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 JavaStatementBuilder 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:

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

complete

public JavaStatement 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 JavaReturnStatement completeAsReturn()

Description copied from class: JavaStatementBuilder

Complete this statement builder by returning all expressions.

Specified by:

completeAsReturn in class JavaStatementBuilder

completeAsExpressionStatement
