Constructor	Description
FunctionalSwitchExpressionScanner(BiFunction<ExpressionTree,P1,R1> switchValueExpressionFunc, BiFunction<@Nullable R1,@Nullable R1,R1> combineResultFunc)	Creates a SwitchExpressionScanner.FunctionalSwitchExpressionScanner that uses the given functions.

Method Summary

Modifier and Type	Method	Description
protected R1	combineResults(@Nullable R1 r1, @Nullable R1 r2)	This method combines the result of two calls to SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object) or null and the result of one call to SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object).
protected R1	visitSwitchResultExpression(ExpressionTree resultExpressionTree, P1 p1)	This method is called for each result expression of the switch expression passed in SwitchExpressionScanner.scanSwitchExpression(Tree, Object).

Constructor Details

FunctionalSwitchExpressionScanner

public FunctionalSwitchExpressionScanner(BiFunction<ExpressionTree,P1,R1> switchValueExpressionFunc,
 BiFunction<@Nullable R1,@Nullable R1,R1> combineResultFunc)

Creates a SwitchExpressionScanner.FunctionalSwitchExpressionScanner that uses the given functions.

Parameters:

switchValueExpressionFunc - the function called on each switch result expression

combineResultFunc - the function used to combine the result of multiple calls to switchValueExpressionFunc

Method Details

visitSwitchResultExpression

protected R1 visitSwitchResultExpression(ExpressionTree resultExpressionTree,
 P1 p1)

Description copied from class: SwitchExpressionScanner

This method is called for each result expression of the switch expression passed in SwitchExpressionScanner.scanSwitchExpression(Tree, Object).

Specified by:

visitSwitchResultExpression in class SwitchExpressionScanner<R1,P1>

Parameters:

resultExpressionTree - a result expression of the switch expression currently being scanned

p1 - a parameter

Returns:

the result of visiting the result expression

combineResults

protected R1 combineResults(@Nullable R1 r1,
 @Nullable R1 r2)

Description copied from class: SwitchExpressionScanner

This method combines the result of two calls to SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object) or null and the result of one call to SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object).

Specified by:

combineResults in class SwitchExpressionScanner<R1,P1>

Parameters:

r1 - a possibly null result returned by SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object)

r2 - a possibly null result returned by SwitchExpressionScanner.visitSwitchResultExpression(ExpressionTree, Object)

Returns:

the combination of r1 and r2
