XDataType

public XDataType(java.lang.Object name,
                 Type implementationType,
                 int typeCode)
Method Detail

getReflectClass

public java.lang.Class getReflectClass()
Description copied from class: Type
Get the java.lang.Class object for the representation type.

Overrides:
getReflectClass in class Type

getImplementationType

public Type getImplementationType()
Description copied from class: Type
The type used to implement types not natively understood by the JVM. Usually, the identity function. However, a language might handle union types or template types or type expressions calculated at run time. In that case return the type used at the JVM level, and known at compile time.

Specified by:
getImplementationType in interface TypeValue
Overrides:
getImplementationType in class Type

emitCoerceFromObject

public void emitCoerceFromObject(CodeAttr code)
Description copied from class: Type
Compile code to coerce/convert from Object to this type.

Overrides:
emitCoerceFromObject in class Type

emitCoerceToObject

public void emitCoerceToObject(CodeAttr code)
Description copied from class: Type
Compile code to convert a object of this type on the stack to Object.

Overrides:
emitCoerceToObject in class Type

emitTestIf

public void emitTestIf(Variable incoming,
                       Declaration decl,
                       Compilation comp)
Description copied from interface: TypeValue
Emit code for if (incoming instanceof this_type) decl = incoming .... This method is designed for typeswitch applications, where this call is the first part of a conditional, so it must be followed by calls to emitElse and emitFi.

Specified by:
emitTestIf in interface TypeValue
Parameters:
incoming - Contains the value we are testing to see if it has the type of this. If null, use top-of-stack. May not be null if incoming is non-null.
decl - If non-null, assign value after coercion to Declaration.
comp - The compilation state.

isInstance

public boolean isInstance(java.lang.Object obj)
Overrides:
isInstance in class Type

emitIsInstance

public void emitIsInstance(Variable incoming,
                           Compilation comp,
                           Target target)
Description copied from interface: TypeValue
Emit code for incoming instanceof this_type. The implementation can use InstanceOf .emitIsInstance which is a conveniece method that calls emitTestIf.

Specified by:
emitIsInstance in interface TypeValue
Parameters:
incoming - Contains the value we are testing to see if it has the the type of 'this'. If null, use top-of-stack.
comp - The compilation state.
target - Where to leave the result.

toString

public java.lang.String toString(java.lang.Object value)

print

public void print(java.lang.Object value,
                  Consumer out)

castable

public boolean castable(java.lang.Object value)

cast

public java.lang.Object cast(java.lang.Object value)

coerceFromObject

public java.lang.Object coerceFromObject(java.lang.Object obj)
Description copied from class: Type
Convert an object to a value of this Type. Throw a ClassCastException when this is not possible.

Specified by:
coerceFromObject in class Type

compare

public int compare(Type other)
Description copied from class: Type
Return a numeric code showing "subtype" relationship: 1: if other is a pure subtype of this; 0: if has the same values; -1: if this is a pure subtype of other; -2: if they have values in common but neither is a subtype of the other; -3: if the types have no values in common. "Same member" is rather loose; by "A is a subtype of B" we mean that all instance of A can be "widened" to B. More formally, A.compare(B) returns: 1: all B values can be converted to A without a coercion failure (i.e. a ClassCastException or overflow or major loss of information), but not vice versa. 0: all A values can be converted to B without a coercion failure and vice versa; -1: all A values can be converted to B without a coercion failure not not vice versa; -2: there are (potentially) some A values that can be converted to B, and some B values can be converted to A; -3: there are no A values that can be converted to B, and neither are there any B values that can be converted to A.

Specified by:
compare in class Type

valueOf

public java.lang.Object valueOf(java.lang.String value)

makeFloat

public static java.lang.Float makeFloat(float value)

makeDouble

public static java.lang.Double makeDouble(double value)

getConstructor

public Procedure getConstructor()
Description copied from interface: TypeValue
Get the constructor function for this type. Returns null if there is no contructor function. Also returns null if this extends ClassType or ArrayType and standard Java constructors ( methods) should be used.

Specified by:
getConstructor in interface TypeValue
