Method Detail

• getTypeRegistry

  public SoyTypeRegistry getTypeRegistry()

• computeLowestCommonType

  public SoyType computeLowestCommonType(SoyType t0,
                                SoyType t1)

  Compute the most specific type that is assignable from both t0 and t1.

  Parameters:

  t0 - A type.

  t1 - Another type.

  Returns:

  A type that is assignable from both t0 and t1.

• computeLowestCommonType

  public SoyType computeLowestCommonType(Collection<SoyType> types)

  Compute the most specific type that is assignable from all types within a collection.

  Parameters:

  types - list of types.

  Returns:

  A type that is assignable from all of the listed types.

• computeLowestCommonTypeArithmetic

  public com.google.common.base.Optional<SoyType> computeLowestCommonTypeArithmetic(SoyType t0,
                                                                           SoyType t1)

  Compute the most specific type that is assignable from both t0 and t1, taking into account arithmetic promotions - that is, converting int to float if needed.

  Parameters:

  t0 - A type.

  t1 - Another type.

  Returns:

  A type that is assignable from both t0 and t1 or absent if the types are not arithmetic meaning a subtype of 'number' or unknown.

• isNumericOrUnknown
