public MethodCallBuilder()

Method Detail

expression

public abstract MethodCallBuilder expression(MethodExpression methodExpression)

Set the method expression of this method call node. The method signature of the argument methodExpression must match the number and type of the parameters passed in the parameters(java.util.List<javax.faces.flow.Parameter>) method.

Parameters:

methodExpression - The MethodExpression to invoke.

Returns:

the builder instance

Throws:

java.lang.NullPointerException - if any of the parameters are null

Since:

2.2

expression

public abstract MethodCallBuilder expression(java.lang.String methodExpression)

Set the method expression of this method call node. The method signature of the argument methodExpression must match the number and type of the parameters passed in the parameters(java.util.List<javax.faces.flow.Parameter>) method.

Parameters:

methodExpression - The MethodExpression String to invoke.

Returns:

the builder instance

Throws:

java.lang.NullPointerException - if any of the parameters are null

Since:

2.2

expression

parameters

public abstract MethodCallBuilder parameters(java.util.List<Parameter> parameters)

Set the parameters of the method call node.

Parameters:

parameters - the parameters to pass to the method when it is invoked.

Returns:

the builder instance

java.lang.NullPointerException - if any of the parameters are null

Since:

2.2

defaultOutcome

public abstract MethodCallBuilder defaultOutcome(java.lang.String outcome)

If the method is a void method, or the method returns null, this can be used to specify what value should be passed to runtime when the method returns.

Parameters:

outcome - A ValueExpression String representing the default outcome, only used if the method is a void method or returns null.

Returns:

the builder instance

Throws:

java.lang.NullPointerException - if any of the parameters are null

Since:

2.2

defaultOutcome

public abstract MethodCallBuilder defaultOutcome(ValueExpression outcome)

If the method is a void method, or the method returns null, this can be used to specify what value should be passed to runtime when the method returns.

Parameters:

outcome - A ValueExpression representing the default outcome, only used if the method is a void method or returns null.

markAsStartNode

public abstract MethodCallBuilder markAsStartNode()

Description copied from interface: NodeBuilder

Mark this node as the start node in the flow. Any other node that had been marked as the start node will no longer be the start node.

Specified by:

markAsStartNode in interface NodeBuilder

Returns:

the builder instance
