CaptureBinding

public CaptureBinding(CaptureBinding prototype)

Method Details

clone

public TypeBinding clone(TypeBinding enclosingType)

Description copied from class: TypeBinding

Virtual copy constructor: a copy is made of the receiver's entire instance state and then suitably parameterized by the arguments to the clone operation as seen fit by each type. Parameters may not make sense for every type in the hierarchy, in which case they are silently ignored. A type may choose to retain a copy of the prototype for reference.

Overrides:

clone in class TypeVariableBinding

computeUniqueKey

public char[] computeUniqueKey(boolean isLeaf)

Description copied from class: ReferenceBinding

p.X {} -> Lp/X;

Overrides:

computeUniqueKey in class TypeVariableBinding

debugName

public String debugName()

Overrides:

debugName in class TypeVariableBinding

See Also:

TypeBinding.debugName()

genericTypeSignature

public char[] genericTypeSignature()

Description copied from class: TypeVariableBinding

T::Ljava/util/Map;:Ljava/io/Serializable; T:LY

Overrides:

genericTypeSignature in class TypeVariableBinding

initializeBounds

public void initializeBounds(Scope scope,
 ParameterizedTypeBinding capturedParameterizedType)

Initialize capture bounds using substituted supertypes e.g. given X>, capture(X) = X, where capture extends X

upwardsProjection

public ReferenceBinding upwardsProjection(Scope scope,
 TypeBinding[] mentionedTypeVariables)

Description copied from class: ReferenceBinding

Perform an upwards type projection as per JLS 4.10.5

Overrides:

upwardsProjection in class TypeVariableBinding

Parameters:

scope - Relevant scope for evaluating type projection

mentionedTypeVariables - Filter for mentioned type variabled

upperBoundForProjection

public TypeBinding upperBoundForProjection()

isCapture

public boolean isCapture()

Description copied from class: TypeBinding

Returns true if the type is the capture of some wildcard

Overrides:

isCapture in class TypeBinding

See Also:

TypeBinding.isCapture()

isEquivalentTo

public boolean isEquivalentTo(TypeBinding otherType)

Description copied from class: TypeBinding

Returns true if a type is identical to another one, or for generic types, true if compared to its raw type.

Overrides:

isEquivalentTo in class TypeBinding

See Also:

TypeBinding.isEquivalentTo(TypeBinding)

isProperType

public boolean isProperType(boolean admitCapture18)

Description copied from class: TypeBinding

JLS8 Sect 18.1.1

Overrides:

isProperType in class TypeVariableBinding

Parameters:

admitCapture18 - request if CaptureBinding18 shuld be considered as a proper type. If unsure say 'true', only in Scope.greaterLowerBound(TypeBinding[], Scope, LookupEnvironment) CaptureBinding18 has to be excluded to prevent an NPE on a branch that heuristically tries to avoid inconsistent intersections.

readableName

public char[] readableName()

Description copied from class: ReferenceBinding

Answer the receiver's signature. NOTE: This method should only be used during/after code gen.

Overrides:

readableName in class TypeVariableBinding

See Also:

ReferenceBinding.readableName()

signableName

public char[] signableName()

Overrides:

signableName in class TypeBinding

shortReadableName

public char[] shortReadableName()

Overrides:

shortReadableName in class TypeVariableBinding

See Also:

ReferenceBinding.shortReadableName()

nullAnnotatedReadableName

public char[] nullAnnotatedReadableName(CompilerOptions options,
 boolean shortNames)

Description copied from class: TypeBinding

Answer a readable name (for error reporting) that includes nullness type annotations.

Overrides:

nullAnnotatedReadableName in class TypeVariableBinding

See Also:

TypeBinding.nullAnnotatedReadableName(CompilerOptions,boolean)

withoutToplevelNullAnnotation

public TypeBinding withoutToplevelNullAnnotation()

Description copied from class: TypeBinding

Return this type minus its toplevel null annotations. Any annotations on type arguments or bounds are retained.

Overrides:

withoutToplevelNullAnnotation in class TypeVariableBinding

setTypeAnnotations

public void setTypeAnnotations(AnnotationBinding[] annotations,
 boolean evalNullAnnotations)

Overrides:

setTypeAnnotations in class TypeVariableBinding

uncapture

public TypeBinding uncapture(Scope scope)

Description copied from class: TypeBinding

Perform capture "deconversion" on a given type

Overrides:

Description copied from class: ReferenceBinding

Perform a downwards type projection as per JLS 4.10.5

Overrides:

downwardsProjection in class TypeVariableBinding

Parameters:

scope - Relevant scope for evaluating type projection

mentionedTypeVariables - Filter for mentioned type variabled

toString

public String toString()

Overrides:
