    • Method Detail

      • getName

        java.lang.String getName()
        Get the actual name of this equate. Note that this name may be different than the "display name," which is what the user will see.
        Returns:
        The actual name of this equate.

      • getDisplayName

        java.lang.String getDisplayName()
        Gets the "display name" of this equate. Note that the display name may be different than the equate's actual name if the equate is based off a data type id.
        Returns:
        The "display name" of this equate.

      • getValue

        long getValue()
        Get the value of this equate.

      • getDisplayValue

        java.lang.String getDisplayValue()
        Gets a more accurate representation of the equate value. Used for rendering as close to the listing as possible.
        Returns:
        A more accurate representation of the equate value.

      • getReferenceCount

        int getReferenceCount()
        Get the number of references to this equate.

      • addReference

        void addReference​(Address refAddr,
                  int opndPosition)
        Add a reference (at the given operand position) to this equate. If a reference already exists for the instruction at this address, then the old reference will be removed before the new reference is added.
        Parameters:
        refAddr - the address where the equate is used.
        opndPosition - the operand index where the equate is used.

      • addReference

        void addReference​(long dynamicHash,
                  Address refAddr)
        Add a reference (at the given dynamic hash position) to this equate. If a reference already exists for the instruction at this address, then the old reference will be removed before the new reference is added.
        Parameters:
        dynamicHash - constant varnode dynamic hash value
        refAddr - the address where the equate is used.

      • getReferences

        EquateReference[] getReferences()
        Get the references for this equate.
        Returns:
        a array of EquateReferences.

      • getReferences

        java.util.List<EquateReference> getReferences​(Address refAddr)
        Get references for this equate attached to a specific address
        Parameters:
        refAddr - is the address
        Returns:
        the list of EquateReferences

      • removeReference

        void removeReference​(Address refAddr,
                     int opndPosition)
        Remove the reference at the given operand position.
        Parameters:
        refAddr - the address that was using this equate
        opndPosition - the operand index of the operand that was using this eqate.

      • removeReference

        void removeReference​(long dynamicHash,
                     Address refAddr)
        Remove the reference at the given address
        Parameters:
        dynamicHash - the hash of the reference
        refAddr - the reference's address

      • isValidUUID

        boolean isValidUUID()
        Checks if equate is based off an enum's universal id and checks if the enum still exists. The equate is still valid if the equate is not based off an enum.
        Returns:
        true if the equate is based off an enum that still exists.

      • isEnumBased

        boolean isEnumBased()

        Returns:
        The universal id for this equate.

      • toString

        java.lang.String toString()
        Get the name of this equate.
        Overrides:
        toString in class java.lang.Object
