Method Detail

defineVariable

public void defineVariable(VariableMapping mapping)

Define the specified variable mapping. This is to be used by the context to setup the variable definitions. Do not call it directly. You will have unexpected results if you have a variable defined in this class, but not in the context.

Parameters:

mapping - The variable mapping.

getVariable

public ExpressionValue getVariable(int i)

Get a variable value by index.

Parameters:

i - The index of the variable we are using.

Returns:

The variable at the specified index.

getVariable

public ExpressionValue getVariable(String name)

Get a variable value by name.

Parameters:

name - The name of the variable we are using.

Returns:

The variable at the specified index.

getVariableIndex

public int getVariableIndex(String varName)

Get a variable index by name.

Parameters:

varName - The variable name.

Returns:

The index of the specified variable.

getVariableName

public String getVariableName(int idx)

Get a variable name by index.

Parameters:

idx - The variable index.

Returns:

The variable name.

setVariable

public void setVariable(int index,
                        double value)

Set a variable floating point value by index.

Parameters:

index - The index.

value - The value.

setVariable

public void setVariable(String name,
                        double d)

Set a floating point variable value by name.

Parameters:

name - The name.

d - The value.

setVariable

public void setVariable(String name,
                        ExpressionValue value)

Set a variable value by name.

Parameters:

name - The variable name.

value - The value.

size

public int size()

Returns:

Get the number of variables defined.

variableExists

public boolean variableExists(String name)

Determine if the specified variable name exists.

Parameters:

name - The name of the variable.

Returns:

True if the name already exists.
