Null constructor creates an empty SegmentHeader.

See Also:

SegmentHeader

EvioSegment

public EvioSegment(SegmentHeader segmentHeader)

Parameters:

segmentHeader - the header to use.

SegmentHeader

EvioSegment

public EvioSegment(int tag,
                   DataType dataType)

This is the general constructor to use for a Segment.

Parameters:

tag - the tag for the segment header.

dataType - the (enum) data type for the content of the segment.

Method Detail

getStructureType

public StructureType getStructureType()

This implements the abstract method from BaseStructure. It is a convenience method use instead of "instanceof" to see what type of structure we have. Note: this returns the type of this structure, not the type of data this structure holds.

Specified by:

getStructureType in interface IEvioStructure

Specified by:

getStructureType in class BaseStructure

Returns:

the StructureType of this structure, which is a StructureType.SEGMENT.

See Also:

StructureType

toXML

public void toXML(javax.xml.stream.XMLStreamWriter xmlWriter)

Write this segment structure out as an XML record. Integers written in decimal.

Specified by:

toXML in class BaseStructure

Parameters:

xmlWriter - the writer used to write the events.

toXML

public void toXML(javax.xml.stream.XMLStreamWriter xmlWriter,
                  boolean hex)

Write this segment structure out as an XML record.

Specified by:

toXML in class BaseStructure

Parameters:

xmlWriter - the writer used to write the events.

hex - if true, ints get displayed in hexadecimal

getXMLElementName

public java.lang.String getXMLElementName()

Get the element name for the bank for writing to XML.

Specified by:

getXMLElementName in class BaseStructure

Returns:

the element name for the structure for writing to XML.
