All Implemented Interfaces:

IDestructable

public class NdComplexTypeSignature
extends NdTypeSignature

Represents a type signature that is anything other than a trivial reference to a concrete type. If a type reference includes annotations, generic arguments, wildcards, or is a type variable, this object represents it.

Arrays are encoded in a special way. The RAW_TYPE points to a sentinel type called '[' and the first type argument holds the array type.

Method Detail

getRawType

public NdTypeId getRawType()

Description copied from class: NdTypeSignature

Returns the raw version of this type, if one exists. That is, the version of this type without any generic arguments or annotations, which the java runtime sees. Returns null of this signature doesn't have a raw type, for example if it is a type variable.

Specified by:

getRawType in class NdTypeSignature

setVariableIdentifier

public void setVariableIdentifier(char[] variableIdentifier)

getVariableIdentifier

public IString getVariableIdentifier()

If this type is a type variable, this returns the variable's identifier.

setRawType

public void setRawType(NdTypeId rawType)

setGenericDeclaringType

public void setGenericDeclaringType(NdComplexTypeSignature enclosingType)

getGenericDeclaringType

public NdComplexTypeSignature getGenericDeclaringType()

Returns the declaring type (as reported by the type's generic signature). Not to be confused with the declaring type as stored in the class file. That is stored in NdType.getDeclaringType(). Any class that is nested inside another class with generic arguments will have one of these. Classes nested inside non-generic classes won't have one of these, and neither will non-nested classes.

getTypeArguments

public java.util.List<NdTypeArgument> getTypeArguments()

Description copied from class: NdTypeSignature

Returns the type arguments for this type signature, if any. Returns the empty list if none.

Specified by:

getTypeArguments in class NdTypeSignature

getArrayDimensionType

public NdTypeSignature getArrayDimensionType()

Description copied from class: NdTypeSignature

If the receiver is an array type, it returns the signature of the array's next dimension. Returns null if this is not an array type.

Specified by:

getArrayDimensionType in class NdTypeSignature

getSignature

public void getSignature(CharArrayBuffer result,
                         boolean includeTrailingSemicolon)

Specified by:

getSignature in class NdTypeSignature

isTypeVariable

public boolean isTypeVariable()

Specified by:

isTypeVariable in class NdTypeSignature

getDeclaringTypeChain

public java.util.List<NdTypeSignature> getDeclaringTypeChain()

Description copied from class: NdTypeSignature

Returns the chain of declaring generic types. The first element in the chain is a top-level type and the receiver is the last element in the chain.

Specified by:

getDeclaringTypeChain in class NdTypeSignature

isArrayType

public boolean isArrayType()

Description copied from class: NdTypeSignature

Returns true iff this is an array type signature (ie: that getArrayDimensionType() will return a non-null answer). Note that this only returns true for the type signature that holds the reference to the array dimension type. The raw type for that signature will return false, even though it has a field descriptor starting with '['.

In other words:

 NdVariable someVariable = getSomeVariableWithAnArrayType()
 System.out.println(someVariable.getType().isArrayType()); // true
 System.out.println(someVariable.getType().getRawType().isArrayType()); // false
 

Specified by:

isArrayType in class NdTypeSignature
