Package org.microproxy.starlark

Class ProtoFixed

java.lang.Object
org.microproxy.starlark.ProtoFixed
All Implemented Interfaces:
org.microproxy.thirdparty.starlark.eval.StarlarkValue, org.microproxy.thirdparty.starlark.eval.Structure
public final class ProtoFixed extends Object implements org.microproxy.thirdparty.starlark.eval.Structure
A fixed-width protobuf value in a script: what protobuf.decode gives for a field with wire type fixed32 or fixed64 (without a schema it could be an integer or a float), and what protobuf.fixed32(x) and protobuf.fixed64(x) make. It encodes back with its wire type. Fields: bits (32 or 64), value (unsigned), signed and float. Two are equal when their bits and widths are.

  • Method Details

    • getAssociatedTypeConstructor

      public static org.microproxy.thirdparty.starlark.syntax.TypeConstructor getAssociatedTypeConstructor()
      Types the builtins that return this class (see ScriptType).
      Returns:
      the Starlark type constructor for fixed-width values

    • getStarlarkType

      public org.microproxy.thirdparty.starlark.syntax.StarlarkType getStarlarkType(org.microproxy.thirdparty.starlark.eval.StarlarkSemantics semantics)
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.Structure
      Returns the Starlark type of this struct. For efficiency, implementations should override this method to return a memoized value.
      Specified by:
      getStarlarkType in interface org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Specified by:
      getStarlarkType in interface org.microproxy.thirdparty.starlark.eval.Structure
      Parameters:
      semantics - the interpreter settings used to determine the type
      Returns:
      the type of this value, or null when no type information is provided

    • getValue

      public Object getValue(String name)
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.Structure
      Returns the value of the field with the given name, or null if the field does not exist. The interpreter (Starlark code) calls the getValue below, which has access to StarlarkSemantics.

      The set of names for which getValue returns non-null should match getFieldNames if possible.

      Specified by:
      getValue in interface org.microproxy.thirdparty.starlark.eval.Structure
      Parameters:
      name - the name of the field to retrieve
      Returns:
      the field value, or null if the field does not exist

    • getFieldNames

      public com.google.common.collect.ImmutableList<String> getFieldNames()
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.Structure
      Returns the names of this value's fields, in some undefined but stable order.

      A call to getValue for each of these names should return non-null, though this is not enforced.

      The Starlark expression dir(x) reports the union of getFieldNames() and any StarlarkMethod-annotated fields and methods of this value.

      Specified by:
      getFieldNames in interface org.microproxy.thirdparty.starlark.eval.Structure
      Returns:
      the field names in a stable order

    • getErrorMessageForUnknownField

      public String getErrorMessageForUnknownField(String field)
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.Structure
      Returns the error message to print for an attempt to access an undefined field.

      May return null to use a default error message.

      Specified by:
      getErrorMessageForUnknownField in interface org.microproxy.thirdparty.starlark.eval.Structure
      Parameters:
      field - the undefined field name
      Returns:
      the diagnostic message, or null to use the default

    • isImmutable

      public boolean isImmutable()
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Reports whether the value is deeply immutable.
      Specified by:
      isImmutable in interface org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Returns:
      whether this value and all values reachable from it are immutable

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • repr

      public void repr(org.microproxy.thirdparty.starlark.eval.Printer printer, org.microproxy.thirdparty.starlark.eval.StarlarkSemantics semantics)
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Prints an official representation of object x.

      Convention is that the string should be parseable back to the value x. If this isn't feasible then it should be a short human-readable description enclosed in angled brackets, e.g. "<foo object>".

      Specified by:
      repr in interface org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Parameters:
      printer - a printer to be used for formatting nested values.
      semantics - the interpreter settings used to format nested values
