Method Details

getValue

public Object getValue(String value)

Description copied from class: ValueClassNameDatatype

This method parses the given string and returns the value as an instance of the class this value datatype represents. Use with caution: During development time Faktor-IPS maintains all values with their string representation. This allows to change the value's datatype without the need to convert the value from one class to another (e.g. if the string representation is 42 you can change the datatype from integer to string without converting the integer object to a string object.

Specified by:

getValue in interface ValueDatatype

Specified by:

getValue in class ValueClassNameDatatype

Parameters:

value - string representation of the value

Returns:

The value as instance of the class this datatype represents.

See Also:

• ValueClassNameDatatype.valueToString(Object)

isParsable

public boolean isParsable(String value)

Description copied from interface: ValueDatatype

Returns true if the given string can be parsed to a value of this datatype. Returns false otherwise.

Specified by:

isParsable in interface ValueDatatype

Overrides:

isParsable in class ValueClassNameDatatype

valueToString

public String valueToString(Object value)

Description copied from class: ValueClassNameDatatype

Returns the string representation of the given value. The String value returned by this method must be parsable by the ValueClassNameDatatype.getValue(String) method.

Specified by:

valueToString in interface ValueDatatype

Overrides:

valueToString in class ValueClassNameDatatype

Parameters:

value - a value of this datatype

Returns:

the value's string representation

See Also:

• ValueClassNameDatatype.getValue(String)

getDateValue

public Date getDateValue(String value)

Calls the getValue(String) method and casts the result to a Date.

supportsCompare

public boolean supportsCompare()

Returns:

true if this datatype is able to compare two values.
