Method Details

getExpressionType

public JavaType getExpressionType()

Description copied from class: JavaStatementBuilder

Get the type of the last expression of this builder, or the least common supertype of all expressions in different branches of this builder.

Specified by:

getExpressionType in class JavaStatementBuilder

mapExpression

public JavaIfThenElseBuilder mapExpression(Function<JavaExpression,? extends JavaStatementBuilder> mapper)

Description copied from class: JavaStatementBuilder

Map all expressions contained in this builder to a new builder, and append the result. This will flatten Java block statements.

Specified by:

mapExpression in class JavaStatementBuilder

then

public JavaStatementBuilder then(JavaStatementBuilder after,
 BiFunction<JavaExpression,JavaExpression,JavaStatementBuilder> combineExpressions,
 JavaScope scope)

Description copied from class: JavaStatementBuilder

Append another statement builder to this one, and combine this expression with the other using the given operation.

Specified by:

then in class JavaStatementBuilder

complete

public JavaIfThenElseStatement complete(Function<JavaExpression,JavaStatement> completer)

Description copied from class: JavaStatementBuilder

Complete this statement builder by mapping all expressions to a statement.

Specified by:

complete in class JavaStatementBuilder

completeAsReturn

public JavaBlock completeAsReturn()

Description copied from class: JavaStatementBuilder

Complete this statement builder by returning all expressions.

Specified by:

completeAsReturn in class JavaStatementBuilder

completeAsExpressionStatement

public JavaIfThenElseStatement completeAsExpressionStatement()

Description copied from class: JavaStatementBuilder

Complete this statement builder by ending all expressions with a semicolon.

Specified by:

completeAsExpressionStatement in class JavaStatementBuilder

completeAsAssignment

public JavaIfThenElseStatement completeAsAssignment(GeneratedIdentifier variableId)

Description copied from class: JavaStatementBuilder

Specified by:

declareAsVariable in class JavaStatementBuilder

collapseToSingleExpression

public JavaStatementBuilder collapseToSingleExpression(JavaScope scope)

Description copied from class: JavaStatementBuilder

If this statement builder ends with multiple branches, assign all expressions to a new variable and return a new builder ending with that variable. If this statement builder does not end in multiple branches, return itself unmodified.

Specified by:

collapseToSingleExpression in class JavaStatementBuilder

toLambdaBody

public JavaLambdaBody toLambdaBody()
