AbstractValueTypeImpl

public AbstractValueTypeImpl(String name)

Method Detail

getName

public String getName()

Description copied from interface: ValueType

Returns the name of the variable type

Specified by:

getName in interface ValueType

toString

public String toString()

Overrides:

toString in class Object

isAbstract

public boolean isAbstract()

Description copied from interface: ValueType

Returns whether the value type is abstract. This is not related to the term abstract in the Java language.

Abstract value types cannot be used as types for variables but only used for querying.

Specified by:

isAbstract in interface ValueType

getParent

public ValueType getParent()

Description copied from interface: ValueType

Gets the parent value type.

Value type hierarchy is only relevant for queries and has the following meaning: When a value query is made (e.g. all tasks with a certain variable value), a "child" type's value also matches a parameter value of the parent type. This is only supported when the parent value type's implementation of ValueType.isAbstract() returns true.

Specified by:

getParent in interface ValueType

canConvertFromTypedValue

public boolean canConvertFromTypedValue(TypedValue typedValue)

Description copied from interface: ValueType

Determines whether the argument typed value can be converted to a typed value of this value type.

Specified by:

canConvertFromTypedValue in interface ValueType

convertFromTypedValue

public TypedValue convertFromTypedValue(TypedValue typedValue)

Description copied from interface: ValueType

Converts a typed value to a typed value of this type. This does not suceed if ValueType.canConvertFromTypedValue(TypedValue) returns false.

Specified by:

convertFromTypedValue in interface ValueType

unsupportedConversion

protected IllegalArgumentException unsupportedConversion(ValueType typeToConvertTo)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

isTransient

protected Boolean isTransient(Map<String,Object> valueInfo)
