Whether parameter is modifiable

getScope

public Parameter.Scope getScope()

Description copied from interface: Parameter

Returns the scope where this parameter is defined.

Specified by:

getScope in interface Parameter

Returns:

Scope of the parameter

getType

public Type getType()

Description copied from interface: Parameter

Returns the type of this Parameter.

Specified by:

getType in interface Parameter

Returns:

Type of the parameter

getDefaultExp

public Exp getDefaultExp()

Description copied from interface: Parameter

Returns the expression which provides the default value for this Parameter. Never null.

Specified by:

getDefaultExp in interface Parameter

Returns:

Default value expression of the parameter

getName

public String getName()

Description copied from interface: Parameter

Returns the name of this Parameter.

Specified by:

getName in interface Parameter

Returns:

Name of the parameter

getDescription

public String getDescription()

Returns the description of this Parameter.

Specified by:

getDescription in interface Parameter

Returns:

Description of the parameter

getValue

public Object getValue()

Description copied from interface: Parameter

Returns the value of this parameter.

If Parameter.setValue(Object) has not been called, returns the default value of this parameter.

The type of the value is (depending on the type of the parameter) a String, Number, or Member.

Specified by:

getValue in interface Parameter

Returns:

The value of this parameter

setValue

public void setValue(Object value)

Description copied from interface: Parameter

Sets the value of this parameter.

Specified by:

setValue in interface Parameter

Parameters:

value - Value of the parameter; must be a String, a Double, or a Member

isSet

public boolean isSet()

Description copied from interface: Parameter

Returns whether the value of this parameter has been set.

If the value has not been set, this parameter will return its default value.

Setting a parameter to null is not equivalent to unsetting it. To unset a parameter, call Parameter.unsetValue().

Specified by:

isSet in interface Parameter

Returns:

Whether this parameter has been assigned a value

unsetValue

public void unsetValue()

Description copied from interface: Parameter

Unsets the value of this parameter.

After calling this method, the parameter will revert to its default value, as if Parameter.setValue(Object) had not been called, and Parameter.isSet() will return false.

Specified by:

unsetValue in interface Parameter

compile

public Calc compile(ExpCompiler compiler)

Specified by:

compile in interface ParameterCompilable
