      • hasValue

        public boolean hasValue​(Register register)
        Description copied from interface: ProcessorContextView

      • setValue

        public void setValue​(Register register,
                             java.math.BigInteger value)

        Sets the value for a Register.
        Specified by:
        setValue in interface ProcessorContext
        Parameters:
        register - the register to have its value set
        value - the value for the register (null is not permitted).
      • setFutureRegisterValue

        public void setFutureRegisterValue​(Address address,
                                           RegisterValue value)
        Description copied from interface: DisassemblerContext
        Combines value with any previously saved future register value at address or any value stored in the program if there is no previously saved future value. Use this method when multiple flows to the same address don't matter or the flowing from address is unknown.
        When value has conflicting bits with the previously saved value, value will take precedence.
        If the register value is the value for the processor context register and a previously saved value does not exist, the user saved values in the stored context of the program will be used as existing value.
        Specified by:
        setFutureRegisterValue in interface DisassemblerContext
        Parameters:
        address - the address to store the register value
        value - the register value to store at the address
      • setFutureRegisterValue

        public void setFutureRegisterValue​(Address fromAddr,
                                           Address toAddr,
                                           RegisterValue value)
        Description copied from interface: DisassemblerContext
        Combines value with any previously saved future register value at fromAddr/toAddr or any value stored in the program if there is no previously saved future value.
        When value has conflicting bits with the previously saved value, value will take precedence.
        If the register value is the value for the processor context register and a previously saved value does not exist, the user saved values in the stored context of the program will be used as existing value.
        Specified by:
        setFutureRegisterValue in interface DisassemblerContext
        Parameters:
        fromAddr - the address this value if flowing from
        toAddr - the address to store the register value
        value - the register value to store at the address
