      • hasValue

        public boolean hasValue​(Register register)
        Description copied from interface: ProcessorContextView
        Returns true if a value is defined for the given register.
        Specified by:
        hasValue in interface ProcessorContextView
        Parameters:
        register - the register to check for a value.
        Returns:
        true if the given register has a value.
      • 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
      • setDefaultValue

                                    Address start,
                                    Address end)
        Description copied from interface: DefaultProgramContext
        Associates a default value with the given register over the given range.
        Specified by:
        setDefaultValue in interface DefaultProgramContext
        Parameters:

        start - the start address.
        end - the end address (inclusive)
      • getDefaultValue

        public RegisterValue getDefaultValue​(Register register,
                                             Address address)
        Description copied from interface: DefaultProgramContext
        Returns the default value of a register at a given address.
        Specified by:
        getDefaultValue in interface DefaultProgramContext
        Parameters:
        register - the register for which to get a default value.
        address - the address at which to get a default value.
        Returns:
        the default value of the register at the given address or null if no default value has been assigned.
