Method Detail

getSetField

public F getSetField()

getFieldValue

public java.lang.Object getFieldValue()

getFieldValue

public java.lang.Object getFieldValue(F fieldId)

Description copied from interface: TBase

Get a field's value by field variable. Primitive types will be wrapped in the appropriate "boxed" types.

Specified by:

getFieldValue in interface TBase<T extends TUnion<T,F>,F extends TFieldIdEnum>

Parameters:

fieldId - the field whose value is requested.

Returns:

the value of the requested field.

getFieldValue

public java.lang.Object getFieldValue(int fieldId)

isSet

public boolean isSet()

isSet

public boolean isSet(F fieldId)

Description copied from interface: TBase

Check if a field is currently set or unset.

Specified by:

isSet in interface TBase<T extends TUnion<T,F>,F extends TFieldIdEnum>

Parameters:

fieldId - the field to check.

Returns:

true if the field is set, false otherwise.

isSet

public boolean isSet(int fieldId)

read

public void read(TProtocol iprot)
          throws TException

Description copied from interface: TSerializable

Reads the TObject from the given input protocol.

Specified by:

read in interface TSerializable

Parameters:

iprot - Input protocol

Throws:

TException - if there is an error reading from iprot

setFieldValue

public void setFieldValue(F fieldId,
                          java.lang.Object value)

Description copied from interface: TBase

Set a field's value by field variable. Primitive types must be "boxed" in the appropriate object wrapper type.

Specified by:

setFieldValue in interface TBase<T extends TUnion<T,F>,F extends TFieldIdEnum>

Parameters:

fieldId - the field whose value is to be set.

value - the value to be assigned to field.

setFieldValue

public void setFieldValue(int fieldId,
                          java.lang.Object value)

write

public void write(TProtocol oprot)
           throws TException

Description copied from interface: TSerializable

Writes the objects out to the protocol

Specified by:

write in interface TSerializable

Parameters:

oprot - Output protocol

Throws:

TException - if there is an error writing to oprot

checkType

protected abstract void checkType(F setField,
                                  java.lang.Object value)
                           throws java.lang.ClassCastException

Implementation should be generated so that we can efficiently type check various values.

Parameters:

setField - the field to assign value to.

value - the value to be assigned to setField.

Throws:

java.lang.ClassCastException - if the type of value is incompatible with the type of setField.

standardSchemeReadValue

protected abstract java.lang.Object standardSchemeReadValue(TProtocol iprot,
                                                            TField field)
                                                     throws TException

Implementation should be generated to read the right stuff from the wire based on the field header.

Parameters:

iprot - input protocol from which to read a value.

field - the field whose value is to be read from iprot.

Returns:

read Object based on the field header, as specified by the argument.

Throws:

TException - on error during read.
