Method Detail

calc

public float calc(float input)

Description copied from class: org.vishia.util.CalculatorExpr

Calculates the expression with only one input. This is a simple variant for scaling values etc. It invokes internally CalculatorExpr.calcDataAccess(Map, Object...) but without a access Map. It means it must not contain access to other data.

Overrides:

calc in class CalculatorExpr

Parameters:

input - The only one input value.

Returns:

The result.

calcDataAccess

public CalculatorExpr.Value calcDataAccess(java.util.Map<java.lang.String,DataAccess.Variable<java.lang.Object>> javaVariables,
                                           java.lang.Object... args)
                                    throws java.lang.Exception

Description copied from class: org.vishia.util.CalculatorExpr

Calculates the expression with possible access to any stored object data with access via reflection.

Overrides:

calcDataAccess in class CalculatorExpr

Parameters:

javaVariables - Any data which are access-able with its name. It is the first part of a datapath.

args - Some args given immediately. Often numerical args. Often not used.

Returns:

The result wrapped with a Value instance. This Value contains also the type info.

Throws:

java.lang.Exception - Any exception is possible. Especially NoSuchFieldException or such if the access via reflection is done.
