## Interface ICurrencyField

- All Superinterfaces:
    IField

      public interface ICurrencyField
      extends IField

  Represents a currency field. Only the local currency, local amount and exchange rate values can be set. Base amount and base currency (code) are read-only.

  Null currency values

  If you wish to set the value of this currency field to be "null" you can set the local currency and local amount values to null using the relevant setters, this results in the currency being treated as null by the system.

  Note you must always call `setLocalAmount(Double)` before calling `setLocalCurrency(ICurrency)` if setting the values to null.

- - ### Method Detail

    - #### getBaseAmount

          java.lang.Double getBaseAmount()

      Returns the currency base amount. The base amount is a computed value (local amount * exchange rate). Changing the local amount doesn't automatically recompute this value. The object needs to be saved for this value to be recomputed.
      Returns:
        the currency base amount

    - #### getExchangeRate

          java.lang.Double getExchangeRate()

      Returns the exchange rate.
      Returns:
        the exchange rate

    - #### getBaseCurrency

          ICurrency getBaseCurrency()

      Returns the base currency.
      Returns:
        the base currency

    - #### getLocalAmount

          java.lang.Double getLocalAmount()

      Returns the local amount.
      Returns:
        the local amount

    - #### getLocalCurrency

          ICurrency getLocalCurrency()

      Returns the local currency.
      Returns:
        the local currency

    - #### setLocalAmount

          void setLocalAmount(java.lang.Double localAmount)

      Sets the local amount. Can be set to null. See also `setLocalCurrency(ICurrency)` if desire to set both local amount and local currency to null the local amount needs to be set to null first.
      Parameters:
        `localAmount` - the local amount

    - #### setLocalCurrency

          void setLocalCurrency(ICurrency currency)

      Sets the local currency. Local currency may not be set to null when there is a non-null local amount.
      Parameters:
        `currency` - the local currency

    - #### setExchangeRate

          void setExchangeRate(java.lang.Double exchangeRate)

      Sets the exchange rate.
      Parameters:
        `exchangeRate` - exchange rate
