All Implemented Interfaces:

java.lang.Cloneable, java.util.Map, java.io.Serializable

public class Variable

extends ModelComponent

global variable: similar to Java "static public" variable. A global variable can be constant or modifiable denoted by the final field. A global variable has a name, a value and an alias. The value could be a general expression such as pi/4 where pi is another constant variable.

Method Detail

getType

public java.lang.String getType()

Get alias of the type of the variable.

Returns:

alias of the type of the variable

setType

public void setType(java.lang.String typeAlias)

Set the type of the variable.

Parameters:

typeAlias - alias of the type to be set

getTypeOptions

public java.lang.String[] getTypeOptions()

Get type options.

Returns:

the list of fact type alias includeing primitive, RL and Java Fact types, but excluding void.

getTypeSelected

public int getTypeSelected()

Get the index of the selected value for the property type options.

Returns:

the index of the selected value for the type choice list

getValue

public InitValue getValue()

Get the Value of the variable

Returns:

value of the variable

getFinal

public boolean getFinal()

Whether the variable is final?

Returns:

true if it is final

setFinal

public void setFinal(boolean isFinal)

Set the variable final

Parameters:

isFinal - boolean value

validate

public void validate()
              throws RulesSDKDMValidationException

validate consistency of the global variable definition

Overrides:

validate in class ModelComponent

Throws:

thrown - if any of the following happens (1)no initial value is assigned (2)type is not defined in the datamodel (3) Alias is conflicted with other global variable

RulesSDKDMValidationException

get

public java.lang.Object get(java.lang.Object key)

Overwrite hashtable get method. For property "Type", "Type_Selected", Type_Options we don't return the hashtable entry directly. Instead, we compute them dynamically.

Specified by:

get in interface java.util.Map

Overrides:

get in class ModelComponent

Parameters:

key - a String containing the property name to be fetched.

Returns:

the value corresponding to the key

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

Overwrite hashtable put method. For property "type" we don't put the value (alias) directly. We get id of the type from alias, then put it into the table.

Parameters:

key - a String containing the property name to be saved.

value - a String corresponding to the key to be saved
