      Description copied from interface: ProcessorContextView
      Get a Register given the name of a register
      Specified by:
      getRegister in interface ProcessorContextView
      Parameters:
      name - the name of the register.
      Returns:
      The register with the given name.

    • getValue

      default BigInteger getValue(Register register, boolean signed)
      Description copied from interface: ProcessorContextView
      Get the contents of a processor register as a BigInteger object
      Specified by:
      getValue in interface ProcessorContextView
      Parameters:
      register - register to get the value for
      Returns:
      a BigInteger object containing the value of the register if a value exists, otherwise null.

    • getRegisterValue

      default RegisterValue getRegisterValue(Register register)
      Description copied from interface: ProcessorContextView
      Get the RegisterValue for the given register.
      Specified by:
      getRegisterValue in interface ProcessorContextView
      Parameters:
      register - register to get the value for
      Returns:
      RegisterValue object containing the value of the register if a value exists, otherwise null.

    • hasValue

      default 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.

    • setValue

      default void setValue(Register register, BigInteger value) throws ContextChangeException
      Description copied from interface: ProcessorContext
      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).
      Throws:
      ContextChangeException - an illegal attempt to change context was made

    • setRegisterValue

      default void setRegisterValue(RegisterValue value) throws ContextChangeException
      Description copied from interface: ProcessorContext
      Sets the specified register value within this context.
      Specified by:
      setRegisterValue in interface ProcessorContext
      Parameters:
      value - register value
      Throws:
      ContextChangeException - an illegal attempt to change context was made

    • clearRegister

      default void clearRegister(Register register) throws ContextChangeException
      Description copied from interface: ProcessorContext
      Clears the register within this context.
      Specified by:
      clearRegister in interface ProcessorContext
      Parameters:
      register - register to be cleared.
      Throws:
      ContextChangeException - an illegal attempt to change context was made

    • setFutureRegisterValue

      default 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

      default 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
