Constructor

The ProDataObjectMetaData class has one constructor:

Syntax

ProDataObjectMetaData(String tableName, int numFields, boolean bimageFlag,                       int numIndexes, string multiIxCols,                       String XMLNamespace, String XMLPrefix)

tableName

Specifies a name for the specified ProDataObject type (and collection). This name is typically identical to any 4GL temp-table to which this collection is mapped.

numFields

Specifies the number of fields (column properties) in the specified ProDataObject type.

bimageFlag

Specifies true if the corresponding Progress 4GL temp-table is defined with the BEFORE-TABLE option, indicating that the temp-table (and hence the ProDataObject collection) can be modified. Otherwise, this value must be false and you cannot modify the data contained in the collection.

numIndexes

Specifies the number of indexes on the table.

multiIxCols

Specifies null if there are no indexes or a formatted string that contains all the index info for this temp-table, as follows:

Syntax

"[primeUniqueFlag,primeFld1[,primeFldn]...:primeIdxName.] [uniqueIdxfld1[,uniqueIdxfldn]...:uniqueIdxName.]..."

primeUniqueFlag

Specifies a primary index with a value of 1 if the index is unique and a value of 0 if the index is not unique.

primeFld1[,primeFldn]...

Specifies the names of one or more fields involved in the primary index.

primeIdxName

Specifies the primary index name.

uniqueIdxfld1[,uniqueIdxfldn]...

Specifies names of one or more fields involved in a unique secondary index.

uniqueIdxName

Specifies a unique secondary index name.

Thus, a table can have no indexes, a single primary index followed by zero or more secondary unique indexes, or it can have a single secondary unique index followed by zero or more additional secondary unique indexes. Some examples follow:

Table with a single primary index:

"1,custNum:CustIndex"

This is a primary unique index named CustIndex with one column named custNum.

Table with a single secondary index:

"orderDate:OrderIndex"

This is a secondary unique index named OrderIndex with one column named orderDate.

Table with two indexes:

"1,custNum:CustIndex.orderDate,shipDate:OrderIndex"

These two indexes include:

A primary unique index named CustIndex with one column named custNum.
A secondary unique index named OrderIndex with two columns named orderDate and shipDate.
Table with three indexes:

"0,custNum,custName:CustIndex.orderDate:OrderIndex. itemNum:ItemIndex"

These three indexes include:

A primary non-unique index named CustIndex with two columns named custNum and custName.
A secondary unique index named OrderIndex with one column named orderDate.
A secondary unique index named ItemIndex with one column named itemNum.

XMLNamespace

Specifies the namespace for XML serialization or null.

XMLPrefix

Specifies the prefix for XML serialization or null.
