Constructor Details

ProDataObjectMetaData

public ProDataObjectMetaData(String tableName,
 int numFields,
 boolean bimageFlag,
 int numIndexes,
 String multiIxCols,
 String xmlNamespace,
 String xmlPrefix)

Creates ProDataObjectMetaData (table definition) with specified data.

Parameters:

numFields - Number of fields

bimageFlag - True if BEFORE-TABLE defined in 4GL (for table), else False

tableName - Table name in 4GL

xmlNamespace - Namespace for XML Serialization

xmlPrefix - Prefix for XML Serialization

Method Details

setFieldMetaData

public void setFieldMetaData(int fieldNum,
 String name,
 int extent,
 int proType,
 int userOrder,
 int xmlMapping)
                      throws ProDataException

Sets the MetaData for a field of the input ProDataObject.

Parameters:

fieldNum - 1-based field number of the field to set schema for

name - Field's name

extent - Field's extent. If field is not an array field, this should be 0.

proType - Field's data type - one of the PRO_XXX constants supplied by com.progress.open4gl.Parameter.

Throws:

ProDataException

getTableName

public String getTableName()

Returns:

Table name

getBImageFlag

public boolean getBImageFlag()

Returns:

BeforeImage value (4GL Table BEFORE-TABLE attribute). If true, table is updateable.

getFieldCount

public int getFieldCount()

Overrides:

getFieldCount in class DataObjectMetaData

Returns:

Number of fields

getNoSchemaMarshal

public boolean getNoSchemaMarshal()

Returns:

True if the table data will not be marshaled with schema info to the AppServer, else it returns False.

setNoSchemaMarshal

public void setNoSchemaMarshal(boolean noSchemaMarshal)

If flag is set to true, when table's data is marshaled to AppServer, it is sent without schema info (suppresses index descriptions and all field info)

Parameters:

noSchemaMarshal - flag

getUserOrder

public int getUserOrder(int field)

Overrides:

getUserOrder in class DataObjectMetaData

Parameters:

field - 0-based field index

Returns:

User order position of specified field

Returns:

Field's data type (found in com.progress.open4gl.Parameter) for specified field

Throws:

ProDataException

getExtent

public int getExtent(int field)
              throws ProDataException

Parameters:
