Method Detail

from_any

public void from_any(Any value)
              throws InvalidValue,
                     TypeMismatch

Overrides from_any() in DynAny

Specified by:

from_any in interface DynAnyOperations

Overrides:

from_any in class DynAny

Throws:

InvalidValue

TypeMismatch

to_any

public Any to_any()

Specified by:

to_any in interface DynAnyOperations

Overrides:

to_any in class DynAny

Returns:

an Any that holds a copy of this union

component_count

public int component_count()

Overrides component_count() in DynAny

Specified by:

component_count in interface DynAnyOperations

Overrides:

component_count in class DynAny

next

public boolean next()

Overrides next() in DynAny

Specified by:

next in interface DynAnyOperations

Overrides:

next in class DynAny

seek

public boolean seek(int index)

Overrides seek() in DynAny

Specified by:

seek in interface DynAnyOperations

Overrides:

seek in class DynAny

equal

public boolean equal(DynAny dyn_any)

Overrides equal() in DynAny

Specified by:

equal in interface DynAnyOperations

Overrides:

equal in class DynAny

get_discriminator

public DynAny get_discriminator()

Specified by:

get_discriminator in interface DynUnionOperations

Returns:

the current discriminator value

set_discriminator

public void set_discriminator(DynAny dynAny)
                       throws TypeMismatch

sets the discriminator to d

Specified by:

set_discriminator in interface DynUnionOperations

Throws:

TypeMismatch - if the TypeCode of the d parameter is not equivalent to the TypeCode of the union's discriminator

set_to_default_member

public void set_to_default_member()
                           throws TypeMismatch

sets the discriminator to a value that is consistent with the value of the default case of a union; it sets the current position to zero and causes component_count to return 2.

Specified by:

set_to_default_member in interface DynUnionOperations

Throws:

TypeMismatch - if the union does not have an explicit default case.

set_to_no_active_member

public void set_to_no_active_member()
                             throws TypeMismatch

sets the discriminator to a value that does not correspond to any of the union's case labels; it sets the current position to zero and causes component_count to return 1.

Specified by:

set_to_no_active_member in interface DynUnionOperations

Throws:

TypeMismatch - if the union has an explicit default case or uses the entire range of discriminator values for explicit case labels.

has_no_active_member

public boolean has_no_active_member()

Specified by:

has_no_active_member in interface DynUnionOperations

Returns:

true, if the union has no active member (that is, the union's value consists solely of its discriminator because the discriminator has a value that is not listed as an explicit case label). Calling this operation on a union that has a default case returns false. Calling this operation on a union that uses the entire range of discriminator values for explicit case labels returns false.

discriminator_kind

public TCKind discriminator_kind()

Specified by:

discriminator_kind in interface DynUnionOperations

Returns:

the TCKind value of the discriminator's TypeCode.

member

public DynAny member()
              throws InvalidValue

Specified by:

member in interface DynUnionOperations

Returns:

the currently active member.

Throws:

InvalidValue - if the union has no active member

member_kind

public TCKind member_kind()
                   throws InvalidValue

Specified by:

member_kind in interface DynUnionOperations

Returns:

the TypeCode kind of the currently active member.

Throws:

InvalidValue - if the union has no active member

member_name

public String member_name()
                   throws InvalidValue

Specified by:

member_name in interface DynUnionOperations

Returns:

the name of the currently active member.

Throws:

InvalidValue - if the union has no active member

destroy

public void destroy()

Specified by:

destroy in interface DynAnyOperations

Overrides:

destroy in class DynAny

current_component

public DynAny current_component()

Specified by:

current_component in interface DynAnyOperations

Overrides:

current_component in class DynAny
