Class UnknownType

java.lang.Object

com.google.template.soy.types.primitive.PrimitiveType

com.google.template.soy.types.primitive.UnknownType

All Implemented Interfaces:

SoyType

public class UnknownType
extends PrimitiveType

The "unknown" type is used to indicate that the type was unspecified or could not be inferred. Variables with unknown type are considered to be dynamically-typed, and all operations are allowed (but may fail at runtime).

Method Detail

getKind

public SoyType.Kind getKind()

Description copied from interface: SoyType

Returns what kind of type this is.

isAssignableFrom

public boolean isAssignableFrom(SoyType srcType)

Description copied from interface: SoyType

Returns true if a parameter or field of this type can be assigned from a value of srcType.

Specified by:

isAssignableFrom in interface SoyType

Overrides:

isAssignableFrom in class PrimitiveType

Parameters:

srcType - The type of the incoming value.

Returns:

True if the assignment is valid.

isInstance

public boolean isInstance(SoyValue value)

Description copied from interface: SoyType

Returns true if the given value is an instance of this type. For generic types, this only checks the overall shape of the type (list, map, etc) since Java type erasure does not allow the type parameters to be checked. Also, in some cases the "instanceof" test may be defined somewhat loosely - for example, sanitized types may be considered instances of type string, since they are usable in any context where a string is usable, even though internally they are not implemented as subclasses of string. This test does not take into account automatic coercions, such as converting to string or boolean.

Parameters:

value - The value to test.

Returns:

True if the value is an instance of this type.

javaType

public Class<? extends SoyValue> javaType()

Description copied from interface: SoyType

Returns the java class for the the SoyValue subclass that is used to represent this type.

toString

public String toString()

Overrides:

toString in class Object

getInstance

public static UnknownType getInstance()

Return the single instance of this type.
