public interface JCoRecord
extends Serializable, Cloneable, Iterable<JCoField>

Base interface for all data containers used throughout the JCo framework. Implementations take care of internal bookkeeping of buffers, metadata, etc. In addition it provides a rich set of get/set methods which allow a convenient access to the individual fields that make up a record. Getter and setter methods support conversion of field values, which are summarized by the following table:

Method Detail

getMetaData
```
JCoMetaData getMetaData()
```
Returns the appropriated metadata object that was used for creation of this record.

Returns:

JCoMetaData instance of the appropriated metadata object

clear
```
void clear()
```
Clears the record and resets everything to its initial state.

clone
```
Object clone()
```
Clones the record instance.

Returns:

a cloned instance of JCorecord

copyFrom
```
int copyFrom(JCoRecord source)
```
Copies the matching fields from the source record into this record. Data fields are considered to be equivalent if the name and type of two fields match. The data will be copied and converted as best as can, i.e. strings will be cut off if the source field is longer than the destination field, or they will be filled with spaces if the source is shorter than the destination, etc. If a single conversion fails, the whole copy operation will fail and the record will be left untouched. If the JCoRecord is a JCoTable, then the data from the source will be appended. This means that, if the source is a JCoStructure a single row will be appended to the end of the JCoTable, and if the source is a JCoTable all its rows will be appended to the end of the JCoTable.
If the JCoRecord is a JCoStructure or a JCoParameterList the data will be overwritten by the source. In case that the source is a JCoTable, the data is copied from the current row, i.e. the row the row pointer points to.

Parameters:

source - the source record from which to copy the data

the number of matching fields (columns)

Parameters:: index - of the field that should be written to out; writer - writer instance used to write
Returns:: the instance passed as parameter writer
Throws:: ConversionException - if the field is complex; JCoRuntimeException - with the key JCoException.JCO_ERROR_FIELD_NOT_FOUND if the field with the name is not available; IOException - if writer throws IOException

write

Writer write(String fieldName,
             Writer writer)
      throws IOException

Writes the named field to the provided Writer.
The method writes out the internal char array representation avoiding temporary objects. The output depends on the field type:

Field data type	Output to the Writer instance
`JCoMetaData.TYPE_CHAR`	char buffer without trailing spaces
`JCoMetaData.TYPE_DATE`	chars in format yyyyMMdd
`JCoMetaData.TYPE_TIME`	chars in format HHmmss
`JCoMetaData.TYPE_UTCLONG`	chars in format yyyy-MM-ddTHH:mm:ss.SSSSSS
`JCoMetaData.TYPE_NUM`	char buffer
`JCoMetaData.TYPE_STRING`	string chars buffer
`JCoMetaData.TYPE_XSTRING`	hexadecimal representation of the xstring byte buffer
`JCoMetaData.TYPE_BYTE`	hexadecimal representation of the byte buffer
`JCoMetaData.TYPE_BCD`	char based representation of the number
`JCoMetaData.TYPE_FLOAT`	char based representation of the number
`JCoMetaData.TYPE_INT1`	char based representation of the number
`JCoMetaData.TYPE_INT2`	char based representation of the number
`JCoMetaData.TYPE_INT`	char based representation of the number
`JCoMetaData.TYPE_INT8`	char based representation of the number
`JCoMetaData.TYPE_DECF16`	char based representation of the number
`JCoMetaData.TYPE_DECF34`	char based representation of the number
`JCoMetaData.TYPE_STRUCTURE`	not possible, exception will be thrown
`JCoMetaData.TYPE_TABLE`	not possible, exception will be thrown
`JCoMetaData.TYPE_ABAPOBJECT`	not possible, exception will be thrown

Parameters:: fieldName - name of the field; writer - write that is used to write operation
Returns:: the instance passed as parameter writer
Throws:: ConversionException - if the field is complex; JCoRuntimeException - with the key JCoException.JCO_ERROR_FIELD_NOT_FOUND if the field with the name is not available; IOException - if writer throws IOException
Since:: JCo 3.0.7
