Interface PasswordContainer

All Known Implementing Classes:
OneWireContainer37, OneWireContainer41
public interface PasswordContainer
Public interface for all devices which implement some form of password protection. The operation protected could be reading from the device, writing to the device, or both. These interface methods will allow you to set the passwords on the device, enable/disable the passwords on the device, and set the passwords for the API to use when interacting with the device.

      true if the device has the capability to enable one type of password while leaving another type disabled.

    • setDevicePasswordEnable

      void setDevicePasswordEnable(boolean enableReadOnly, boolean enableReadWrite, boolean enableWriteOnly) throws OneWireException, OneWireIOException

      Enables/Disables passwords for this Device. This method allows you to individually enable the different types of passwords for a particular device. If hasSinglePasswordEnable() returns true, you can selectively enable particular types of passwords. Otherwise, this method will throw an exception if all supported types are not enabled.

      For this to be successful, either write-protect passwords must be disabled, or the write-protect password(s) for this container must be set and must match the value of the write-protect password(s) in the device's register.

      Parameters:
      enableReadOnly - if true Read-Only passwords will be enabled.
      enableReadWrite - if true Read/Write passwords will be enabled.
      enableWriteOnly - if true Write-Only passwords will be enabled.
      Throws:
      OneWireException
      OneWireIOException

    • setDevicePasswordEnableAll

      void setDevicePasswordEnableAll(boolean enableAll) throws OneWireException, OneWireIOException

      Enables/Disables passwords for this device. If the part has more than one type of password (Read-Only, Write-Only, or Read/Write), all passwords will be enabled. This function is equivalent to the following: owc41.setDevicePasswordEnable( owc41.hasReadOnlyPassword(), owc41.hasReadWritePassword(), owc41.hasWriteOnlyPassword() );

      For this to be successful, either write-protect passwords must be disabled, or the write-protect password(s) for this container must be set and must match the value of the write-protect password(s) in the device's register.

      Parameters:
      enableAll - if true, all passwords are enabled. Otherwise, all passwords are disabled.
      Throws:
      OneWireException
      OneWireIOException

      For this to be successful, either write-protect passwords must be disabled, or the write-protect password(s) for this container must be set and must match the value of the write-protect password(s) in the device's register.

      Parameters:
      password - the new password to be written to the device's Read-Only password register. Length must be (offset + getReadOnlyPasswordLength)
