public abstract static class TypeDescription.Generic.LazyProjection extends TypeDescription.Generic.AbstractBase
A lazy projection of a generic type. Such projections allow to only read generic type information in case it is required. This is meaningful as the Java virtual needs to process generic type information which requires extra resources. Also, this allows the extraction of non-generic type information even if the generic type information is invalid.

Method Detail
-
resolve
protected abstract TypeDescription.Generic resolve()
Resolves the actual generic type.- Returns:
- An actual description of the represented generic type.
-
getSort
public TypeDefinition.Sort getSort()
Returns the sort of the generic type this instance represents.- Returns:
- The sort of the generic type.
-
getDeclaredFields
public FieldList<FieldDescription.InGenericShape> getDeclaredFields()
Returns the fields that this type declares. A super type is only defined for non-generic types (TypeDefinition.Sort.NON_GENERIC
), parameterized types (TypeDefinition.Sort.PARAMETERIZED
) or generic array types (TypeDefinition.Sort.GENERIC_ARRAY
) types. Generic array types never define fields and the returned list is always empty for such types.- Returns:
- The fields that this type declares. A super type is only defined for non-generic types (
TypeDefinition.Sort.NON_GENERIC
), parameterized types (TypeDefinition.Sort.PARAMETERIZED
) or generic array types (TypeDefinition.Sort.GENERIC_ARRAY
) types. Generic array types never define methods and the returned list is always empty for such types.
-
getDeclaredMethods
public MethodList<MethodDescription.InGenericShape> getDeclaredMethods()
Returns the methods that this type declares.- Returns:
- The methods that this type declares.
-
getRecordComponents
public RecordComponentList<RecordComponentDescription.InGenericShape> getRecordComponents()
Returns the list of record components that are declared by this type. If this type is not a record, the returned list is empty.- Returns:
- A list of record components that this type declares.
-
getUpperBounds
public TypeList.Generic getUpperBounds()
Returns the upper bounds of this type. Any type with a well-defined upper bound is bound by at least one type. If no such type is defined, the bound is implicitly
Object
.Only non-symbolic type variables (
TypeDefinition.Sort.VARIABLE
, and wildcard types (TypeDefinition.Sort.WILDCARD
) have well-defined upper bounds. For other types, anIllegalStateException
is thrown.- Returns:
- The upper bounds of this type.
-
getLowerBounds
public TypeList.Generic getLowerBounds()
Returns the lower bounds of this type.
Only wildcard types (
TypeDefinition.Sort.WILDCARD
) define a lower bound. For other types, anIllegalStateException
is thrown.- Returns:
- The lower bounds of this type.
-
getComponentType
public TypeDescription.Generic getComponentType()
Returns the component type of this type.
Only non-generic types (
TypeDefinition.Sort.NON_GENERIC
) and generic array typesTypeDefinition.Sort.GENERIC_ARRAY
) define a component type. For other types, anIllegalStateException
is thrown.- Returns:
- The component type of this type or
null
if this type does not represent an array type.
-
getTypeArguments
public TypeList.Generic getTypeArguments()
Returns the type arguments of this type.
Parameters are only well-defined for parameterized types (
TypeDefinition.Sort.PARAMETERIZED
). For all other types, this method throws anIllegalStateException
.- Returns:
- A list of this type's type parameters.
-
findBindingOf
public TypeDescription.Generic findBindingOf(TypeDescription.Generic typeVariable)
Returns the parameter binding of the supplied type variable.
This method must only be called for parameterized types (
TypeDefinition.Sort.PARAMETERIZED
). For all other types, this method throws anIllegalStateException
.- Parameters:
typeVariable
- The type variable for which a value should be located.- Returns:
- The value that is bound to the supplied type variable or
null
if the type variable is not bound by this parameterized type.
-
getTypeVariableSource
public TypeVariableSource getTypeVariableSource()
Returns the source of this type variable. A type variable source is only well-defined for an attached type variable (TypeDefinition.Sort.VARIABLE
. For other types, this method throws anIllegalStateException
.- Returns:
- This type's type variable source.
-
getOwnerType
public TypeDescription.Generic getOwnerType()
Returns the owner type of this type. A type's owner type describes a nested type's declaring type. If it exists, the returned type can be a non-generic or parameterized type. If a class has no declaring type,
null
is returned.An owner type is only well-defined for parameterized types (
TypeDefinition.Sort.PARAMETERIZED
), for non-generic types (TypeDefinition.Sort.NON_GENERIC
) and for generic arrays (TypeDefinition.Sort.GENERIC_ARRAY
). For all other types, this method throws anIllegalStateException
.- Returns:
- This type's owner type or
null
if no owner type exists.
-
getTypeName
public java.lang.String getTypeName()
Returns the name of the type. For generic types, this name is theirObject.toString()
representations. For a non-generic type, it is the fully qualified binary name of the type.- Returns:
- The name of this type.
-
getSymbol
public java.lang.String getSymbol()
Returns the symbol of this type variable. A symbol is only well-defined for type variables (TypeDefinition.Sort.VARIABLE
,TypeDefinition.Sort.VARIABLE_SYMBOLIC
). For other types, this method throws anIllegalStateException
.- Returns:
- This type's type variable symbol.
-
getActualName
public java.lang.String getActualName()

visitor
- The visitor to apply.- Returns:
- The visitor's return value.
-
getStackSize
public StackSize getStackSize()

true
if this type description represents an array.
