValueChangeListener(MethodExpression methodExpressionOneArg)`	Construct a `ValueChangeListener` that contains a `MethodExpression`.To accommodate method expression targets that take no arguments instead of taking a `ValueChangeEvent` argument, the implementation of this class must take the argument `methodExpressionOneArg`, extract its expression string, and create another `MethodExpression` whose expected param types match those of a zero argument method.
`MethodExpressionValueChangeListener(MethodExpression methodExpressionOneArg, MethodExpression methodExpressionZeroArg)`	Construct a `ValueChangeListener` that contains a `MethodExpression`.

Uses of MethodExpression in jakarta.faces.flow

Methods in jakarta.faces.flow that return MethodExpression
Modifier and Type	Method	Description
`abstract MethodExpression`	Flow.`getFinalizer()`	Return the `MethodExpression` that must be called by the runtime as the last thing that happens before exiting this flow.
`abstract MethodExpression`	Flow.`getInitializer()`	Return the `MethodExpression` that must be called by the runtime immediately after activating any `FlowScoped` beans declared for this flow.
`abstract MethodExpression`	MethodCallNode.`getMethodExpression()`	Return the `MethodExpression` to be invoked to when control passes to this node.

Uses of MethodExpression in jakarta.faces.flow.builder

Methods in jakarta.faces.flow.builder with parameters of type MethodExpression
Modifier and Type	Method	Description
`abstract MethodCallBuilder`	MethodCallBuilder.`expression(MethodExpression methodExpression)`	Set the method expression of this method call node.
`abstract FlowBuilder`	FlowBuilder.`finalizer(MethodExpression methodExpression)`	A MethodExpression that will be invoked when the flow is exited.
`abstract FlowBuilder`	FlowBuilder.`initializer(MethodExpression methodExpression)`	A MethodExpression that will be invoked when the flow is entered.

Uses of MethodExpression in jakarta.faces.validator

Constructors in jakarta.faces.validator with parameters of type MethodExpression
Constructor	Description
`MethodExpressionValidator(MethodExpression methodExpression)`	Construct a `Validator` that contains a `MethodExpression`.

Uses of MethodExpression in jakarta.faces.view.facelets

Methods in jakarta.faces.view.facelets that return MethodExpression
Modifier and Type	Method	Description
`abstract MethodExpression`	TagAttribute.`getMethodExpression(FaceletContext ctx, Class type, Class[] paramTypes)`	Create a MethodExpression, using this attribute's value as the expression String.
