ExpressionTypeNull

protected ExpressionTypeNull()

Create the no type instance that represents an unspecfied type for null literals.

Methodendetails

isPrimitiveOrBoxedPrimitive

public boolean isPrimitiveOrBoxedPrimitive()

Beschreibung aus Klasse kopiert: ExpressionType

Returns whether the type is a primitive type or a boxed primitive type.

Angegeben von:

isPrimitiveOrBoxedPrimitive in Klasse ExpressionType

Gibt zurück:

true if it is a primitive type and false otherwise

isAssignable

public int isAssignable(Transpiler transpiler,
 ExpressionType other)

Beschreibung aus Klasse kopiert: ExpressionType

Checks whether a values of the specified type other is assignable to a variable of this type or not. If a value of that type is not assignable a negative value is returned. A zero or positive value is returned if it is assignable. A zero value indicates a perfect type match and greater values indicate a less perfect type match, e.g. unboxing of a primitive type is required or the a value of a sub class type should be assigned.

Angegeben von:

isAssignable in Klasse ExpressionType

Parameter:

transpiler - the transpiler object used for utility methods

other - the other type

Gibt zurück:

a postive value or zero if the type is assignable and a negative value if not.

hashCode

public int hashCode()

Beschreibung aus Klasse kopiert: ExpressionType

Returns the hashCode for the expression type.

Setzt außer Kraft:

the hash code

equals

public boolean equals(Object obj)

Beschreibung aus Klasse kopiert: ExpressionType

Returns whether the object parameter ist equal to this expression type or not

Setzt außer Kraft:

equals in Klasse ExpressionType

Gibt zurück:

true if both are equal
