Enum Constant Summary

Enum Constants

Enum Constant	Description
ASSIGNMENT_CONTEXT	Assignment context: potential poly-expressions are: method invocations, lambdas, reference expressions, conditional expressions and allocation expressions.
CASTING_CONTEXT	Casting context: potential poly-expressions are: lambdas and reference expressions Context induced by: CastExpression.
INVOCATION_CONTEXT	Invocation context: potential poly-expressions are: method invocations, lambdas, reference expressions, conditional expressions and allocation expressions.
VANILLA_CONTEXT	Vanilla context (string, numeric): potential poly-expressions are: NONE.

Method Summary

Modifier and Type	Method	Description
abstract boolean	definesTargetType()
static ExpressionContext	valueOf(String name)	Returns the enum constant of this class with the specified name.

Enum Constant Details

ASSIGNMENT_CONTEXT

public static final ExpressionContext ASSIGNMENT_CONTEXT

Assignment context: potential poly-expressions are: method invocations, lambdas, reference expressions, conditional expressions and allocation expressions. This is the only Java 7 context where target type influenced evaluation of some expression. Context induced by: ReturnStatement, ArrayInitializer, Assignment, FieldDeclaration and LocalDeclaration.

INVOCATION_CONTEXT

public static final ExpressionContext INVOCATION_CONTEXT

Invocation context: potential poly-expressions are: method invocations, lambdas, reference expressions, conditional expressions and allocation expressions. At this point, we don't distinguish between strict and loose invocation contexts - we may have to cross the bridge some day. Context induced by: AllocationExpression, QualifiedAllocationExpression, ExplicitConstructorCall, MessageSend CodeSnippetAllocationExpression and CodeSnippetMessageSend.

CASTING_CONTEXT

public static final ExpressionContext CASTING_CONTEXT

Casting context: potential poly-expressions are: lambdas and reference expressions Context induced by: CastExpression.

VANILLA_CONTEXT

public static final ExpressionContext VANILLA_CONTEXT

Vanilla context (string, numeric): potential poly-expressions are: NONE. This is the nonpoly context in which expressions get evaluated, unless they feature in one of the above contexts.

Method Details

values

public static ExpressionContext[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ExpressionContext valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

definesTargetType

public abstract boolean definesTargetType()
