collectSubstitutes

public void collectSubstitutes(Scope scope,
 TypeBinding actualType,
 InferenceContext inferenceContext,
 int constraint)

Description copied from class: TypeBinding

Collect the substitutes into a map for certain type variables inside the receiver type e.g.

 Collection<T>.findSubstitute(T, Collection<List<X>>):   T --> List<X>

 Constraints:
   A << F   corresponds to:   F.collectSubstitutes(..., A, ..., CONSTRAINT_EXTENDS (1))
   A = F    corresponds to:   F.collectSubstitutes(..., A, ..., CONSTRAINT_EQUAL (0))
   A >> F   corresponds to:   F.collectSubstitutes(..., A, ..., CONSTRAINT_SUPER (2))
 

Overrides:

collectSubstitutes in class TypeBinding

 int idx)

Description copied from class: TypeBinding

Does this type mention any of the given type parameters, except the one at position 'idx'?

Overrides:

mentionsAny in class TypeBinding

computeUniqueKey

public char[] computeUniqueKey(boolean isLeaf)

Overrides:

computeUniqueKey in class Binding

constantPoolName

public char[] constantPoolName()

Description copied from class: TypeBinding

Answer the receiver's constant pool name. NOTE: This method should only be used during/after code gen. e.g. 'java/lang/Object'

Specified by:

constantPoolName in class TypeBinding

debugName

public String debugName()

Overrides:

debugName in class TypeBinding

annotatedDebugName

public String annotatedDebugName()

Overrides:

annotatedDebugName in class TypeBinding

dimensions

public int dimensions()

Overrides:

elementsType

public TypeBinding elementsType()

erasure

public TypeBinding erasure()

Overrides:

erasure in class TypeBinding

See Also:

• invalid reference

  org.eclipse.jdt.internal.compiler.lookup.TypeBinding#erasure()

upwardsProjection

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

Description copied from class: TypeBinding

Perform an upwards type projection as per JLS 4.10.5

Overrides:

upwardsProjection in class TypeBinding

Parameters:

scope - Relevant scope for evaluating type projection

mentionedTypeVariables - Filter for mentioned type variabled

Returns:

Upwards type projection of 'this', or null if downwards projection is undefined

downwardsProjection

public ArrayBinding downwardsProjection(Scope scope,
 TypeBinding[] mentionedTypeVariables)

Description copied from class: TypeBinding

Perform a downwards type projection as per JLS 4.10.5

Overrides:

downwardsProjection in class TypeBinding

Parameters:

scope - Relevant scope for evaluating type projection

mentionedTypeVariables - Filter for mentioned type variabled

Returns:

Downwards type projection of 'this', or null if downwards projection is undefined

environment

public LookupEnvironment environment()

genericTypeSignature

public char[] genericTypeSignature()

Description copied from class: TypeBinding

Answer the receiver classfile signature. Arrays and base types do not distinguish between signature() and constantPoolName(). NOTE: This method should only be used during/after code gen.

Overrides:

genericTypeSignature in class TypeBinding

getPackage

public PackageBinding getPackage()

Specified by:
