int com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getColumnIndex

(

String

columnName

)

Returns the internal index for a column This method is only provided for performance reasons. When looking up the value, as well as read and write permissions on a column, first use this function to determine the index value. After that, use calls which ask for the index instead of the column name.

Parameters:

columnName

Returns:

the internal index for a column

IDataTable com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getDataTable

(

)

Collection<MetaObjectAccess> com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getMetaObjectAccessList

(

)

Returns the total collection of MetaObjectAccess objects for this row.

Returns:

the total collection of MetaObjectAccess objects for this row.

abstract <T> T com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getPrimaryKeyValue

(

)

[pure virtual]

Returns:

returns the generated GUID for this row based on the database id of this row, the name of the object type this row represents and the datastorecode

abstract IDataTableSchema com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getSchema

(

)

[pure virtual]

Returns the schema of the table of this row.

Returns:

the schema of the table of this row

abstract String com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getSpecificTableName

(

)

[pure virtual]

Only for internal use.

Returns:

abstract <T> T com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getValue	(	IContext	context,
		String	columnName
	)		[pure virtual]

Returns the value of the column with the specified name in this row.

Parameters:

context	the context.
columnName	name of the column from which the value must be returned.

Returns:

the value of the specified column in this row.

Exceptions:

IllegalArgumentException

when the columnName does not exist in this Row.

abstract <T> T com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getValue	(	IContext	context,
		int	columnIndex
	)		[pure virtual]

Returns the value of the column with the specified index in this row.

Parameters:

context	the context.
columnIndex	index of the column from which the value must be returned.

Returns:

the value of the specified column in this row.

Exceptions:

IndexOutOfBoundsException

when the index exceeds the count of columns of this row.

abstract <T> T com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.getValue	(	IContext	context,
		IDataColumnSchema	dataColumnSchema
	)		[pure virtual]

Returns the value of the column with the index of the specified schema in this row. This method is identical in function to getValue(dataColumnSchema.getIndex()).

The returned value can be a primitive object or another DataTable object. When in the original request simply attributes of metaobjects were requested, the returned values will be of the primitive Java type corresponding to the type of the attribute. When aggregate functions are combined with simple attributes, this will also be the case. However, when more complex OQL expressions are used, it isn't always predictable which type the returned values will have. It depends on the expression type and the database type.

Parameters:

context	the context
dataColumnSchema	schema of the column from which the value must be returned

Returns:

the value of the specified column in this row

abstract boolean com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.hasColumn

(

String

columnName

)

[pure virtual]

Returns whether the column name is defined in the schema or not.

Parameters:

columnName

Returns:

true if and only if the column name is defined in the schema

abstract boolean com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.hasReadAccess

(

int

columnIndex

)

[pure virtual]

Returns whether the user which has retrieved the data, has read access to the given column.

Parameters:

columnIndex

the column to retrieve the access information.

Returns:

whether the user which has retrieved the data, has read access to the given column

abstract boolean com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.hasWriteAccess

(

int

columnIndex

)

[pure virtual]

Returns whether the user which has retrieved the data, has write access to the given column.

Parameters:

columnIndex

the column to retrieve the access information.

Returns:

whether the user which has retrieved the data, has write access to the given column

abstract void com.mendix.systemwideinterfaces.connectionbus.data.IDataRow.setSpecificTableName

(

String

subjectName

)

[pure virtual]

Only for internal use.

Parameters:

subjectName
