Method Detail

getElementType

public TypeInfo getElementType()

Description copied from interface: TypeInfo

If this type is a collection of element type, this method returns the TypeInfo of the element type. Otherwise, this method return false.

Specified by:

getElementType in interface TypeInfo

Overrides:

getElementType in class JavaTypeProvider.JavaTypeInfo

Returns:

the TypeInfo of element type. Otherwise, return null.

See Also:

TypeInfo.getElementType()

isAssignableFrom

public boolean isAssignableFrom(TypeInfo other)

Description copied from interface: TypeInfo

This method tests if this type is asssignable from other type. This method should also handle auto-boxing and auto-unboxing for primitive types.

Specified by:

isAssignableFrom in interface TypeInfo

Overrides:

isAssignableFrom in class JavaTypeProvider.JavaTypeInfo

Parameters:

other - - the type to assign to this type.

Returns:

true if the test condition passes.

See Also:

TypeInfo.isAssignableFrom(ariba.util.fieldtype.TypeInfo)

isCompatible

public boolean isCompatible(TypeInfo other)

Description copied from interface: TypeInfo

This method returns true if one type is assignable to another. This implies that one type is convertible to another through reference widening or narrowing. For primitive type, this method can also return true if the two types can be promoted into a common type. This method should also handle auto-boxing and auto-unboxing for primitive types.

Specified by:

isCompatible in interface TypeInfo

Overrides:

isCompatible in class JavaTypeProvider.JavaTypeInfo

Parameters:

other - - the other type to compare with this type.

Returns:

true if the test condition passes.

See Also:

TypeInfo.isCompatible(ariba.util.fieldtype.TypeInfo)

isWideningTypeOf

public boolean isWideningTypeOf(TypeInfo other)

Description copied from interface: TypeInfo

This method returns true if one type can be widening to another. This typically checks using referencing widening where this type is a superclass of other type. For primitive type, this method can also return true if the other type can be promoted to this type using java primitive widening. This method should also handle auto-boxing and auto-unboxing for primitive types.

Specified by:

isWideningTypeOf in interface TypeInfo

Overrides:

isWideningTypeOf in class JavaTypeProvider.JavaTypeInfo

Parameters:

other - - the other type to compare with this type.

Returns:

true if the test condition passes.

See Also:

TypeInfo.isWideningTypeOf(ariba.util.fieldtype.TypeInfo)

setElementTypeInfo

public void setElementTypeInfo(TypeInfo elementType)
