Method Detail

getInstance

public static StringProperty getInstance(java.lang.String value)

checkRange

public void checkRange(Range range)
                throws ValidationException

Description copied from class: Element

Determine if the element satisfies the given range constraint. This is used in the validation of the element. By default, this method with throw a ValidationException indicating that range checking of this element is not appropriate.

Overrides:

checkRange in class Element

Parameters:

range - Range to check Element against

Throws:

ValidationException - if the element cannot be compared to a range or if the element doesn't meet the range requirement

getValue

public java.lang.String getValue()

Description copied from class: Property

Return the value of this property as an Object. Subclasses may override this method to provide a more specific return type. Subclasses will have to call this method to obtain the value because the value itself is private.

Overrides:

getValue in class Property

Returns:

value of this property as an Object

getTypeAsString

public java.lang.String getTypeAsString()

Description copied from class: Element

All Elements must return a string describing its type. This value used in the serialization to machine profiles.

Specified by:

getTypeAsString in class Element

Returns:

String representation of Element's type

isKey

public boolean isKey()

Description copied from interface: Term

A utility function to determine if this Term is a key (String value).

Specified by:

isKey in interface Term

Returns:

boolean indicating if this Term is a key

getIndex

public java.lang.Integer getIndex()
                           throws InvalidTermException

Description copied from interface: Term

Method to extract the Integer index for this Term. This will throw an exception if the Term is not an index.

Specified by:

getIndex in interface Term

Returns:

Integer index of the Term

Throws:

InvalidTermException - thrown if the term is not an index; message should contain the string value of the term that was used

getKey

public java.lang.String getKey()
                        throws InvalidTermException

Description copied from interface: Term

Method to extract the String key for this Term. This will throw an exception if the Term is not a key.

Specified by:

getKey in interface Term

Returns:

String key of the Term

Throws:

InvalidTermException - thrown if the term is not a key; message should contain the string value of the term that was used
