All Implemented Interfaces:

HasType.SecondaryTypeEdge, Persistable, IVisitable<de.fraunhofer.aisec.cpg.graph.Node>

public class ObjectType
extends Type
implements HasType.SecondaryTypeEdge

This is the main type in the Type system. ObjectTypes describe objects, as instances of a class. This also includes primitive data types.

boolean primitive)

ObjectType

public ObjectType()

Method Details

updateType

public void updateType(java.util.Collection<Type> typeState)

Specified by:

updateType in interface HasType.SecondaryTypeEdge

replaceGenerics

public void replaceGenerics(Type oldType,
Type newType)

getGenerics

public java.util.List<Type> getGenerics()

getGenericPropertyEdges

public java.util.List<de.fraunhofer.aisec.cpg.graph.edge.PropertyEdge<Type>> getGenericPropertyEdges()

getRecordDeclaration

public RecordDeclaration getRecordDeclaration()

setRecordDeclaration

public void setRecordDeclaration(RecordDeclaration recordDeclaration)

reference

public PointerType reference(PointerType.PointerOrigin pointerOrigin)

Specified by:

reference in class Type

Parameters:

pointerOrigin - Reason for the reference (array of pointer)

Returns:

PointerType to a ObjectType, e.g. int*

dereference

public Type dereference()

Specified by:

dereference in class Type

Returns:

UnknownType, as we cannot infer any type information when dereferencing an ObjectType, as it is just some memory and its interpretation is unknown

duplicate

public Type duplicate()

Specified by:

duplicate in class Type

Returns:

Creates an exact copy of the current type (chain)

setGenerics

public void setGenerics(java.util.List<Type> generics)

addGeneric

public void addGeneric(Type generic)

addGenerics

public void addGenerics(java.util.List<Type> generics)

isSimilar

public boolean isSimilar(Type t)

Description copied from class: Type

Required for possibleSubTypes to check if the new Type should be considered a subtype or not

Overrides:

isSimilar in class Type

Parameters:

t - other type the similarity is checked with

Returns:

True if the parameter t is equal to the current type (this)

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class Type

hashCode

public int hashCode()

Overrides:

hashCode in class Type
