Method Detail

isFinal

public boolean isFinal()

Whether it is a final field

Returns:

true to indicate the field is final

isStatic

public boolean isStatic()

Whether it is a static field

Returns:

true to indicate the field is static

getType

public java.lang.String getType()

Get alias of the type of the field

Returns:

the alias of the type

getDefaultValue

public InitValue getDefaultValue()

Get default of the field

Returns:

default value of the field

isTypePrimitive

public boolean isTypePrimitive()

Whether the type of the field is primitive (i.e. int, char, double etc.)?

Returns:

true if type is primitive; false if type is java or RL class

getAllowChaining

public boolean getAllowChaining()

Allow expression chaining, e.g. a.b.foo(). It only applies to the fields of complex type. In another word, if the type of the field is primitive, the method always return false.

Returns:

true to indicate the property can be chained to make up new expressions

setAllowChaining

public void setAllowChaining(boolean allowChaining)

Set to allow the field to be chained to make up new expressions

Parameters:

allowChaining - true indicates that the field can be chained to make up new expressions

validate

public void validate()
              throws RulesSDKDMValidationException

Description copied from class: ModelComponent

valid the model component

Overrides:

validate in class ModelComponent

Throws:

RulesSDKDMValidationException

get

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

Overwrite hashtable get method. For property "type" we don't return the hashtable entry directly. Instead, we compute the type alias from type id which is the hashtable entry.

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
