Record Class ConcreteTypeKey

java.lang.Object
java.lang.Record
com.ibm.wala.ipa.callgraph.propagation.ConcreteTypeKey
All Implemented Interfaces:
ContextItem, InstanceKey
public record ConcreteTypeKey(IClass type) extends Record implements InstanceKey
An instance key which represents a unique set for each concrete type.

  • Constructor Details

    • ConcreteTypeKey

      public ConcreteTypeKey(IClass type)
      Creates an instance of a ConcreteTypeKey record class.
      Parameters:
      type - the value for the type record component

  • Method Details

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • getType

      @Deprecated(forRemoval=true, since="1.8.0") public IClass getType()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Use type() instead

    • concreteType

      public IClass concreteType()
      Description copied from interface: InstanceKey
      For now, we assert that each InstanceKey represents a set of classes which are all of the same concrete type (modulo the fact that all arrays of references are considered concrete type []Object;)
      Specified by:
      concreteType in interface InstanceKey

    • getInstanceKeysForPEI

      public static InstanceKey[] getInstanceKeysForPEI(SSAInstruction pei, IClassHierarchy cha)
      Parameters:
      pei - a PEI instruction
      cha - governing class hierarchy
      Returns:
      an array of ConcreteTypeKeys that represent the exceptions the PEI may throw.
      Throws:
      IllegalArgumentException - if pei is null

    • getCreationSites

      public Iterator<Pair<CGNode, NewSiteReference>> getCreationSites(CallGraph CG)
      Description copied from interface: InstanceKey
      Get the creation sites of this, i.e., the statements that may allocate objects represented by this. A creation site is a pair (n,s), where n is the containing CGNode in the given CallGraph CG and s is the allocating NewSiteReference.
      Specified by:
      getCreationSites in interface InstanceKey

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • type

      public IClass type()
      Returns the value of the type record component.
      Returns:
      the value of the type record component
