public class UnknownType
extends Type

UnknownType describe the case in which it is not possible for the CPG to determine which Type is used. E.g.: This occurs when the type is inferred by the compiler automatically when using keywords such as auto in cpp

Method Details

getUnknownType

public static @NonNull UnknownType getUnknownType()

Use this function to obtain an UnknownType or call the TypeParser with the typeString UNKNOWN

Returns:

UnknownType instance

reference

public Type reference(PointerType.PointerOrigin pointerOrigin)

Specified by:

reference in class Type

Parameters:

pointerOrigin - Reason for the reference (array of pointer)

Returns:

Same UnknownType, as it is makes no sense to obtain a pointer/reference to an UnknownType

dereference

public Type dereference()

Specified by:

dereference in class Type

Returns:

Same UnknownType,

duplicate

public Type duplicate()

Specified by:

duplicate in class Type

Returns:

Creates an exact copy of the current type (chain)

hashCode

public int hashCode()

Overrides:

hashCode in class Type

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class Type

toString

public java.lang.String toString()

Overrides:

toString in class Type

setStorage

public void setStorage(@NonNull Type.Storage storage)

Overrides:

setStorage in class Type

setQualifier

public void setQualifier(Type.Qualifier qualifier)

Overrides:

setQualifier in class Type

setTypeOrigin

public void setTypeOrigin(Type.Origin origin)

Overrides:

setTypeOrigin in class Type
